I pulled about 100 lbs of amps from my club rig amp rack, and put these in. Huge improvement in ease of loading. I was running a BGW 8000 bridged into the subs, giving 800 watts. I ran one of these in parallel mono to the subs, giving 500-540 watts. I didn't need more. One ran my tops in stereo, and one ran 2 monitor channels, 2 wedges each. I used a Behringer dual 31 EQ for FOH, which provided limiting and a sub xover. Here's the best part- I ran the amps and EQ's from a 15 amp power strip! I was limiting my output to a couple db below max, but I was probably hitting a kilowatt on peaks. There was no indication of sag. All 3 amps were stone-cold at the end of the night. I'm very pleased.

Looking for something for a practice room, purchased Stupid Deal and did not expect too much. Was very surprised and pleased with performance. Plenty of power for Yamaha 115V pair and sounds great.

    Comments about Alto APX1000 2-Channel 1000 Watt Power Amplifier:

    Excellent power amps for the money. I use two of them in live performance; one for mains, one for monitors. They are extemely clean-sounding, and will run all night stone-cold. Light weight and well-constructed, I expect to be using them as primary power for a long time to come.

            Works great and as a stupid deal of the day it was just what I was looking for at a stupid price. Use it to power a monitor speaker for me and another musician at church worship.

                  This amp seems to be well constructed. Slim design, light weight. Very quiet fan. Lots of power for a little cash. I did purchase the ext. warranty due to the fact that I was unfamiliar with the brand name. Great for smaller clubs or parties. Easily handles 100 capacity and under.

                    I have a QSC GX5 as 'my baby', and the tone from this alto is nearly as good. I bought this as both a backup to the QSC and for my monitors and am BLOWN AWAY with the quality and tone. I was lucky enough to steal this in a STUPID DEAL OF THE DAY, but even for the price of a QX3, it's worth it. I also had a GEMSOUND as a backup, which had a muddy sound. This is awesome.

                    I wouldn't have any problem performing live in a small venue with it. The one feature i wish it had that competitors do is for the volume knobs to have detents to make it easier to match channel levels.
