biamp without snaxo, is this possible?

Ys,

It works with a hi-cap. I have 2 power amps running all the time. I believe it should be the same with a FC. If both sockets run both channels it will work. You can test this by swapping your 150 from one socket to the other.

noel,
thanks for your reply!
that's a interesting news, my only concern is that if the timing between the two amps could be matched, is this an obvious improvement from one amp to two amps? what is the catch?(except the money for another amp and cable)

No problems, you can do it with your FC2 (you can even triamp, but..)
The result varies with speakers. It is generally an improvment. But IMO, a 200 is better than 2*150.

thanks manu and james, maybe I will borrow my friends' amps to test and see whether a 200 or a pair of 150 sounds good in my system.....I hope one 200 will do the job cos a 200 is cheaper than I add an extra 150....

What's the point of bi-amping without going active?

I found that with two power amps in tow, the magical talents of Naim viz timing, coherence, intelligibility, went south, but round earth attributes like slam, weight, etc. became more obvious.

IMHO, unless active operation is on the agenda, then a (single) bigger amp give better results for the money

I agree with you guys, I said:
"It is generally an improvment. But IMO, a 200 is better than 2*150."
IMO, this can be generalized to any Naim amps. 1 amp betters 2 lesser in passive setup.

Chaps,

I have recently biamped two 250's with great success. I have tried wiring them as 125 (ie only one channel on the 250 used) and wiring them so one amp does trebble and one does bass (my speakers are two way).

My findings are that biamping does improve the sound over one simgle amp. Although the loudness does not change, the powerof drums / bass etc is noticeably increased. Detail is also increased as is the overall presentation (presence improved).

I have gone for one amp doing trebble one doing bass as I found I enjoyed this set up more. It also lends itself to an upgrade to active when funds allow.

When I initially tried the preferred setup I had trouble with the cable orientation. I then discovered that one of my 250's is wired wrongly. Instead of channel 1 doing left speaker it infact did right. Once I swapped the cables over the disjointed sound was solved.

I also tried the 125 setup with biwires as my speakers allow this. The sound improved over one sinle cable.

Hope this helps.

Regards

I've dabbled with this in the past, using a pair of 110's. The result was initially impressive, but soon showed up some flaws compared to using just one 110. The answer was to convert the 110's to mono operation - this really was an all gain no pain move.(As James will find out very soon)

Mr. Tibbs,
how to convert the stereo 110 into a mono amp? please tell us more

James,

Only you can decide if equipment upgrades are good or bad in your system (its clear that we all hear things differently). To my ears the 250 biamp setup give greater enjoyment than one. I feel that the sound is a bit nearer to a live performance sound (which I am trying to reproduce).

The biamp setup allows more of my CDS / 52 front end to shine through.

Regards

Chris
