Al and Bombaywalla, it's a shame that only now am I starting to appreciate the import of impedance and phase angles plots. Had I known this before, I would have approached my speaker and amp purchases differently.
As I posted above, even the "mighty" Revel Ultima Salons have roller coaster impedance curves, albeit more tube friendly than my S8s. At least Revel had the curtesy of including in their sales literature advice that their speakers sound best when driven by a high current/high power SS amp.
At this point, I'm standing pat for now. As I mentioned, I switched over to the 4 ohm taps on my ARC VS-115 tube amp. I think the S8s sound less forward because the midrange is toned down. Although the bench test reports I posted on the ARC Ref 150 and VS-115 suggest that using the 4 ohm taps smooth out the FR variations at the amps' outputs, I'm not sure how that translates into speaker output.
My understanding is that the S8s are ruler flat when driven by a solid state amp. Perhaps, using the 4 ohm taps lowers the amp's output impedance (maybe .5+ ohms) enough to smooth out the speaker's actual FR to approach a near zero output impedance of a SS amp. Dunno.
If my wife would let me switch out gear, I'm not sure whether I would flip the speakers or the amp. The S8s are the darlings of the reviewer community, especially because of the Be tweeters and top grade engineering, R&D and QC that goes into their manufacture. The VS-115 also has garnered high grades.
If I was to flip speakers, I probably would opt for the Revel Studio 2s, but would need to also flip for a high quality tube amp, maybe the new Ayre VX-5. Dunno???
