Pro-amps are excellent value with lots of power and obviously , a great bang for the buck. I am using a QSC in an instrument/PA application, however, I really could never use it for HT because, as has already been mentioned a number of times, the fan noise out of these units is just too distracting. The models I believe most are talking about are at the lower end of the price range, however, if you want that amp to be quieter at the same or better power levels, you have to move up the model and price range with that manufacturer and because these pro-amps generally only are available in mono or stereo, with having to buy two or three of these higher end units, it would close the gap considerably in money spent compared to a quality dedicated HT multi-channel power amp.
