biamping question

Contrary to widespread belief, passive bi-amping (which I assume is what you are envisioning) will not give you significantly more power, and in fact may give you no power increase at all. See the following thread:

http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1268599000

If you use different amplifier models for the lows and the mid/hi's, you may also have a problem keeping the gains matched, as was stated. And you may degrade the sonics, at least slightly, if the two amps have differing sonic characters.

My suggestion is that you consider simply replacing the VTL's with something more powerful.

Thanks for the help .. i am glad i did not buy the amp yet. i will sell my vtl and get something more powerful
thanks again

That was easy.Talked him right out of that didn't you Al!!!!!!!

And the OP should be grateful for it.

I've got 60w dynaco mkiiis running the tops of my VR4s (89db), and a 170w power amp running the bottoms. The power amp has potentiometers for each channel, which I turn down to a little less than half and keep them there. (You can accomplish the same thing by other means). I've used a passive pre to good effect, but currently have them running through a Juicy Music Peach II. It sounds great, and I love the tube/ss combination. I change the flavor of things by switching out the power tubes in the monoblocs from time to time. No way I'd sell those VTLs.
