When I decided I'd go with a prolite 3.0 I thought I would be in overkill territory. Which is what I wanted, I'd rather have and not need than need and not have. But I have to be honest, in the two rehearsals I had with it before it crapped out I was not that impressed with the volume I was getting. Part of it is the inefficient ampeg 610 or 810 I was playing through, but the other part is class D. When played to the point of power amp clipping, my old 4 pro got every bit as loud at ~475w as the prolite at ~875w. That was pretty discouraging.
I know a watt is a watt is a watt. I also know that wattage doesn't necessarily indicate volume. But I would think that adding 350-400w would still deliver substantially more volume. Now we all know that a 100w tube amp will out-loud a 100w SS amp through the same cab, but my experience is telling me that 500w of heavy lead sled SS will out perform 500w of class D power 8 days a week. Like if I want a lead sled that can compete with an SVT I need like 600-800w. But if I want a class D that can compete with an SVTs 300w I need like 1200-1500 watts. I don't get it.
Am I just reaching the limitations of the cabs I have access to? I don't want to blow speakers, but I find it shocking that I can't find a power supply that isn't pushed to its limits at the volumes I need. Which, while very loud, are not as loud as many bands that we have all seen.
If someone has any clue ins for me in laymans terms that would be killer. My two 100-120w tube amps are enough(louder than my power amp running 875w a side), but I'd rather not risk their welfare as I intend to keep them for a long time.
