Biamp Low frequecy amp recommend

am right now in the process of adding subs to my vac 70/70 quad 989 system.have arranged to buy a classe ca300 to drive the subs.was looking at classe,older rowlands,McCormack,bryston,any well built powerfull amp with a large power supply.

Eagle amps got tons of grunt as well.

Marsh amps.

by the way what kind of subs are you thinking of?what are your main speakers? and are you going to use an active cross over?are you still going to play your main speakers full range?are you considering remote sub volume?I looked for a cheapish huge integated amp with remote volume first but all good units outside budget.so settled on classe with audio synthesis passion to control volume,getting up to adjust volume levels every record will be a pain in the butt.if your going active are you using tubes?

Other suggestions are good and I would also add Aragons.

It's might not be as easy as you think to plug in a different amp as you might think. There have been discussions on biamping before that should be browsed.
