I was a Cary dealer years ago and this is a nice unit, however you need efficient speakers for best results. I think a fair price for these is in the $1500.00 - $1700.00 range and maybe have them checked out by a tech to see if everything is ok. They might also benefit from a capacitor upgrade. BTW: Your Yamaha M85 has sold for $600.00 - $880.00 shipped and the C80 sold for $200.00 - $500.00 shipped.
Help for a Lo-Fi guy
I have 2 Cary CAD-300-SEI integrated amps I am trying to help a friend of mine get some info on. Her husband passed away, and left these along with some other tube amps . I have done some research online and discovered that these are 15watt tube amps that are best used with efficient speakers , or possibly as headphone amps. I am trying to determine , desirability, possible used price etc. My experience in the audio world is very limited. I am using old Yamaha separates (M85 amp,C80 pre amp) that I`ve had for decades, so any help would be greatly appreciated.....Thx
