Both units in excellent condition. The 3B-ST currently retails at $1890, and the5B-ST at $2670. 17 years left on the manufacturer's warranty. I will sell both for $2200, or the 3B-ST for $900 and the 5B-ST for $1300. I am the original (and only)owner. Have original test bench spec sheet from Bryston (each unit is tested before it leaves the factory), and I also have original receipts for both units. Contact me at firstname.lastname@example.org if interested.
