I can't imagine that either, but this fella is a pretty seasoned audiophile. By the way, I had the CAT SL1 MKII Ultimate, and I ended up with the Joule LA 150 MKII. Both great preamps and some will love one, some the other. But I have not ever heard anything to knock the amp off it's pedestal - it is simply incredible - power and control to drive any speaker, and finesse and transparency. But this Ming Da pre does have me interested, it is "dirt" cheap by comparison to other top flight pres. Another fella whose ears I most defintely trust has falling in love with an ASL FLora pre, I think it is $3000. If this holds true, there may be some real gems in the Chinese frontier. Again, I have not heard either.
