Bryston 7B SST2 pair

Bryston 7B SST2 or “squared” monoblock amplifiers.  600 WPC, rack handles.  Still look near new - no marks to my eye.  No issues, just favoring tubes at this point.  They are around 8 years into the 20 year Bryston warranty.  I do not have the original bill of sale, so technically they do not qualify for the 20 year warranty, but a source at Bryston said the documentation requirement is not being strictly enforced (and I have not heard of any reliability issues with these amps).  Shipped in original boxes.  Includes the generic 16 awg power cords shown (which may not be original).  Optional Signal Cable Magic Power cords shown (5 feet) included for another $100.  Optional Signal Cable 4 foot Ultra Speaker Cables (biwire, all bananas) shown included for another $100.  Compare with new current model 7B3 ($13+K). $4300. (I am starting this listing without pictures and will add them later).
