Are Rotel amps and preamps any good?

What exactly is "lacking" in Rotel's preamps?

Someone once said, "Rotel designs their products from the outside in."

To my ears, Rotel has both good and bad traits:

THE GOOD:
-Very good build quality and attractive looking faceplates
-Crystal clear and sometimes "glass-like" clarity
-Hyped up detail
-Soundstage is very forward, like you're in the front row

THE BAD:
-Voiced to sound dynamic (can be good or bad depending on perspectives)
-A bit too forward in the upper-mids/treble
-Not enough wamrth
-Bass is lacking in texture and definition

Another area of bad is that all-in-one Rotel systems are usually set up with B&W speakers. Depending on the B&W speaker demonstrated, it can bring out all of the negative traits in Rotel.

Pair Rotel with speakers on the warm side, and those without metal dome tweeters.

Initforthemusic, what did you find negative about Rotel preamps? I've read for years to avoid their Pre's. But I have never found out a reason why.

Is it sonics? Poor reliability?
