Good tube preamp w/ HT bypass
I've finally decided to snag an AVM30 for my pre-pro, and aragon 8008 amps for my amplification (or Sherbourne 7/2100 - I bought both, and will sell whichever I like less).
However, I keep hearing about tubes! I don't have any experience with them, but I'd love to give it a try. I've read that by combining SS amplification with tube preamps, I can preserve the bass control of the SS w/ the midrange of tubes.
SO - are there any preamps you can recommend to me to try and/or demo? I need it to have HT bypass, so I can use my HT rig separately from this...
I've read the Rogue Magnum 66 is good... The audio research sp-16l is supposed to be good... And the TAD-150 was recommended to me (http://www.angelfire.com/biz/bizzyb/TAD-150.html) but I can't find any other information on it.
Non tube pres that have been recommended to me are the sonic euphoria plc and adcom 750; but i'm not sure if either would better the avm30.
Oh; budget would be $500-1000, used or new. Thanks for any recommendations!
