Both of these are the latest model and built in 2014.

No problems with these and they are great!  I just upgraded to a system that is probably a small step up (but at many times the cost!).  

The CSP3 is upgraded with Beeswax caps, dual stereo outputs, stepped attenuator and Cherry wood base. It is in like new condition with no marks that I can see. It will come with the original tubes (all strong) and it sounds just fine with these but I highly recommend exploring tube options to get the best sound for your system.

The ZP3 is upgraded with Beeswax caps and Cherry wood base. It is in like new condition with no marks that I can see. This ZP3 will come with the original driver tubes. Two current issue Tung- Sol 12AX7 and one old 12AU7 (not sure but marked Hammond). The rectifier is a RCA 5U4G and regulator is Sylvania OA3. All tubes measure strong and sound just fine but I highly recommend exploring tube options to get the best sound for your system.

I would like to sell them together for $1600 but if no one is interested in the pair I would need to get $850 each separately.

Paypal preferred.

Sorry folks, these are sold and paid for.  For those wondering.

Wow, these sold in 30 minutes practically. That is a great score. I am actually trying to get my hands on both a ZP3 and CSP3 just like these!!!
