There's a Threshold S 500 Series II for sale here on Audiogon now. I highly recommend that model for use with your Thiel 3.5's. If you really want a c-j, IMHO the MF 2500A is the better c-j.
CJ MF2300A- What's a good price?
I've been keeping an eye open for either Aragon 8008, Classe CA201, or Threshold S300 as an upgrade to the Adcom GFA-555-II to power my Thiel CS3.5s. I believe these are all in the $1000 +/- range. I've got a firm lead on a minty CJ unit--MF2300--bought from a dealer and upgraded to the "A" version and it is local. What would be a fair price to offer for it? How would it compare to the other units I'm considering?
