Best Sounding Passive Preamp


What is the best sounding inexpensive passive preamp? I may have to send my preamp in for repair which could take a while and I don't want to be without music. My top priority is sound, but I don't want to spent a lot of money as I will be putting my preamp back in system upon return. Help please.

The DIYHiFi Django AVC (Silk autoformers) I'm using is the best passive I've tried - including 3 transformer based units and a couple of "pots in a box" (built my 1st in '85). Does VERY little to the signal and is very flexible in its utility. It's a keeper!
Doak, have you tried anything with the Slagle autoformer? I noticed I preferred the Slagle AVC (Bent)to the S&B MKII (K&K TVC). Funny that John at BENT switched from S&B to Slagle due to S&Bs actions, but I think it was also made for a better (relative term as both were excellent)sounding piece.
Folks, just curious, are you trying to help the OP who posted 10 years ago or you just need a reason to talk?
If you want the Very Best the Townsend Alagri is the one to get. One of the best products OF ANY KIND that HIFI Critic has every tested. In another price range altogether. Yes I have one and use it with my CJ 350 or Gamut 200. WHAT EVER you are using now this will be better. I also have Audia Flight and custom tube pre and this is the one I use!
