Bi amping my Vonschwikert VR4jrs


I want to bi amp my VR4jr's but have been told that i need perfectly matched amps to do this. Is it possible to run my larger amp 200wpc for the base units, and a smaller amp for the mids/tweets?

In the thread I cited, Albert mentioned Michael Percy at www.percyaudio.com, who could put together the resistors you need.

He also mentions something simple: the Channel Islands Audio vpc-3 Passive Controller. It essentially functions as a volume knob for your Celeste HT3. Once you hook it up (with interconnects--nothing technical), you can lower the output of your bass amp to match the output of your mid/tweet amp, whatever that may be. Once the vpc is set, you can then simply use the volume knob on your pre to raise or lower the volume on the whole thing. You can probably get some good advice from the folks at Channel Islands in any case. BTW, what amp are you looking at for the mids/tweets?
I am not sure what amp to get. Thats the next step after figuring out how to get it done. I am thinking Tube 25-40 WPC. i am very budget minded. any recommendations?
I am bi wired at this point using Audioquest sst solid core. I chose the solid core because it really tightened up the bass. I listen mostly to classic rock and Jazz. although it has great sound now, i am looking for sweeter M/T than i curently get.
