Distortion - The new speakers (Silverline Sonata II's) are the real deal! I'm presently listening to classical via my Jolida modded 402 tuner, and it sounds better than my old speakers playing CD's. The Sonata II's at used prices ($2500 - 2800) are a very good value.
As you recommended, I purchased some 1960's vintage RCA NOS tubes ($120 from Andy @ Vintage Tube Services). These tubes are definitely a noticeable step up from the stock tubes I was running. However, I still have a hankering for a bit more detail and dynamics. My current plan is to stick with the Jolida for the next 6-8 months, then upgrade to the Ayre CX7e. I can't argue that the Jolida isn't a great value, but I think it does not live up to the standards of the rest of my system. I'm satisfied for now, but will eventually get the itch to upgrade next year, money permitting.
