450 Pound Monobloc Amplifier

i was told many years ago in audio that if you bought by weight alone you could never go wrong

Tomtab, a lot of people were told the world was flat, tomatoes were poisonous, and the mean old lady that lived in the big old house across the street was a witch....did it ever occur to you that whomever told you to buy amps by weight alone could be wrong? The operative phrase in your post was 'many years ago'. A lot has changed and improved since 'many years ago'. The 21st century is here and it's moving forward with a vengeance. I currently have huge monoblocs in my system, but I'm certainly willing to...and will explore this new switching technology. I have nothing to lose if it doesn't pan out...and a lot to gain if it works out.

Tomtab,
You wrote"I don't care how good they sound" here's where I'd disagree. All that would matter to me is the sound (what else is more important).I believe quality transformers and linear power supplies are crucial and will produce superior sound compared to the newer light weight amplifiers. If I'm proven wrong then that's fine and represents progress(no problem admitting that). I've yet to be persuaded based on what I've heard so far.I prefer lower power simple circuit amplifiers built with premium transformers and very stiff power supplies, this means increased weight. The final verdict is sound quality, which ever technology sounds best is what I'll own.when the light weight amplifiers sound better to me than the traditional approach, I'll happily buy one.

"i was told many years ago in audio that if you bought by weight alone you could never go wrong.i guess im old school."

Tomtab,

I, too, would recommend you use your ears when choosing an amplifier, not heft.

I hope you're not using this old school method when choosing a wife or significant other. Choosing a mate by heft could result in poor choices.

Sorry Tomtab, but I couldn't resist, no offense intended.

your right charles, when the new class d amps sound better,i will buy one

are the class d amps able to drive difficult loads into say 2 ohms. the big monster amps can put out power into 8,4,2 omps without breaking a sweat. thats what im concerned about. sure, a efficent speaker into 8 ohms,no problem. but what about a speaker at 86db, 4 ohms or less. is a 15 pound amp going to have the stiff power supply to get the job done. my weight alone comment was that you were probably going to get a quality piece of gear if you ended up with a heavy piece. not that the heavest piece was the best. hey,come on. some guys like brawn over finesse.
