Montana Speakers? Have they fizzled out?

I have a pair of 1yr old KAS speaks. Now I bought these to crank up and not worry about anything(within reason). So far I've gone through 2- Parasound 5.1 amps now I'm on my second Aragon 3005. Everything is bi-wired, $5000. speaker cables and so on. But after almost a song same ol' stuff,Keep blowing fuses or tripping amp to shut off. Very ebarassing when showing off your system. I realize that I turn it up louder than the average bear, but I thought the amps mentioned could handle it. Any suggestions? I feel I need a monster pair of mono amps to get the most out of these guys. Let me know, Thanx. G

I really like to crank it up, the audiogon is ok for home theater only, but that is just me. I do like how the speakers sound. Any suggestions on amps. I'm looking into Peters line, Pass Labs x-600, Krell fcp 400. Are tubes the way to go? Is there a big difference in class A amps? Any input would be greatful. Thank you, Gregg
