Pugs,
For what its worth, I just pulled out my RatShack meter.
Using the CD with the lowest recording level I can think of (Fagan's "Kamakiriad"),
a Rotel 971 CDP (I'm guessing a standard 2V output), a no-gain Superphon Revelation III preamp, CI D-200s (26db) with VSR VR4JRs (89 db sensitivity per mfg), I can get to 90-92 db at full volume (c weighting, slow response, at listening position 9' from spkrs). I don't need it any louder than that.
Using my daughters new Red Hot Chili Peppers "Stadium Arcadium" which seems to be recorded louder than anything in my collection, 90 db comes at volume setting of "15 clicks" out of a total of 23, so this disc will go much louder.
Something does seem fishy with your set-up. Please keep us informed.
Good luck!
