Well I didn't ask the right question.
What I want is personal opinion on this amplifier.
I have the technical specifications but dont say how good it sounds. I have the opportunity to buy one NEW. Its in a local store for the last 8 years.
Now there is a lot of technical information but I cant transfer all that information to sound quality. Any engineer here that can express his opinion about this characteristics?
This amplifier has 2, 3 o 4 channels
In 2 ch is rated at 400W at 8 ohms, 650 at 4 ohms, 800 at 2 ohms and 1200 at 1 ohm.
In 4 ch is rated at 100w at 8 ohms, 200 at 4 ohms, 325 at 2 ohms and 400 at 1 ohm.
Current capability 100A peak into 0.1 ohm
Dynamic Headroom 1.5 db
Distortion 0.05% or less
Bandwidth -3db points @ 3Hz and 160khz
Frequency response 20-20khz +/- 0.075 db
Noise 96 dba below 1w, 116dba below rated 8 ohm 4 channel, 119dba below rated 2 ch.
Separation 90 db @ 1 khz, 70db @ 20khz
Damping factor Greater then 100@20khz, 1000@2khz and 2000 at 200Hz
Circuit topology: Complementary throughout amp, input to output. Highest-quality film capacitors used throughout. 8 x 250 W high-speed bipolar devices/ch (total 32); 2 x 3200 VA toroidal transformers w / taps each (1.6 kva/ch); separate rectifiers for each channel, filtered w/ 2 x 22,000 uf caps per channel (=0.18F). +/-55 V power supply rails, each channel. Gain = 29db. Input is ac-coupled; output is dc-servoed to less than +/-5 mV offset; no inductor at output.
19w x 7 h x 24.5 d, 84lb.
THANK YOU
