PS Audio has just introduced a "revolutionary" new product called a Gain Cell. It now inhabits every amp, integrated, and pre that they build and summarily replaced their entire HCA2 and PCA line of products (now I know why AudioAdvisor had those combo deals). You can read about it here:

A Question for you engineers out there (if any still inhabit the board); what is this thing in plain english? The spec's are, for the most part, latin to me. Are they good? Great? Revolutionary? Is a damping factor in the 1000's that important? While I'm sure there is some frippery thrown in, is this technology truly as landmark as the SDAT was (and still is)?

Thanks to Geoffcin for reminding me to read my freakin' e-mail every once in awhile.
