@rjduncan forgive me for jumping in.
thiels’s are great..I have 3.7s, 2.3, msc1, scs2s. I’ve bought most of the used. And of course my Amps are pretty much 2nd hand.
so all I can say is don’t waste a trip. Get all info and real pictures up front, Check serial numbers, etc. don’t spend time fishing for answers - if you don’t get them go find the next deal.
