Bryston 9B SST2 - Amazing 5 channel amplifier!. This is such a clean, warm and powerful 5-channel amp rated at 150 wpc. I have the original bench sheet, invoice showing a purchase date of 12/26/2014 from Sound Video in McGregor, MN the original manual and power cord as well as the original box and packaging. It is all boxed up and ready to go. I moved to a new house and no longer have space for a full system.
