Nazar from S-Audio finally produced a device with a balanced output, but it is no amp, it's a DAC — FIRDAC Mini. It is the best DAC I ever had. Just another plane in terms of authenticity, sounds separation, stage, and ability to evoke emotional response from the listener. Listening to it for...

My headphones from Maxim Kryvonos got tested against Audeze and HIFIMAN. Sorry, it's in Ukrainian only, but modern-day machine translation allows reading in any language... MM-500 vs Arya Stealth vs Final Carbon Mk3.1 (Bionic precursor)

I will call Nazar and ask to reply you. He's been very busy recently due to personal reasons and war related issues.

And once more

Meanwhile, there is a new version Focus 3 which is a major improvement over the previous ones. It has an A-Class headamp now, new custom-made digital filters, and updated binaural mode which introduces fewer changes to the frequency characteristics while retaining its "magic" holographic and...

My beloved Final Carbon Mk3.1 (has the same membrane as Bionics) + S-Audio Focus 3.

As to the FOCUS, I have installed new connectors on my mains cable (Zu Audio Event) and it opened new horizons for me. I've been in a positive shock ever since)
