2 Pre-Outs?


I have a high end preamplifier (which has 2 balanced pre outputs) connected to two stereo amplifiers, both J. Rowlands 112's. Each amp is connected two a pair of 8 Ohms loudspeakers with fairly equal efficiency ratings.
When I play a source (digital or analog) both loudspeakers lose their inherent sonic virtues, particularly gain. When I play each one individually(by turning off one or the other amp.), each pair performs flawlessly.
Should I increase the gain on the preamp?

Well guys! Call me crazy if you want, but at the present I am running 3 systems at once; yes, 3.
3 Preamplifiers, 3 amplifiers & 3 pairs of loudspeakers.
All the loudspeakers have a different positive as well as a negative sound quality to it.
One system consists of a Jeff Rowland Concerto Preamplifier, A Jeff Rowland 112 Amp hooked to JM Labs 937 BE Anniversary Edition.
The second system is a Jeff Rowland Consummate Preamplifier, a Jeff Rowland 112 amplifier hooked two a pair of Aestheth VI Elite Loudspeakers.
The Third system consists of a Antique Sound Labs Otl 32 preamp (also can double as headphone preamp), a Cary V12i Amplifier (running in triode mode) hooked to a pair of System Audio 1532 Loudspeakers.
All sources are daisy chained thru the systems with Crystal Cable, Loudspeakers use Soundstring Cables.
I am using the 2 outputs of a Cayin SACD player.
I can play each sytem separately or all played at once at different gain levels.
I have failed to notice any Phase problems.
So, call me crazy since it sound like a derranged idea. But I call it Synergistic sound arrangement like in a good and well tempered choir.
By the way, I did not have to spend the money on a pair of Wilson Alexandrias or Grand Slamms and other exotic sound gear.
Hi Dan_Ed:
I am been searching for performance level reproduction (96 dB's without fatigue and stridence) and I think that I have achive room filling sound that is involving, accurate and quite detailed.
Hi Aball:
That is one impressive set up, done with taste, a sense of balance and Musicality in mind.
