Bi-amp question


Ok... I have recently purchased a set of psb synchrony ones and a NAD M3 amp(180 wpc)... if were to add another amp, say a Rotel RB-1170(130 wpc) for bi-amping... which way would make the most sense to wire them up? NAD for the Highs and Rotel for the Lows? or vice versa???

I would obviously need to experiment with them to see which way sounds best to my ears... just wondering if there were any ground rules...

DACT has a 10k, 0 to -12 dB in 0.5 dB steps, "fine tuning" attenuator that can tame different amps. Easy enough to add series resistance if required (50K for some tube preamps). Inline with the "stronger" amp after the Y. Another pair of IC's, a small project box (Goldpoint?) and a drill, a knob, 4 female RCAs, hook-up wire and a bit of soldering.

Don't try this with pots.
Correction: The "fine" attenuator only comes in single deck mono, so you would need two of them.

With monoblocks, that actually works better with the attenuators close to each amp, in separate enclosures.

Some "pro" amps have adjustable gain built in but it's probably just a cheap pot.
