Thanks for your comment, Joe. I had considered the possibility of waiting for the SIT-3, but I decided that it wouldn’t be suitable for my purposes.
One reason being its VERY low gain (spec’d at 11.5 db), which would make it a non-starter for my system.
Another being that its power capability (spec’d at 18 watts and 30 watts for 8 ohms and 4 ohms respectively) is probably marginal (or worse) with my speakers, when listening to the many classical symphonic recordings that are in my collection that have been engineered with minimal or no dynamic compression, on labels such as Telarc, Reference Recordings, Sheffield Labs, Chesky, etc. In fact I might not have purchased the XA25 were it not for John Atkinson’s measurements which indicated a maximum power capability (presumably after leaving class A) of 80 watts and 130 watts into 8 and 4 ohms respectively. (My speakers are spec’d at 97.5 db, with a nominal impedance of 6 ohms, and are said to be close to that impedance throughout almost all of the frequency range).
Best regards,
