Bi-amping????

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.

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
David

I take it that active biamping is better because it is less work for the amp because is not having to reproduce full range?

Would you need a certain Pre-amp with that capability?

I appreciate all you guys help, many questions have been answered.

Thanks Again

David

Thanks for the heads up on the power wires.

I will have to purchase a electronic crossover before I bypass the passive in speakers, Any ideas on a good one???

I really appreciate all the information you guys have provided, I am not very educated on terms, so I quess it was hard for me to describe what I was trying to accomplish, but you guys interpreted well.
Thanks Jim S, Whoaru99, electroid and greg, I will post on here again after the holidays when I get everything set up.

Also any suggestions on what guage power cable for the nad's to replace stock ones?

BTW....I bought the first NAD2200 on ebay for $200.00(great deal I think)but Looks like the 2nd NAD 2200 amp deal is falling apart(here on audiogon) You guys know anywhere else to check for a 2200?

Or is there another model NAD amp that I could purchase That would work better for 2nd amp?

I have heard biamp setup before and had one years ago(mono blocks, Personally I feel there is a drastic improvement to dynamic range, and all around sound is superior. I think I am going to leave speakers alone and just use biamp setup with pre/amp and transport.

The reason I question the power to the speaker is because Reproducing musical signals, the NAD 2200 routinely delivers over 500 watts per channel into typical
loudspeaker impedances the 2200 is a very conservatively rated 100 watts/channel power
amplifier that has an extraordinary +6 dB of dynamic headroom, meaning that it can produce more than
four times its rated power during musical transients.the unique PowerTracker control circuit
(patent pending), which automatically adjusts the amplifier’s maximum power output according to the
dynamic character of the signal that is being amplified. As befits a product designed for the
reproduction of music, the NAD 2200 achieves its maximum power output of 400 to 800 watts per
channel when amplifying wide-range musical signals that contain peaks IO to 20 dB above the average
level. But when the amplifier is fed a high and constant signal (i.e. a sine-wave test tone instead of a
musical waveform), its maximum output automatically declines to avoid overheating, and eventually
levels out between 100 and 200 watts per channel.

As far as the power it has two power supplies, switching to the
high-voltage supply when maximum power is needed, and switching to the lower-voltage supply for
cooler operation at average power levels. (The switch is called a commutator; hence the name for this
type of amplifier.)

What is the difference between passive biamping and vertical?

Only information I have on the Paradigm monitor 11's is that they are"compatable with 8 ohm". The crossover built into the speaker is 3rd-order electro - acoustic at 2.0kHz; 2nd order electro - acoustic at 600Hz (lower bass drivers).
On the web site jim mentioned( sound.westhost.com/bi-amp.htm) they say most common question I get is ...

"Do I need to disconnect the passive crossover in my speakers?"
The answer is ... Yes, otherwise you are not really biamping at all.

If this is true then you literally straight wire your speakers to the terminals? taking out passive crossover in speaker? If so then do you use electronic crossover with same frequency as passive(out of speaker?) and where do you run the electronic crossover? before power amp?
