Alright I ordered a A90D headphone amp. I also just scored some coupons on AI and am ready to try IEMs. Are you suggesting KZ Symphony or do you have another recommendation?

Hello! Thank you very much for your videos. I would like to know in your opinion which would be more suitable for classical and jazz music lovers, this fm300a clone or the dartzeel d5 pro?

Siema! Spoko filmik. Ale jesteś pewien, że MT-45MK3 ma 60s soft startu? Wydaje mi się, że nie ma.

Which iem bass is more deep??

The layout of my system (and especially the wiring) is centered around two monoblock power amps. So, when I got tired of my 20+ year old tube monoblocks needing yearly maintenance, I looked on Ali to find replacements. Although there are FM Acoustics clone monoblocks on Ali, some of them are quite expensive. I came VERY close to buying TWO of the FM300 and using them just to run one channel per side-which I suppose would be the equivalent of the dual transformer single chassis version, and even with doubling the cost, this still would have been a relatively inexpensive option and still fit in with the wiring of my system. But I didn't for the simple reason that my 200+lb speakers require high current (my tube monoblocks were 300+ wpc) and I was uncertain that even when ran in the single-channel mode if the FM300 would have enough grunt. So, in the end, without any previous owner feedback I took the gamble and got a pair of Goldmund 29M 'clones' that have 350 wpc into the 4-ohm load of my speakers. These have proven to be wildly successful and in some ways match or even slightly better my $25,000 tube amps. For a cost of $1800, including taxes and shipping. I got the version with the upgraded filter capacitors (a $200+ option). Before I bought these I went around and demo'd power amps in the local 2nd hand market in the $2000+ price range, and none of these came close to what these 29M clones do. I suppose the price of these are somewhat higher than the amps you tend to buy to review on your channel...but if you did want to take it up another notch, these come highly recommended. BTW I have owned solid state power amps up to $30,000 in the past and while I cannot compare them directly, they are in the same system. And I can say that these amps give up very little compared to them. www.aliexpress.us/item/3256805946236269.html?spm=a2g0o.order_list.order_list_main.85.5fcb1802Szadmx&gatewayAdapt=glo2usa

In one of your other product videos similar to this one you pointed out that there were a set of dip switches that allowed you to switch between 110 and 220 current service. Does this product have a similar set up if I bought it? I’m currently in Canada plan to move to Spain. Would it be easy to switch this between 110 and 240 ?

Can you provide a link please

An other major excellent review !

Fantastic vid thank you

Would you say this is as good over all as I don’t know maybe a Hagel h390 or some other amp people would know?

The cat sweet! <3

is this AMP better a the DartZeel-Clone-Amp or is the Dartzeel Bether?

Nice job, any thoughts on the C3850 clone? It seems a good topology , fully balanced in an out and good layout.

Great videos. Thanks for sharing . Wondering which version on Aliexpress you recommend for preamp of same make/quality but with multiple inputs since i notice a few option, but many have different transformers compared to this one. Thanks.

The average recommended burn-in period is about one week longer than the return period.

Hi! For classical music Ananda Nano (590€) or Arya Stealth(750€)?

Would be interesting if you review the mbl6010d clone preamp with these opamps, if they fit!

Nice review. I agree with the great part of the information you have provided us. After about a year of using them, I am really satisfied with their performance. I bought this model because through several sources I received information that they have an excellent value for money... and so it is. Considering the money invested in the other components; Amplifier, DAC, CD Player, and above all, Music Server, and in the cables used to connect them, these Wharfedale 12.2 are below what the equipment requires... but I’m enjoying them so much right now. When I can invest the money they cost, it is planned to replace them with a KEF R3 Meta, or a Sonus Faber Sonetto II, I do not have space for speakers with a width greater than 22 cm.

My second audio system is very detailed and is also in near field (PC) so I guess I will appreciate the difference. Bought. If it does no work I will show up at your doorstep 🤭

I think its an even better approach to short a 47K 2W resistor between the signal and ground of an rca male connector and plug it into the unused input rca female connectors on your equipment such as preamps, etc.

I recall someone suggesting that plugging up the left and right of whatever position was in use (not all of them) was sufficient.. Have you tried this strategy?

I have Ananda stealth 2 and I m searching for an upgrade, If you have to pick one, these or he6se v2? Thanks

You have reinforced my diy project that i never got around to. Use salvage metal rca plugs sealed with copper tape and maybe some magic pixie dust 🧙‍♂️

Oh No! Now we cant listen without taking care of this audio hygiene issue.....Fortunately theyre cheap 😊

Jimminy Crickets! Thank you! I’m glad I watched this. I just bought a package of the shorting ones but hadn’t gotten around to installing them. I didn’t know not to use them on outputs. That was close!

The sets with the pins are arguably the better buy because they can be used on both the inputs (with the pin fitted they'll ground out any noise) or as covers for the outputs (with the pin removed). To use them - safely - on the outputs just unscrew and pull out the centre pins 👍

What do you think? This amplifier has enought energy for big standing loudspakers? Thanks!

Is this class A or Class AB?

Nicely explained. It is funny how many parts/tools we share together, Tuya Smart Plug, Mini PC, Thermometer, Antivibration legs and number of years in engineering etc. 😊😅

hi, what speakers you use for your auditions of these chi-fi amps? how about the bass from this A1?

Krell outside but MF inside obviously?

Hi, Could you explain your PC to DAC output setup?

Too much BS in today's Hi-Fi

Thank you my friend for youre very good information!🌹🌹🌹

Yes I have a question: 🙂 why not? 🙂 your speaker system here I cannot see how you do this explane and show perhaps mere precise if you like. I only have two ports how can I connect two wires four poles? etc. I think I know but want to be sure. ;-) Burn in: I use a classical radiosender 24/7 it has all kinds of music and talk I think this is most diverse sound and only so when I'm gone and just not to loud so that neighbors don't hear it.

Thanks for the educational info ;)

Hello, I’m a big fan of your channel, and the content is awesome but the views going down really makes me sad. I would love to work with you to grow your channel to grow this channel. Is this something worth a conversation?

I rebuilt my amplifier (Pioneer SA7800) out of: 2sc3519 & 2sa1386 OP 2sc4793 & 2sa1837 Driver BC639 & BC640 (will be changed to 2sc1845 and ksa992f, and some higher current voltage stage will be KSC3503 and KSA1381E) The only advatage that those know is that they have lower Cob, its not 7pf like bc639 and bc640 have, its only 1.6pf on 2sc1845 and ksa992f and those ksc's have 1.8-2.6pf. which means it gonna have lower noise in my prediction, for now i have a bit of noise in this unit which i can hear.

There is also something I have experienced which is that every time I connect a new component, my system always sounds better after 1 day. Maybe like time to settle for cables after a certain disruption.

Thanks for the great video. Burn in is real and I have tested it many times before. The strongest or most obvious effect of burn in is after recapping.

Akliam shope also has muses 02. It is very interesting if they are original and how they sound compared to this one. Thanks for the excellent review.

I kept changing opamps until I got these. I bought two pairs. They are every bit as the video said. No longer have the desire to swap opamps:)

Can you talk abaout bruning in cables?

It took a long time for my A-S1200 to settle in - it went in stages. It had better focus after about 500 hours, but now, after three years, it has gotten smoother, with just a touch of warmth. I’ve noticed the same thing with my Schiit Modi Multibit DAC.
