Indestructible really indestructible: in 10 years I just resoldered the fan. The sound is very clean. Good reproduction of the vote, a sharp hair highlighted (just the correct equalizer) and the bass is firm with good sitting in the low frequencies (depending also on the quality of the speakers: a set; should not be put behind boost).
Of course there are better or amplifier to power subwoofers: MA crown, but much more expensive (damping factor of 300 is good but a bit just to amplify boxes). It is very good for pregnant broadband.
The system ddt (destructive distortion) limit built into the amp very well by reducing the gain when a clip has been detected as long as the mixer is not in continuous ultra red zone. It is the user to have the "presence of mind" to reduce the gain.
Also the fact that the knobs are on the back prevents other people who love the thrill to touch (it avoids the case of the material: it is not so bad when it's in a rack).
However, the only small downside was the audio input in the form of Jack and output in the form of block (nothing too serious).
At the time good quality / price ratio. Today the same report is even better.
With experience, I do it again this choice. I will remain in the range Peavey (or crest audio products themselves) that is very musical to me (big brand experience among musicians: guitar amps, speakers ...).
I put 8.5/10 because it is a very good amp.
