I've been spending some time reading about tuners on www.fmtunerinfo.com and have learned quite a bit more than I thought I knew about them (even bought myself a nice Marantz unit that beats the heck out of my receiver's tuner).

Anyhow, I was wondering if there was such a site for preamplifiers. I realize there are a lot more preamps than tuners out there, but it certainly would be a tremendous resource for the audio community.
