Excellent Class A hybrid integrated from Cayin. 80 watts per channel in Class A. High current , will drive any speaker with ease. Preamp section uses two 12AU7 tubes. Original Chinese tubes have been replaced with NOS tubes. Massive heat sinks keep the unit running cool. Unit is never even warm to the touch. One of the best sounding integrateds I have ever owned or heard, think Mcintosh. Balanced and single ended inputs. Tape output. Only reason for selling is a move back to Germany. For this reason I have changed to units that offer switchable voltage. I could almost keep it just to look at it as it is a stunning looking piece of equipment. Rating is very conservative, could easily be a 9. Average Blue Book is $2,000.00. No issues, non smoking house. Pickup in the Atlanta area is possible. Unit is very heavy, estimate shipping at between $125 -$160 depending on location. Audiogon shipping estimate is off by about $10. Unit will be double boxed in original factory cartons. Please see my feedback. Please do not bid unless you have positive feedback.
