If you like Cary and can't make up your mind , they make a nice one that has dual outputs - tube and SS ! It is switchable on the fly from the remote and sounds quite good too . Can't remember the model number .
Good luck .
Good luck .
You don't indicate a price range, but if you're looking for something in the $1500 +/- range, check out the Raysonic 128. Well built and tunable by tube selection. Got a good review in 6moons. Their only, possibly negative, comment was it was full in the bass, not bright and not as transparent as the reviewers reference. That issue is resolved by simply changing the tubes! Those traits are more the result of using EH tubes than the unit itself, IMHO.
Call Kevin Deal at Upscale Audio and ask him. Nobody knows tubes better than he does and he has both new and used Carys referred to above. I have had a 308, a 306/200, a 303/300 and currently use a a Cary 306 SACD. I have not heard the Raysonic but I would find it very hard to believe that it would ouperform a preowned 306/200 (digital inputs!! and upsampling) let alone the new 303/300. Cary is a great company and I believe since you seem to enjoy your 300sei that the integration into your system of a Cary CD player to be an easy decision. The 306 SACD is PHENOMINAL!!!!! Good luck.
