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?

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.
There are lots of great choices out there, and a quick search through the archives will give you a sense of the amps you could get for 1500 or less. I've been very happy with a pair of Will Vincent's ("autospec") restored Dynaco mk iiis, which come in at around 1200. That and a 300 dollar vpc-3 would put you right at your budget. But options abound. Good luck.
