Anybody own Audio Experience Symphonies?


Anybody own Audio Experience SYMPHONIES preamplifier from YS-Audio? How does it sound compared to other high end preamp?
royy
I bought the symphonies (not +) 2 years ago and while it sounded great, a local tube gear builder said it leaked DC current - my classe amp kept shutting down. Having said that, it worked with a rotel receiver which did not shut down. It had the cheap EI tubes which I recommend replacing. Build quality was great for price.
I have used Symphonies (not +) with Classe CA-100 amp for almost 1 year. Its performance is excellent. Wide soundstage, deep low and mellow. I’m now considering upgrade my system to Symphonies Plus or BALANCE A1.
The website says they corrected the 'dc leak' problem...never heard this equiptment but was checking their info and thought I would mention they are aware and claim to have fixed that problem.
