They gradually resume production and even have a small qty of amps in stock. They also say that other models are coming soon as well.

The amplifier channels will be separate in any case, it's just that here they are made on separate printed circuit boards and not on a common one. But this does not make the amplifier dual mono, dual mono is always an individual power supply.

As I understand, you meant multiple secondary windings. Since the primary winding is connected to the mains and always the only one for one transformer (it can have several taps to work with different mains voltages). But the secondary winding is also one here (with a midpoint for bipolar...

Formula S is not a dual mono design, dual mono has a separate power supply for each amp channel, and the Formula S has a common power supply. It would be interesting to compare, because real amplifiers with dual mono like Volot can have a more spacious soundstage. I guess, the Formula will work...

I like Audio-gd in this price point, you can buy even D-28.38 - it's an excellent DAC and very powerful balanced AMP.

And how about Flux Lab Acoustics Volot?

The operation algorithm of such a regulator does not need to be compared by the operation of the volume knob in a conventional amplifier. FA10 uses a digitally controlled relay control, which allows you to select a large number of steps for working with low volume and allows you to precisely...

This is work very good with Susvara, without any distortions or clipping, rich and precise sound, but! FA-10 give a match more - only with this amp, first time in my life I understood why this headphones are so expensive. This amp revealed the full potential of headphones. Now I know - Susvara...

It's a small company from Ukraine, not very famous, but with experienced engineers. I've found tread on this forum about their flagship https://www.head-fi.org/threads/flux-lab-acoustics-atlas-%E2%80%94-totl-all-in-one-dac-headphones-amp-player.897745/

FA12 also better for me - it give reach high-end sound, but FA10 is more precise. Different sound, but for hard to derive headphones of course better choice is FA10, I've tried it with Susvara - perfect!

Absolutely, I've had HE9 few years ago )) Yes I have, I am Flux Lab fun since 2016, my first amp from them Solid One, but now I have Atlas at home. But new FA-10 and FA-12 real great amps. I listened both. So if you want to receive more accurate bass with great speed and textures you should to...

I like Audio-gd products so match, very competitive in that price rage, I have NFB-1AMP (HE-mod). Also perfect amps make Flux Lab Acoustics, but price a little bit higher ))
