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!

Well; I seem to have ran up against another problem.

Will most of these preamps mentioned alter the sound even in bypass mode? I don't want a timbral shift when listening to my HT; but in another discussion, it was mentioned that most preamps will run through the tubes/etc even in bypass mode.

Anyone have an idea about this? Know of any preamps that pass the signal from in-out on the bypass mode without going through the circuitry?

I thought I posted this yesterday but I'll try again:

The SF Line series has dual paralleled outputs for SE and for BAL. How about feeding the HT L/R outs to one on the OUTS on the SF? As long as the HT pre/pro is off, it should not load the SF running in stereo. As long as the SF is off, the HT output should be fed directly to the other SF OUT and on to its amp.

I have not tried this and I cannot be certain it will work but it may be a solution.

Kal,

Thanks for the reply! I think I need to get my hands on a few and try them out. So far, the CJ PV14l, anthem pre2l, cary slp2002, and the SF line 1-2 all sound good. I need to do a little research on them and see what the processor loops do on each...

I wish Utah wasn't in the middle of nowhere for tube equipment; most of the dealers here give you a blank look and a stare when tubes are brought up. "Why would you want to move backwards in technology?" one of them told me. Uugh.

Is there a reason why you are committed to tubes? I would think one should choose on the basis of sound and auditioning and keep one's options open.

No, not really; I've just heard good things from tubes lately, and really been interested. I supposed I could pick up an adcom gfp-750 and run it in passive w/ HT bypass engaged; that wouldn't add any sonic signature. And it seems to be highly rated....
