I am using a Classe' SSP-25 for my music and home theater, and feel it is a good unit, altho it has a glitch I wish it did not have. Using my Pioneer Elite DV-05, upon layer change (a second or less), the 25 will lose lock, taking about two more seconds to lock on, cutting off a bit of dialog on occasion. I have never read about any other processors exhibiting this symptom, and my friend, who owns an AVP says his does not. Classe' feels this is "normal", but Robert Harley, in an e-mail response, has not experienced this. He states "If other manufacturers can perform this without losing lock, then they all should be able to". I still like the 25, overall. Mike Colwell mecolwell@hotmail.com
