Muataz
100+ Head-Fier
This is a new Headphone Amp/Preamp fully discrete resistor with superb measurement ( The cleanest ever ) ?!
At maximum output, SNR and DNR are 147db.
When outputting 50mv at low gain, THD+N still has -96db @1khz A weighting 20-22khz.

It can output
16Ω 10W
32Ω 5.5W
68Ω 3.1W
120Ω 2.0W
****************************************************************
UPDATE:
The Class A mode of the SA-1:
In Balanced 16 ohm load: under 500mw;
32 ohm load: under 1000mw;
68 ohm load: under 3000mw;
Load of more than 68 ohm : almost all the power is class A.
****************************************************************
It has Low-Z / Hi-Z Headphone output impedance switch ( 0.7 Ohm to 11 Ohm )
2 Gains which can be switched from the bottom of the unit. ( You have to turn all 4 switches on the bottom)
The following is the maximum input without distortion at the maximum volume. no load:
low gain: XLR 15.5VRMS,RCA 7.4V RMS;
high gain : XLR 4.4VRMS,RCA 2.1VRMS.
When there is a load, it is about 10% lower.

I got mine this week and I liked it so sooo much, I'm waiting for my other amps to come to compare it. I have DAC Aeon and Focal Clear pro to test it with.
I open this thread to get any feedback from anyone brought this amp, I have feeling this amp will be a big hit as it measure well better than THX amps and based on discrete design and can function as Preamp
