Beautiful amp. I do love the SQ stuff. It does cost a lot, but compare it to a similarly powered home amplifier, and the price is not too bad for an amp capable of 4x150w in 8 ohms (certified), or 500w x2 in 8 ohms bridged.

This speaker shop where I live has a bunch of old school amps and speakers. Fulton, sentrek, Pyle when they were made in USA, Blaupunkt, MTX, Audiobahn. They are a legit shop if you want me to give you info to Google them
The TO-3 Cased transistors are certainly an oddity for an audio amplifier but there are quite a few N channel Mosfets that utilize that design but I kinda dig it because it's old school.
They were used in pro audio applications for many years, Peavey and QSC used them into the 90’s before phasing them out in their switch overs to Class H and then to class D. T-03 was super common in instrument amplifiers for the power stage. Very durable and it’s sad they were phased out.
As I mentioned before class A is 0.000001% THD and class B 0.003% THD from what I can remember in the 1980's, I have not seen 1 car amplifier that is lower than 0.01%THD. Where they get there classification from is anyone's guess. It is a class D amp at 0.03% THD. I have a LANZAR Heritage HTG668GBT that has lower THD, 0.01%. THD is the first choice for pure quality, then comes frequency response. The greater the lower and upper frequencies the more representation between.
Watching as my kids were falling asleep n suddenly dad exclaims with "holy shit that's massive!" Oops. That is a gorgeous amp n I've never seen 10k mf caps before. That's bannanas! Along with the efficiency that's an awesome amp fo sho! Thanks for buying to share with us folks.

@BigD: We know that you're into that killah bass. We all love that. Using bookshelf speakers along with a gigantic sub, shows that you're interested in home speakers too. So, try this out for us, if you would: make some (3 or 5 pair) of speakers with various sizes of exciters mounted to matching scale-sized foamboard. Then, team those with a powered home sub. Test the frequency responses to see what combination from the various pairs is best. With exciters, do they benefit from bigger panels? Seems like higher power exciters would be able to "drive" bigger panels or reproduce lower tones, but I could be wrong. These components are super cheap, but we (your viewers) don't have any testing equipment to try to measure the frequency responses. If what you're powering doesn't make a flat response curve, it won't sound right. If that curves varies much (up and down the measurement scale), it won't sound right. Now I realize this is a bit off your typical testing regimen, but even if you measure subjectively at the clarity added by introducing a 2nd, 3rd, etc. pair of exciters to the show, it would be pretty cool. Since you like to mess with boxes, and the like, this might be interesting to you. Dayton Audio (and a few other companies) make a couple styles of exciter that utilize various power amounts as their intended input peak. From the styles I've seen, ribbons and pucks seem like the two most common technologies. Sometimes the pucks have feet that extend off them, but then you have multiple points of contact you have to adhere to the foam board, but whatever, if it works. Anyways, this might be a rabbit hole that you would get a kick out of, and have some great speakers when you're done. You can mount exciters to nearly any surface, but the foam board lets the voice coil in the exciter actuate the foam and vibrate it; similar to how a "cone" in a traditional speaker works. There have been some significant tests performed to see what surface works best, and the foam boards are cheap and very functional. I've actually bought a handful of bluetooth speakers that use this technology, and it's pretty amazing. Even tiny exciters can make hard surfaces bump.

Hook it up to some really good home speakers that will either shine, or reveille subtle flaws. I use either some Yamaha ns1000s, or JBL Summit. I compare everything to my Krell ksa 250 or a very old Russian tubed tube amp.
Thank you for the awesome video, beautiful amp you got there. How would you compare this amp to the Boston Acoustics Gt2300 in sound quality and efficiency? I know you tested the Boston Acoustics several years back and was wondering if you remember the sound quality of the Boston Acoustics as it was made by Mosconi back then.
For my PC I use a Bowers & Wilkens 300 watt powered 8" sub. An ancient pioneer 1000watt home stereo, with a pair of 3" Aiwa speakers, and a Sony center channel speaker with 2x3" drivers. That all receives input from the headphone jack of the tv. The TV is fed an HDMI signal from my pc, which includes the 2-channel stereo signal. My pioneer uses dolby technology to let me hear voices through the center, and music through the right/left main speakers. I live in an apartment, so I can't shake the walls much. When I watch sci-fi movies it does shake the floor. Since I have the free back-channel on the amp for another pair of speakers, I'm curious what exciters would sound like hung from the ceiling..
It does rated power, but really doesn't seem to have a lot to offer after that, really not a lot in reserve. Even tho, with the Rubicon's and other quality parts, I bet it does sound fantastic.

A good class A amp, really high quality output and input stage, glass epoxy circuit board, high quality parts , proper heat decipation beats Class D
Cutting into that Honda powered Ford money with this one Big D! 🤣
Can you please do an amp dyno and Review of the Alpine KTP-445U power pack 4-channel amplifier? I believe it does more than it says.
Go Derek
Pretty amp, and pretty cheap for a class A/B amp. D'Amore Engineering and Sinfoni amps are $8k-13k.
I like your tests / watch them often ...
Do you know if the "Amp Dyno AD-1" can still be purchased ?
I asked "D'Amore Engineering" several times via email but got no answer ...
That's a beautiful piece, for open show.. and. SQ systems.
Nice power and a beautiful looking amp and love the size. It would hurt my feelings if someone had this sloppy just hooked up in a trunk instead of car show quality installed
Beauty of an amp, hope you get your hands on teh 1500.1 or 3000.1 at some point when they start shipping.
Best amp I've ever seen...
1:48-2:00 The most satisfying ASMR I've experienced ever.
She's big and nice looking. Btw still waiting on the do it bump doe shirt.
I like that blue.
About the oversized speaker terminals. I assume.
Imagine running your front stage with this amp. And its allll the way in the back of a station wagon, or some other long chassis vehicle. Which i think Stereo integrity acttualy did for one of its demo cars. Big gage speaker wire plus looong runs. No voltage loss or signal loss. 👍
What a gorgeous amplifier. Reminds me of expensive audiobaughn. Looks a little like my TRU amps. 👍👍
Im just finishing up my truck(2dr Ford f150 2010) build with all the old stuff I had. Rockford t2 6.5 and t1 5.25 in the doors running off old alpine mrv-f300 which i need to replace,
these are 4 channels im looking at.

I want a stereo integrity SIQ 200x4 for my front midbasses and subwoofer, and SIQ 75x4 for my wideband drivers and rear mini coaxials in my SQ system. As well as a Helix 6 in 8 out DSP for my SQ needs.
The plastic peal 🐬
Excellent video
This amp is great for a processor or component speakers NO Xover!
That Pullin that protective tape off the glass was soooooooo satisfying to watch.. BEST PART OF THE VIDEO!! IMHO.. thank you Derek... 😊
😬
When you where pulling the plastic off of the amp, I felt like I was watching Rhianna dancing
I guess that's a good thing...
Did he say $1299...whoosh! 🤔 Looks amazing

288 x 4 to the midrange whewww!
Hook it up to some really good home speakers that will either shine, or reveille subtle flaws. I use either some Yamaha ns1000s, or JBL Summit. I compare everything to my Krell ksa 250 or a very old Russian tubed tube amp.
Thank you for the awesome video, beautiful amp you got there. How would you compare this amp to the Boston Acoustics Gt2300 in sound quality and efficiency? I know you tested the Boston Acoustics several years back and was wondering if you remember the sound quality of the Boston Acoustics as it was made by Mosconi back then.
I love that Boston amp too. I doubt you’d be able to tell a difference in SQ, honestly
Has the T03 transistors like Tru Technology , Mmats, and Linear Power.
TO3 is just the casing, not the transistor itself. I was corrected before, just sharing the info love 😎
Holy crap that's beautiful!
For my PC I use a Bowers & Wilkens 300 watt powered 8" sub. An ancient pioneer 1000watt home stereo, with a pair of 3" Aiwa speakers, and a Sony center channel speaker with 2x3" drivers. That all receives input from the headphone jack of the tv. The TV is fed an HDMI signal from my pc, which includes the 2-channel stereo signal. My pioneer uses dolby technology to let me hear voices through the center, and music through the right/left main speakers. I live in an apartment, so I can't shake the walls much. When I watch sci-fi movies it does shake the floor. Since I have the free back-channel on the amp for another pair of speakers, I'm curious what exciters would sound like hung from the ceiling..
A 1000 watt home stereo? To cool, myself and others I'm sure would dig more info on your pioneer, share more,. Thank you
Oooh so pretty 🤑🤑🤑🤑 Those shiny copper cap covers are nice looking
If you tested both sides it would have given some insight into quality control and maybe component matching.
Stereo integrity won't be a company to worry about with that.
This seems too beautiful to even go into a car.
It is a work of art
You should try out a Rockville db16 and see how it does 👍
Ive been wanting this amp and do a blow thru box with the stereo integrity 21in subwoofer in my f150
Gorgeous
You know what’s funny. Those 63v caps are used in my slot machine power supply!
Good memory, or you were recently working on it... :) haha
@@volvo09 working on it now! They are not the easiest to get parts/info on.
Is there a capacitor needed if i use the 1500 watt amp with the sql 15 woofer on my audi a4 b8 without a 2nd battery ?
It does rated power, but really doesn't seem to have a lot to offer after that, really not a lot in reserve. Even tho, with the Rubicon's and other quality parts, I bet it does sound fantastic.
Sounds fantastic to me
It did like 30% over rated power at 4 OHM.
Missed this one. That is a surfboard. Nice looking amp though. I wonder if that design is an old school A/b amp. The components look like it could be.
Dats a beautiful amp, great show bi d
Thanks for watching and commenting!
So nice amplifier looks so good
Would love to see a sampling of the eventual uses for that pine box. I know what I’d use it for.
