Accuphase: Bridged or Bi-amped P-4100s Vs P-7100

Trying to get some comments based on experience. The question was placed in another thread I initiated a couple of months back.

I am about to get my Accuphase gears. I have been toying with an idea. How would a pair of P-4100s in Bridged or bi-amped configuration perform compared to a single P-7100? Price-wise they (P-7100 and two P-4100s) are pretty close. Bridged with P-4100s, there will be a lot of power muscle, but will there be any deterioration in sound quality? Shall I be able to get the sweetness of music Accuphase is reputed for? Has any other Audiogoner tried this?

My current equipments are:
CDP – Audio Aero Capitol
Power Amp – Bryston 7BssT mono blocks
Speakers – PMC IB2 and Usher BE10
Interconnects: –Accoustic Zen Silver Reference, Matrix Reference
Speaker Cable – Accoustic Zen Satori Shotgun

Another idea! A mix and match bi-amping scenario! If I retain my Bryston 7BssT mono blocks and use them as Bass Amp and use Accuphase say, A-65 for mid and hi frequencies, how would they sound? Did anybody try such a mixture of amplification?

No experience with Accuphase, other than having heard a couple.

Have bridged Plinius and it did change the character only slightly, to be a bit more authoritative.

Bridged over biamped easy. Neither speaker looks to be a tough load for an amp rated for 1000W @ 2 ohms in bridged mode, although the PMC's complex crossover could be a mystery.

Besides just being mas macho, monoblocks allow shorter speaker cables.

Compared to the P-7100, the P-4100 has much less output transistors for less of a "chorus of voices" (3 parallel vs 11) and a 950 kva transformer as opposed to a 1.5 kva. Both are fully differential.
