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.
