Regarding the Audio Note, whether there is a difference or not (I'm sure they sound different); I can't possibly imagine any possible difference that could be worth the difference in price; unless you have basically unlimited assets (the money just does not matter) and you happen to prefer the sound of the Audio Note; which is not a given. I also wonder, does anyone (not a dealer, a member of the press, or someone who works at AN) actually have one of these Audio Note preamps in their home system?
