You are not doing the comparison right. It has to be level matched for one. If you did it right, you would learn that there was no difference between the two.

This should be mandatory reading for new members.
Right.
I was once a 'poor guy in his twenties chasing better sound quality', but I didn't really know what I was doing. No shame in that, we all start in this game from a position of zero knowledge.
If you want a big jump ahead, stop chasing better sound quality with the electronics and put whatever money you do have into loudspeakers and room acoustics.
I really wish I had understood that when I was your age but there was no internet then, no ASR where I could learn real knowledge. Take full advantage of it.

I have de Fosi V3's powering 802D3's and must say that they sound amazing, the "pre-amp" used is a Marantz HD-DAC1 tat will be replaced by a Topping DX9.exactly, get a Fosi V3 and live happily, close your eyes and listen! saving 3/4 K of the budget
Close your eyes when listening, otherwise your eyes will influence the sound you perceive.

if such a clone was built to last 40+ years like real accuphase i would prefer to have it over any modern class d amp with unknown longevity/ failure rate.

For how many years a component was built, becomes obvious when it fails
Hello,
Of course, clones will never sound as good as the originals, I disagree.
If you have electronics knowledge, any clone will sound excellent.
A GOOD PCB base (gold)
A well-thought-out design
Sometimes an improvement, even the entire original.
Using good components is very important in Accuphase clones, large projects.
Because they consist of over 2,000 electronic components.
You can't ignore measuring the finer components
because you'll lose quality.
See my assembled project.
Accuphase Golden Voice C-2810 (Nori) clone
How it works.
After assembly. I've had friends with expensive audio systems with the Golden Voice C-2810 and they were impressed.
I'm assembling various Chinese clones and testing them to the limit.
For example, this is the next clone I'm building: the Audio USA CAT SL-1. Its problem is hum and distorted high-frequency response.
The left channel is muffled.
After matching all the capacitors 1-to-1, the high-frequency response is correct.
And after matching and measuring the tubes to match the power, the left channel has practically the same volume as the right.
The next problem is hum. After rebuilding the linear filter
for the 6.3V power supply for the auxiliary tubes, I used 1000uF,
which improved the start and voltage purity.
And I added a five-stage filter to the 270V main power supply. The hum is gone.
Further work is on balancing the XLR.

IF you don't have any knowledge of parts and components from China, and you're building a project with cheap resources,
forget about sound quality... greetings.

My Mumsy E-406 came in today, here are some pictures comparing it to my Galion A75. The
mumsy is crazy nice build quality for the price (475+280 ups shipping)
The Vu meters are very nice and not cheap looking and respond just as smooth as my Vu meters on my n2000a.
It’s heavy, GD it’s heavy.
Packaged extremely well, I don’t know anything about amplifier internals when it comes to quality pcb or parts.

I disagree. Copyright issues aside. It's all about performance vs cost surely?
It looks reasonably well built. (Unlike that car.)
Would love to see it measured. Longevity is my other concern.
Somehow I doubt it will last as long as an Accuphase. You never know tho.

Clones always come with an aura of fraud and desperation. One originates from the con type suppliers the other from the buyers.
Oh geez dude, go touch grass, 99% of people have no idea what Accuphase even is, this was bought for fun.
If I knew how to do it, I would.

Why are you even on this thread then ? If your just here to say how disgusted you are then fk off. Seriously. Go spend 3k on a LV handbag that cost $50 to make. I doubt you could even tell the difference between a good copy or real with bags, sneakers and etc.
+1000 .
You can always study previous art , it would be stupid to do otherwise , when designing amps you look at other amps .
Cloning implies other things .
That there is some special secret sauce that only Accuphase knows , that there is esoteric knowledge and woo woo .
In reality the secret behind Accuphase is Accuphase the whole company ! the way they do everything .
Stealing their thunder is the fraud . We should not bee a part of that it's not "fun" its immoral . A person of low moral standard commits fraud or partake in these schemes by being a customer to the fraudsters .
Believing there is some special secret sound to be had doing this is Audiophoolery ie the desperation part , and these clones somehow unlocks the secret to mere mortals who can suddenly afford this level of sound qulity.
Why don't these con artists invent their own brand ?
I bett that most of the actual circuit design is well known from textbook and good engineering practice and not patent protected or anything such .
Design you own amp emulate Accuphase by doing a very meticulous and high quality design that's very reliable etc a cost no object design. Do a very luxurius exterior and interior to give your product the luxury look too . In fact emulate Accuphases way of doing things but dont try to bee Accuphase .
You can ofcourse also do a modern cost effective design that has exactly the same sound quality as any good design ( transparent to human listeners ).
But then you cant borrow someone else's good name to it ?
They you have to do the work of finding a market niche ?

Easy guys, other members are allowed their opinions too... best to play the ball, not the man/person.
Anyway, thanks for posting all the pics @ryan74701.
