Bi-amping????

Certainly, if the speakers have 2 pairs of input terminals. Some will tell you that this kind of passive biamping does no good and isn't worth the price of the extra pair of speakercables, but it's certainly worth trying.

BTW it's 'biamping', with no hyphen.

Thanks,They do have 2 pairs of input terminals, I have waited on my children to get older before I started a 2 channel system again, I can't afford tube mono blocks So I see I have the chance to purchase 2 nad 2200, I started thinking why could I not use them that way. But I did not want to melt them down so I wanted someone who knows more about it to give me their opinion.

What you are describing is vertical biamping. Take 2 identical 2 channel amplifiers and use one channel of one amp for low frequency output to a certain speaker and the other channel of that same amp for high freq. to the same speaker. You mirror the setup for the other speaker with the 2nd amp.

If my thinking is coherant today, you either need to have 2 preamp outs from your preamp (2 right channel outs and two left channel outs), or some way to bridge the amp input signal to both channels at the amplifier (some power amps have this capabilty with a jumper or switch), or you will need "double terminated" (there is a proper term for these) interconnects from your preamp to the power amps.

Even passive biamping made a tremendous difference in my system compared to using the stock jumpers or a biwire setup. I have Magnepan 1.6's (hard to drive) with Arcam Alpha 10 amplifiers (modest power of 100w into 8 ohms).

It is definitely worth a try. If you think it through before hooking everything up you shouldn't do any damage. If you turn the gain all the way up, there is no guarantee that the speakers will handle the load though. That is a different question.

Thanks for your help jim, I purchased a nad pre-amp/tuner 1600 on ebay item #250060026348, and a nad c521bee cd player. I will not receive the pre-amp until the 28th. You described exactly what I am trying to do, although i am not sure if the pre-amp has 2 pre-out outs, but if it does not then I assume I will have to make some sort of 2 into 1 split to run to each amp. I am jealous, I too once had a set of maggies with jolida tube mono blocks and I sold them in the early 90's(wish I never had) The sound was very sweet.

I am curious however(may not know what I am talking about here) when Paradigm says 15-150 watts 180 max. does that mean bridged. Another words when I hook up high side from speaker to one channel on amp and Low side on same speaker to another channel on amp that is continuous 200 watts to speaker, I know it is not going to same speakers with-in the speaker but that is not too much for that rating is it?

Thanks
