Alto Professional APX1000

I boought this power amp to replace my very old Peavey CS 800, a channel went out plus other problems. The Alto is Class D which is light and easy to use. I have band rehearsals here every week and it is necessary. The sound is clean and clear at any volume and it never gets hot. Very quiet running. If I were to buy again I would opt for more wattage. I only use mic'ed vocals through the amp via an Alesis (Alto) 16 channel mixer which is on par with a Mackie VLZ. I have the amp volume maxed at all times and it has never reached clipping. I have never had any problems with Alto products.
