Looks great!
Nice measurements, very good components, will probably sound very good

Count me in for a pair (stereo).

Regards,
Danny

If you have the modules already made (in some quantity) delivery time it's not of much importance.
Do you still recommend hypex power supply over standard(read heavy)? If so, would you also recommend capacitor changes in these supplies?
I listened your First One amp at Belgrade Audio show two months ago and It was really enjoying presentation. In what way is the amp at the show( if I can call it a prototype) different from your offering now?
Best regards, Milan.

Hi Milan

Yes I still prefer SMPS over classic PSU, because of some major advantages:
- direct and brutal charge of the main energy reservoir capacitors provides power on demand
- fast no delayed transfer over galvanic isolation by means of 100 kHz square waves
- smaller overall size, smaller footprint, smaller secondary capacitors
- lower weight, lower price, no mechanical hum
- integrated soft start, short current protection, protection shutdown, etc.

Nice if you liked the amp from the Belgrade exhibition presentation, well, present version V1.2 of the First One amplifier is its tuned-up version in all respects, how can I say, pure audiophile version with the best parts available.

Class AB, double die mosfet pair 250 W-16 A continous, each.

THD10k 100 Wrms/4 Ohm only 0.004 %, IMD19+20k 80 Vpp/4 Ohm only 0.003 %, 200 kHz square waves on 4 Ohm, is that looks like PWM to you?

Maximal power is normally presented just before clipping with 0,1 % level. Every amp comes to clipp eventually, it is its natural limit.


Had NC400, NC1200 and they don't come no where near close soundwise, the First One is a very different kind of beast.
