Hope some AK member grabbed the Classe Sigma Amp2 I saw at a local pawn shop a week or so back. Knew the quality of the brand, no idea about the model. Looked like new. Specs on back panel were cryptic. Did a bit research on it. Wow...! Asking price: $550. Kicked myself in the rear today as of course, it's gone. Would have loved to try it here as a stereo amp with my Kappa 7s.
