I use it for some years.
I therm class quality of sound well above a 120 or 240 servo Samson.
(Okay this is not the same or the same price range but it's just good to give a comparison with what exists on the market).
* Jack 6.35.
* Screw terminals.
* 2x 35W RMS / 2x55W RMS 8ohm / 4ohm
* S / N Ratio 106 dB (excellent !!!!!)
* Rponse in Frquence: 20 Hz 20 kHz.
I will have AIM slightly more powerful, but it's more than enough for listening to proximity.
His greatest quality and it is normal for a studio amp, is to make no noise potentiometer bottom.
His biggest default is to remain quite rare on the second hand market.
It is indeed an ideal companion NS10M Yamaha.
If you find a good price, DARK !!!!!!!
