Horizontal Bi-Amping question

J_k advice is good. But since you already have the amps, why not just do a listening test yourself and determine what sounds best to you. Sometimes different amps can be a benefit. In my system I'm using Krell on the bottom and Levinson on the top. I don't much care for the Krell on the top, it's too harsh. I like it on the bottom end--it has more control in the lower octaves than my Levinson. Most poeple will agree that matched amps are the easiest and least problematic way to go for bi-amping. If you were planning a purchase I would give the same advice--but since you already own the amps--why not just test it yourself?

I am assuming that you are passively bi-amping (whereas I am actively bi-amping), so take my advice for what it is worth.
I partially agree with "abstract7", but I do use different Krells for both highs and lows.
I had first listened to which amp I thought gave the best overall sound, and then used that for the mid/highs and the other for the bass. The result is fantastic!
So, LISTEN, and make the decision based on that.

A simple test to see if the highs and lows are tied together via using a common ground in the crossover would be to disconnect the shorting strap and then check for continuity between the two ground posts. If there is continuity, bi-wiring would be fine but i would not bi-amp.

Something else to think about when bi-amping is the "time delay" factor of the various amplifiers involved. Due to different "lengths" of the internal circuitry of different amp designs, the signal could come out of one amp slighty ahead or behind the signal from the other amp. This would surely affect the perceived "prat" of the system along with dynamics. Since most manufacturers don't even give this spec, it would strictly be a crapshoot as to whether or not two different amps would work out "cohesively". The only way to get around this "problem" would be to use two identical amplifiers. Sean
