using different amps for Bi-amping ,any good ?? l

Hi, Having done upgrading my spkr and amps;next thought of Bi-amping my spkr(Bi-wireable).My current amps- all tube Preamp(with 2 set of Pre-Out) and Hybrid Amp(160Wx2).
My question is : How about using 2 different type and different power out put amp for Bi-amping ? Any good ?? (I mean I still have my NAD C370/120Wx2,SS,can be use as power amp;it also has 2 set of Pre-Out socket)
Your opinion and suggestions would be highly appreciated and thanks in advance

You can really tweak the sound of your system using two different amps. A lot of people will put solid state on the bottom end and tubes on the top for midrange and highs. My best suggestion is to borrow/demo to try any amps you are considering and see if you like it or not.

The woofer and the tweeter are very different devices. The driver differences will make any power amp sonic difference insignificant. Select amps for other reasons.

Make sure you have the ability to adjust the gain of each power amp independently of the other.

Biamping sounds like it would be a great idea, especially active biamping, which cuts the IM distortion of the speaker's crossover out of the system. However in my small experience (listening to Linn systems) it is not always the best choice. To my ear, two LK85 amps in a passive setup with Keilidhs did not offer a lot over a single LK140. I conclude that as a general rule, one great amp will make two ordinary amps sound dull. I would put the money towards better stereo amplification first.

IMHO biwiring is for when you have already got an amp that makes you very happy indeed, and you want even more of the same.

Hi, Tobias. I have seen some unfavorable result from B-wiring : said would reproduce less/meaner Bass ,some said the sound is not as coherent as with Single-wiring . How much is truee of these reports? Would like to have your(so as other readers) opinions on these ,please.
Thanks in advance
