I am looking at purchasing some 5 year old 7bsst’s. I know there are differences in the 7bsst’s along the way. Are there any known issues/problems with the 2005 7bsst’s that cause people to avoid these? I believe that at some point there was an output choke update/modification available for the 7bsst’s. What should I look for when considering the purchase of 5 year old 7bsst’s? I own the following Bryston products but have been considering getting some 7bsst’s for some time (2 4bsst’s, B60R, 2B-LP, BP-20, BP5). What would be a fair price per amp if they are in good functional/cosmetic condition?
Any input is appreciated.
