Advice Needed...16 Year Old Bryston 7B-ST's or Emotiva XPA-'s (gen2)?

Hello All!  As the title suggests I need advice on what YOU recommend.  I can acquire a pair of 16 year old Bryston 7B ST's (gently used) or a NEW pair of Emotiva XPA-1s for about the same money....I don't have experience with Bryston at all, I currently use two Emotiva XPA-2 (gen2) Bridged in my system and I am mainly a vinyl listener using a Thorens TD-125 Long Base with an Ortofon Cadenza Bronze and a Manley Chinook...My speakers are Definitive Technology BP 7000sc (built in class D 1800w subs) and I bi-wire.  In my "old age" I have come to enjoy a really good soundstage rather than sheer volume.  I am not concerned with warranty at this point although the Brystons do have 3 years of warranty left.  I have enjoyed the Emo's that I use but I am looking to go to the next step.  Any advice would be most helpful.

Thanks!
