I really love the idea of Full Digital Amps - no need for a DAC, fully digital signal path, etc....
What would be even more awesome is if the next generation of this amp would have multichannel....like 2-4-6-8 channel versions to choose from
That would be a huge hit amongst people who build multiway systems and home theater also
Just an idea.... @SMSL-Mandy @SMSL_Liu - Thank you

I don't know if it's already posted, but see the ASR review on the SMSL official website:

I appreciate that they kept @amirm 's caution statement at the end. They could have omitted that...

...and its price $999??
At around the 1000€ mark it's a hard sell in the EU. (I know. It has a DAC, but still).
There are quite a few tried and tested class D units with an acceptable level of support.
Ultrasonics cutoff doesn't bother me at all. Why should we care about what happens beyond 22 kHz as long as it gets there linearly and cleanly? (Ok, make it 24 (48 kHz samp rate) if you must, but it's not absolutely needed)
But analog input issues must be resolved.
As is, this iteration is an unfinished product. Instead of a fan it might need bigger heatsinks/dissipators. A fan can be there for extreme contingencies, but not as part of standard use protocol.

Right, but who is a class a amp for? Oppose to class d. What type of audiophile
A class A amp would be ideal for headphone use. The constant power draw is not so much of a problem.

Others are purists with big pockets and big, expensive, high sensitivity speakers. Get ready for about 50 kilos per each single channel monobloc, power draw, heat, and a stiff pricetag.

Is there any difference in sound between a2 to smsl sa400 ?analog only
The power amp sections of the VMV A2 and SA400 are probably the same. However, the SA400 does not use the digital input, which is the main input.

The VMV A2 analog input signal uses the PCM1804's dedicated ADC chip, while the SA400 uses the ADC built into the Axign AX5689 chip for A-D conversion. This built-in ADC is also used for A-D conversion of digital feedback signals.
I haven't bought these two yet, so I don't know how much this difference in A-D conversion will affect the sound quality.
But I think there is a difference that is worth the price difference.

Thanks for the explanation of Toku. The best different of the A2 and SA400 is the A2 is the digital amplifier but the Sa400.

The VMV A2 and SA400 are interesting products, but they are never bought because of their expensive pricing and almost hidden internal structure. I think it's a very disappointing product.
