SPL - Pro Audio Blasphemy?

A few years back I acquired a pair of Legacy Focus speakers, HUGE! At 200 lbs each and 5 feet tall, they are awesome to behold. But, I found them hard to drive. The specs say you should be able to drive them with any 200wpc amp. And you can, but, I found it lacking, not reaching their potential. So, I took my hi-fi amp. A Forte' 200wpc, and I drive the top half with that, and I bought a used Crown XLS2500, which is about 475wpc, to drive the bottoms. And am very pleased with the results! Now it has slam! But still remains so smooth on top even at higher volumes. I only paid $400 for the used Crown in like new condition, and it saved me from spending $5,000 on a Krell or Levenson monster amp. I may still get a Krell or Levenson monster one day, but for now I'm very happy with this Pro audio amp in my system.

Thank you Kirkus for your thoughtful response on rail voltages, I kind of knew it, but could never have said it so eloquently. And let's not forget safety! A failed component on a 120v rail could start a fire! And a failed shunting cap could knock you into the next room! But I just wanted to add, and to answer Eno's post, that the reason this is in a pre and not the amp is because preamps are traditionally voltage amplifiers, while power amps are current amplifiers. And the voltage on the rails is not as important as the available current.

And based on what you were saying Krokus, upping the rail voltage sure sounds like a good way to increase the cost of a component, if that were your goal as well. Plus after all that high voltage is created, it must be reigned back in before leaving the device or as you say, it would be incompatible with most every known amp. I guess many great designs started by thinking outside the box, so even though I believe it's not a good idea, I will reserve judgement having never heard it.
