It was the CDP-XA7ES, but it is not as desirable as the CDP-X707ES and CDP-X779ES. The XA7ES has a really cheap and unreliable transport (built around $15 laser pick up) which is not even close to the one found in X707ES/779ES as used also in the top Accuphase CD players/transports. The only other transports to compare are the legendary "swing arm" by Philips and "VRDS" by Teac.
You can forget about "belt driven's" and "stable platters" with confidence.
