Crown commercial amps for home use?

The K-1 is decent, but overpriced... Definatly do not buy a FAN type of any pro gear they are loud, and 99% of the time have a slight ground hum even if you lift the ground, and really only sound decent with Subwoofers. The other problem I had with my stint into pro audio amps is that you will need a Rolls line convertor as pro audio amps are designed for a 4 volt input source and if you run a commercial preamp or most Cd players which are only 2 volt into it you will not get full range of output as you will be underdriving the input by half, also the Rolls convertor piece gives you RCA input and XLR output which is what you need for many of the cases converting commercial gear to hook into pro gear. These devices cost about 50 bucks on a deal online, but I suggest against any of it unless you can go to a Local guitar center or something and try out the K series for yourself, It might be the ticket, but I still think very overpriced in comparison to some of the better used gear you can grab of higher end manufactures.

I had a Ce1000 myself, very noisey, I have not tried QSC so who knows it will come down to system synergy in the end, if you can save a lot of money and make it work go for it, but I still go against Fan type even if they are quiet enough, all kinds of build up will get stuck on it and ultimatly could fail and you would not no about it until it overheats, not saying it will but more moving parts in the signal and drawing power for devices that can contaminate your AC line without being involved in the music the worse it is in my opinion.
