tube preamps


are these to good to be true. I have been thinking of adding an inexpensive (under 2K) tube preamp to my SS integrated amp. The very positive audiogon reviews on these lower priced models are everywhere. What am i missing....they seem to be a no brainer compared to models in the 5K range.

Never seen a transistor setup that can match the slam, bandwidth, clarity and body of a good tube setup. There's nothing wrong with setting your sights higher!
You need to make sure that the SS amp you’re going to use is not DC coupled, or you may be looking for some new speaker drivers also.
The real no brainer would be buying a $5k preamp (like an Audio Research, Conrad Johnson, or Granite Audio) used on Audiogon for 1.6k !!!
