AbVA's DVA M750 poweramps are in The Absolute Sound's Editors' Choice again this year.. Since I'm still looking for that magic combination of poweramp qualities for my big SoundLabs, and after talking to Adam at AbVA, I ordered a pair today.

A few things that convinced me is that ALL their powersupplies are fully regulated, that this 750Watts/8 monoamp weighs only 33-some pounds, and that it draws only 48 Watts of power at idle (compared with the 375 each that my Pass XA60.8s draw.. I hope they sound as good as they spec.

Congrats.  You are going to love them.  They will sound different than your Pass for sure.

I Love my M750s with my Magnepan 3.7is.  I've had them for over a year and have had no inclination of changing them.  I hope you get as much joy from them as I have!

The more I think about this HIGH-power amp weighing only 30-odd pounds, the more I don't understand how this can happen.. How can a NINE-HUNDRED-Watts-into-4Ohms amplifier weigh only half (or even less) than the competition's amps?

Hello, AbVA people!!!

And don't misunderstand--mine are still on the way, and I'm really looking forward to them.

It's a good question. My set 500 stereo amp weighs more than that at 250 wpc with the answer being massive heat sinks and a large toroidal transformer. But I have different questions like how can a relatives large amp like this produce so little heat, but it does. It seems AVA has some kind of design magic going on that most other companies don't.

The pair of M750s arrived yesterday, Wednesday.. They were nicely packed, with each carton weighing 40 pounds.. That means each amp weighed about 35 pounds.. They were smaller and simpler-looking inside than I expected, but I'm used to modern amps being crammed with stuff.. Listened a bit after a few hours on them and they sounded plenty OK; I'll be running them 24 per day for many days.

So far, so good.  🙂

Next-day note--they've been running overnite and this afternoon are so cool to touch, one might question whether they're turned on...but the music tells.. I sure hope they end up sounding better that that miniscule amount of output-transistor bias suggests.
