This now "old" amplifier is amazingly good. I use it as a home HiFi amplifier. It's connected behind an RME Audio ADI-2 DAC and feeds PBN Audio EPX loudspeakers (91db/1W/1m).. Fans never start even when listening at "standard" volume, but they will as soon as you push the amplifier. Fan speed is variable and both fans don't make much noise, but they are not silent. You might want to replace them (I did not feel the need). I had many amplifiers in the past and this one equals the best I had for a fraction of the price (even when it was new). Beautifully designed internally (better than new Yamaha PX serie) with plenty of protection will keep you and your loudspeakers safe. Highly recommended.

Pay attention to the input sensitivity (+8dBu, i.e. nearly 2 Volts) and ensure your preamp can deliver what's required, especially if you use standard consumer preamp (Domestic gear, with unbalanced outputs, are at a much lower -7.8dBu i.e. 0.316Volts). So you might not get the full power (and maybe won't need it). Input sensitivity cannot be changed. Noise floor is a bit high and might generate some hiss on high efficiency horns. I can hear on my speakers if I put my ear close to the tweeter. I can't hear anything 20 cm away. Gain is fixed at 32dB.
