I'm going to eventually try both myself but please add your 2c if so inclined.
The load is true 94 dB, 10/7-ohm nominal/minimum w/ benign phase angles, a satellite with natural cutoff @ 80 Hz. Power handling about 200W @ 20 Hz.
The subject amps are two Schiit Vidar 2 rated:
Stereo 100/200W @ 8/4-ohm, # of channels driven unspecified
Mono rated only 400W @ 8-ohm
My arithmetic below may be wrong. Two Vidar 2 employed in either mono or stereo/single channel application, 1 amp p/c. In stereo only one channel employed per amp. (Can we approximate the power advantage of only one channel in stereo vs, both channels driven?)
Stereo, 1 channel per amp: estimate 75W @ 10-ohm load (maybe 100+W w/only 1 channel driven?)
Bridged mono: 400W @ 8-ohm or 250W @ 14-ohm (increased from 10-ohm) via a series 4R/50W between Vidar output and the load to improve Vidar 2 distortion spectra. (I presume this load never requires more than about 100W in my application.)
The bridged amp has twice the PS current capacity; each channel "sees" 7-ohm drawing 30% more current than the stereo amp's 10-ohm load. Does not the bridged amp have 100% more current driving 30% greater load for 70% net current gain vs. the stereo amp application?
Bob Carver's latter Sunfire amps had dual outputs: direct-wired posts labeled "Voltage" and posts with a series-R like the one I described labeled "Current." I definitely preferred the "Current" outputs driving a load w/suitably high sensitivity.
