Definitely gorgeous. But beauty is only skin deep. the commitment to getting that cover off is appreciated.
I have the hands of a surgeon with my rubber mallet skillz
@@wal hey big d can you do a review on the audiopipe aq3000 is a dj amplifer and I personally own one and I want to know what the true rms power output is like
"Rated like a BOSS, Literally" had me rolling......... LOL.......................
Facts are facts, yo!
Shit they were closer than a boss would have been
Big D!!!! Thanks so much for what you do! We appreciate you!
If you can’t be great just be beautiful. Should be this amps motto.
Williston audio is THE BEST AND EXPLAINING AMPS SUBS ETC.
In combination with barevids!
U should watch barevids . He is way more in-depth.
@@speakerpat xd both mentioned the same thing 😂😂.
Need to watch EMF audio
@@KuntalGhosh what? So, you're recommending another channel for whatever reason, but you're on this channel... Make your own videos so we can disrespect your work...
Thats what you call a "All show and No Go!" amp!
And if it stops, who ya gonna call?
That was the first line in my reply! I didn't read the rest of the comments, before I commented. ("All show, no go")
@Yosë This would be the amp I would use, if I was building a car show car. It looks beautiful, and yes, it does work well enough for Harrah's Autorama.

Thanks bro I been looking at one this and I might buy one thank for the info
Pin your comment to the top for Stereo Integrity & The other companies... They deserve that b/c most will not watch the whole vid & think all amps are same & go w Alibaba due to price.
Glad u made this comment!
Lawd I thought you were gonna shatter that plexi with the pliers! 🤣😂 Beautiful amp and great video as always
Lawd those tolerances was tight!
I've shattered tempered glass with pliers like that by accident before when I was younger and dumber. My car window fell off track once, and I couldn't grab it with anything else but the needle nose vice grips I had handy. Got the window 3/4 of the way up, and pow! It sounded like an m80 went off and the window exploded everywhere. I was cleaning up chunks of glass for an hour or two after that one lol.
@@catch22frubert this is thick lexan, not regular glass. I bet that was scary, kinda like blowing up an amp :-P
Lpo
Definitely one of the best looking apps I’ve seen since the early 90s. Too bad it didn’t sound better I’d stick it right next to my linear power 2.2!
You have one of my favorite channels. Great work as always.
God it’s so beautiful. I hope someone makes one of these that actually makes power that it’s rated at.
The actual stereo integrity amps should.
Stereo Integrity
I plan on running all vivaldi soon... beautiful amplifiers
I have a Teampie TP-8504 , it only cost me $89 plus shipping so for the price it was a great deal , (they thought I wanted to test it as a sample , before ordering a containers worth lol). But I also received an email last month from the real buildhouse that stereo integrity uses so I'm going with them next. Teampie does have great mono amps that are used by deaf bonce and emf.
👌😬👍
Who is the buildhouse that SI uses? I want to eliminate their bullshit markup
As always...thank you for the video.
Thanks for watching and commenting!
Stereo Integrity needs to send you their amp so you can dyno it and assure the public there is a difference between the brand and the knock off.
Lol.."A little bit of persuasion🔨"..That tends to work most of the time on a variety of things/people..Great video as always Big D 👍
👌😬👍
Nice video big D I was curious about this amp. Now that stereo integrity for sure is going to be a good one. And the Vivaldi’s are legit aswell
Yeah boi
That amp is destined to become a flea market one sold for more than a real SQ amp. Thanks for the test! And if you're looking for a SQ amp stick to the real deals!
I'll be waiting for the stereo integrity bench test senor.
As always thanks Big D. Great dyno. Amazing looking amp and if it sounds good then it’s still a good buy.
Thanks for watching and commenting!
No matter what they put internal parts high grade etc...b.s.. Nothing can beat the SQ of late 80s early 90s. Class A made in usa amps....
Owned many old school amps... and some new high end like BRAXx Graphic edition..etc... McIntosh... Etc.. All great sound... But sold them all and now just running my fav Adcom amps.... Adcom amps. Built by Mr .Nelson... One of the best unique sound..... You can listen to all day ..and never get tired of the adcom sound..
This amp is the equivalent of average insta “models” expensive but nothing to offer.
Look real nice but don’t put out lol
Interesting video. Very detailed for a “knock-off” but for some reason I would not be motivated to buy one, and after watching your break down of it, I would absolutely ignore it even if it was on sale. 👍🏼
This is why I buy stuff like this so you guys don’t have to wonder...
@@wal And we appreciate it!!
I love the look of that amp! Great video Big D Wiz!! 👍👍
She’s a looker fo sho
Absolutely stunning. Work of art man. This makes me feel like I'm looking at an older art series.
And it specs like the cheap garbage it is lol
Nick from Stereo Integrity is a long time friend of mine. I usually get the prototypes of his speakers for testing and am amazed his new amp has already been copied.
Dude!
You know me on SSQ. I just friend requested you yesterday. The prototype SQL12 he makes is in my car right now. Amazing sub!
Amazing analysis! Thanks for making these videos.
I bought an amp off AliExpress that only made half its rated power. I opened a dispute on AliExpress and got half of my money back.
🤣 bro half the money back I’m dead
I want to see you test the similar looking amplifiers from vivaldi and stereo integrity. This would include close up shots of the component differences which are easy to overlook for a regular person.
I’ll try to do this
Thx to Big D!! The review of the Savard HI-Q 8” subs. I bought them for my truck Running 4 in my single cab dodge running a 3 k amp. And all I can say is OMG. Very happy.
That amp is beautiful! The one that is not a knock off.
Love some good audio phoolery!
Best comment yet!
After seeing the video I purchased one of these on eBay for $100. Hooked it up and tested it on my bench. I thought it sounded great.
Thing has less than 50DB of channel separation and the THD is ridiculously high.
So you didn’t try to remove those two middle covers to see if there’s anything in there??? And brother you need to make your own line of amps to sell I bet everyone would buy your equipment cause they know your a honest amp tester and whatever you sell will be top notch
that's the most beautiful scam i've ever seen!
It's really not I mean that amp is comparable to so many amps for the last 20 years and still cheaper than a lot of those amps were.
There was a really sexy chinese fuel saver full of huge, dry caps. Only 1 cap was connected and real.....but I still almost bought one. It looks great.
@@MacNifty its actually a TEAMPIE AMPLIFIER YOU CAN BUY ON ALIBABA FOR FAR LESS THAN WHAT ST IS SELLING THEM FOR. CHECK ON THERE FOR YOURSELF. MY CAPS LOCK IS STUCK LOL SORRY NOT YELLING.
@@hicknopunk only 1? Baahaha
TO-3 transistors, that's rather unusual nowadays, and the MJ15024 (of which there is one per channel) is one of the suggested replacements for the output transistors in the 1970s/80s version of the Peavey CS-800...
It doesn't sound bad. As long as you run it with matching components, it'd be nice in a display demo set up. Just have to be modest about it's output.
It is eye candy! but those numbers don't impress me enough to hunt one down. Thanks big d, for the review and test👍
Thanks for watching and commenting!
All show, no go! You have to admit, it is beautiful to look at. I do like the TO-3 diamond base power transistors. Most modern amplifiers run TO-247 "flat packs". Nothing wrong with the flat packs, (TO-220, T0-247, TO-264) I use these case styles in my designs all the time. It's just unique, to see these "old school" case styles in modern amplifiers.
It would be interesting, to test the frequency response of this amplifier, compared to less expensive amplifiers of similar power rating. The power supply is definitely a try and a miss. I would expect much better, from a "high end" amplifier. (good choice of MOSFET's in the power supply)
I dig it for the aesthetics
I would be scared to make a transaction on Alibaba. Thanks for the testing Big D!
I won’t do any requiring bank transfer. PayPal only via Goods
I love my audio system twister amplifiers....they are all rates at 2ohms bridged. Small footprint and some decent.
Return of the FLIR!!!
Hey Derrek great vid as always! I'm watching you from Maine and I myself have carried many brands of equipment throughout the years, including some very high end German and English..etc..etc.etc! This amp looks similar to Helix Precision class in design but no-way I'm sure in quality & design as I used to deal in Helix I know better! lol! But anyways it sounded descent for the price tag and your bookshelf speakers really bring out the highs[ are they silk tweets?] So aside from this my question to you is, who makes that black power supply to the left[only could see the corner of the face] I believe it resembles a Massive Audio BP series 200Amp power supply, could you please give some feedback on it either way if I'm right on brand or wrong would be a great help! I no longer run my business but still build systems for my family and friends...My personal BMW 3 series is in build process with 5 Massive Audio Blade series[older models] amplifiers, with the Cap-B extensions a single 12" Helix Esprit carbon flat sub glassed in to the trunk[non-removable] all Orion XTR components[5 pairs mixed 6.5" & 5.25"] play the beats with 2 8" MB Quart shallows in the footwells[glassed in removable floor pods] for mid-bass 80-120hz dialed in via the 2 main 4 channels with built in band-pass x-overs! this being said, I need to power all this stuff with a supply[car is up for winter, show only] other than the 2 Optima Batteries while I finish my build, the power supply I have is a TrippLite 35Amp[old school] its extremely powerful but not above 35 Amps continuous and I don't want to cook it, because it's no longer made! So I'm wracking your brain, what do you use? What do you suggest? keep in mind I don't have Steve Meade dollars or requirements for a large 240Volt like his, but I have a feeling you've been doing this stuff long enough to know about what I'm looking for, so any info you can give me would be awesome, I am Old School as well[49 years old] car audio veteran and see the electronics world has dramatically changed, from my upbringing of this field! I started out with Carver, Concord, JBL, ADS Technologies[Orion/PPI/ ADS], ADCOM Car Amps, Rockford Fosgate[older Punch 30/45/75/150 & of course DSM IX], Eclipse, Phoenix Gold, Kicker, Alpine..etc..Then I opened up my own shop selling Helix/Brax, Genesis, U.S. Amps, RE Audio, MASSIVE, Audio Control, Planet Audio[I made it work], Powerbass Extreme, etc... so enough with my resume' you get the picture I've worked with many brands in my lifetime! Feel free to pick my brain too! thanks for reading this, maybe you could do a power supply video as I'm sure others would appreciate too!
Sincerely,
Scottyz Car Audio & Automotive Specialties
Call some of your closest car audio shops and ask if they know who has a good used one for sale. Out here in Phoenix, there's always audio shops closing down and selling their equipment to the highest bidder...
Could you please review a German made amp, the HELIX H400 esprit??
Love seeing video posted 2 minutes ago
Thanks for watching and commenting!
Those crooked boards got me grinding my teeth
Thank you for another great video Big D!
Thanks for watching and commenting!
i really want to know whats under those covers. its odd the way the overall heat shot looked imo.
There are transformers under 😉
@@maxvangeffen2098 I'd love to be able to pull them off to know though 😉
Hey it looks good, what’s more important than aesthetics in car audio ?
Uhhhh....sound quality??
Well, the pretty box is useful.
👌😬👍
Maybe the Vivaldi amp is more expensive but how do you know it doesn’t contain counterfeit parts? Great review thanks for taking one for the team!
For a class a/b amp 87watts a channel at 4ohms is really good. I dont want crossovers or anything else in my amp so I'd use one
Just go with American made zapco if you want true SQ! :-) if you're wanting to run old school equipment zap go still a good choice but audio art in Boston acoustics may be an excellent choice as well.
Love some Zapco!
Thx Big D, good job! Beautiful Amp I wonder what Barevids would have to say if he tore into one.
Finally an amp that's not a cookie cutter design!
Would have been nice to put the switching frequency of the DC converters a bit higher so it doesn't make all kinds of weird high frequency noises.
Yeah, they could get a bit more power out of single pair of 15024/25 Motorola output transistors, easily 100W, but it has rather 'small' power supply, some +/-30V on rails. It should be able to take 1ohm no problem. These are older, 5MHz, 15A, 250W trans from the '80s, that make stable, simple, clean sounding amps. Needs more voltage on rails (and silicon) to meed the factory specs.
If this is a 4ch SQ amplifier testing it at subwoofer frequency should cause it to underperform shouldn't it?
The amp looks awesome and to me it sounds pretty good thru the video. I like it but I only seen the one Chinese company selling it.
Big D Wiz if you ever run out of car amplifiers to test get into other parts of audio like home hint hint :-) ps my new beats tour3 sound real good with this vid
Lol the elacs are nice tho! I like to play it safe for sql. Jl amps, focal doors, good to go donezo. 👍 great video as always
The coil whine is a complimentary feature to test your high frequency hearing.
Right!
I thought you were going to remove the covers and see if there was anything under them.
Still a gorgeous looking amp no matter what.
I don't get your tests. Where does the manufacturer claim it is rated at 150W at 1% THD? What they say is 0.1% THD at 80% power. But you didn't test this.
Oh snap! You produced this?
Nice Big D. 9:28
That explains why it's a familiar beat and I just now realized I've only heard it on your channel LOL.
Yeah back before YT had tracks we could use
@@wal ahh, I see. I see a hidden Talent you can use if they do ever make one universal rating system for amplifier ratings. Impressive!
I have always liked focal and audison. I wander if the SI amps are as good
Awesome video Big D shows you get what you pay for. I want to ask is wolfram on the list for testing? Reason for asking I’m thinking of purchasing a AW9000.1 which I believe is the W7500.1 rebadged.
Great video keep knocking em down brotha. I dig how you find amps like these. I'm tempted but id be worried n prob would save for the real deal stereo integrity. Did it sound crisp and clear? More so than another sq amp youve listened to recently?
It did not sound notably better than any recent amp I’ve listened to
@@wal well although it's a extremely good looking amp, I mean like "damn girl!!" im not impressed with the numbers. Big thing is how awesome it is of you to pay the money for it, thoroughly test it, so everyone else knows the scoop about it. So for that bro, thanks big D
@@kswis I was genuinely curious about this one and had to try it out for myself and based on the response on the pics I posted, it sure seemed like other people would like to know as well...
@Pamfman it's da truf
If you get a chance see if you can get your hands on one of these and test it.

Can you do a review of the new wolfram o-2400 thank you keep up the good work
That would be O, O, O so cool 😎
Toujours top tes Vidéos 👍
I'm very late to the party, but would love to see whats under the Chrome covers in the center
The power supply transformers. Good idea if the covers are metal, but they are probably plated plastic.
Those transistors are actually good stuff if you match them. It's odd the amp made such little power, those components are capable of much more.
@@2slofouru I am curious, the heat sensor didn't show as high of a temp on the center two. My guess is just for looks, but I could be wrong.
nice break down
It's sad we can't trust any of these chinesium amps and the good chance the "high end" parts aren't actually counterfeit.
Especially the inexpensive ones
Sometimes some of these factories have a defective production run and like Ollies and Big Lots and other companies who have buyers that buy defective items or that did not pass the stringent quality test they will scoop them up by The Lox it's quite possible that these might be true high quality but they got them with a quality issue and they were going to be destroyed but someone took them from the factory and knew that they could make a shitload of amplifiers with them.
The most deceiving look is the profile picture for this video where I thought that was brass or gold and it was neither it was just Chrome.
Great work man!! Can you do any of the HD Jl Audio amps?
I tested the HD1200/1 and planning the 900/5 soon
Sweet, can't wait to see. Thanks for all the hard work!
Looks like Sound Integrity amps. Wonder if are using this.
man this channel makes me buy stuff for the car i never ride lol keep it up man!
also me thinks the crome cover migth be touching one of the toroids and so the noise... maybe they forgot to insulate the inner part of the cover
Maybe the switching frequency is too low?
Hmm.. Sanken transistors are still considered best for audio then? Interesting, i still have Rotel amps made in the late 70s/early 80s that used custom Sanken power ICs, some of the first integrated chip amps.. Not many watts but they do sound rather impressive! My current Rotel though (RA-970BX) driving two pairs of Kef Coda III (8ohm each) seeing a 4ohm load does quite well! (Toroidal transformer, 8 power output transistors rated 60W RMS x2 @ 8ohm, 90W RMS @ 4ohm!) Specs are fairly impressive should you ever look it up, including the schematics, plus these Kef speakers..wide bandwidth near field studio monitors, they sound incredible! Go down below 30Hz, no sub really needed with 4 of them! Haha..pisses the neighbours off nicely!
Thanks for watching and commenting!
Looks great, I’ll take the Zpaco.
Somehow I find listening to his Elac speakers off axis then the rest of the video.... Although I do lust after some of his equipment...
Nice looking. What would you say is the best budget sq amp?
Sony XM-GS4 is an incredible value. The sound is real nice. I'd send it to Big D for testing, if he wants.
Good video, greetings from Colombia and I congratulate you on your channel, it is possible that you will test the ORION XTR 750.4 amplifier, thank you for your attention, thank you very much.
Thanks for watching and commenting!
If it's aTeampie, it's got to be good!
👌😝👍
Id give two thumbs up just for using diff music esp the trap song. It shows much better real word bass of what most of us prob listen to now a days lol.
i like the design but not sure the covers hiding the transformers is to my taste personally.
also side bar - glad the zoomed dyno screen has moved on, honestly it was kinda distracting as id always watch the one on the unit.
just my 2c, cheers
The two outer “cans” are transformers, the inner two cans are the filter coils tied to the rail caps. Just a guess.
Maybe, or the center covers are just hiding the truth 🤣
Thumbs up before even watching the video just b cuz
You da man!
That relay kick on tho
It would be fantastic, to get info about slew rate & damping factor of those amps for rating the ability to control LS, or subs ... 🙋🏽♂️Ⓜ️
Would you please pass the Gray Poupon?
Bad power but beautiful amp. Flexing the Elac bookshelfs.
@@In_Need_of_a_Savior Maybe but wouldn't know it over youtube. I just like the look of it Is all and class a/b usually have a better sound than the others.
What i see is the cheap generic 3w green resistor instead of 5w ceramic wirewound resistor near the final capacitor. Wirewound is best resistor for audio, metal film would be next. The green resistor there could be metal oxide(thick film) or carbon film one, its a no.
The smaller multiple caps is a way to reduce the price instead one or two set high quality audio. Not an indication of the quality of the amp.
For sq i would want a 3 stage gain transistor construction(ab class amp), emi power filter, metal film resistor, mkp/mkm(red or orange rould be nice) capacitor, audio grade elco and audio grade opamp.
There should not be a generic parts outside the inverter section. I prefer smaller but numerous elco. Bigger caps just dont do well in the higher freq than their smaller variants.
They do seem to be well matched at least
Hmmm that Vivaldi amp looks a lot like a Ground Zero designed amp..The GZUA 4.150SQ
This is not the ZED SQ amp I'm looking for...
Maybe the older stuff, his quality control went down hill, high rate of defects and the worst customer service...
It would have been nice to compare this to the original, yeah?
So this is the Alibaba version not the Stereo Integrity version ? The SI version has upgraded capacitors ( nichicon etc ) & other parts that are in the signal path that this amp doesn’t. Very similar but two different layouts as well. Interesting to see this amp sounds vs the SI one. The ratings can be proven but SQ is always subjective.
I would love to see what a PPI ICE1000.4 does ..... no one on you tube has a Dyno of one I would love to see what I bought.
12:45 if you see it, at the capacitors, the printing is busted, so its fake caps, also the output transistors may be also fakes :D
Does the amp dyno allow for lower distortion ratings for these SQ amp tests? I remember old school amps being rated at something like .04%?
It would do even less power.
PPI and Orion was rating theirs at .02 thd
Did you do the thermal image with the acrylic on? Allthough it is see through it will shield most of the heat / infrared. I guess that amp got quite a bit hotter than you measured
