Then I truly doubt you ever had the opportunity to use one for a long period of time. You really can't judge one in a music store for a few minutes of playing. No other preamp has the Aphex circuit and nothing sounds like it.
You're right that nothing else sounds like the Aphex - but *I* don't think it sounds as clear and as real/organic as the LR Baggs preamps... You are wrong in stating I haven't checked one out, because I have - IMO, the LR Baggs preamps I showed are better, and the Dual Source setup I listed is FAR better than any of those...
