Given there was a slight design change within the 14B-SST amp commonly known as the "Swedish choke" if buying used you want to make sure you get the most recent version. I believe this "mod" was incorporated after unit serial # 505 (can be confirmed by Bryston). You can have an older version updated but of course the mod will cost you (around $250) as well as freight both ways so look for a more recent amp.
Also if buying used you want to review Bryston's warranty info on their website. Gear made after a specific date must have the original invoice to ensure the 20 year transferable warranty.
