Have had the new Cary 306 SACD Professional Version player in the system for a couple weeks now. It has several hundred hours break-in, allowing the sound to fully develop.
The new 306 Pro improves on the 306-SACD in several ways. The player has better playback of the low level sound on the disc. Instruments and singers convey more timbre and harmonic detail. The best words I have is that the music seems to have more energy imparted to each and every sound in the soundfield. Ambience is enhanced, the soundstage is very dimensional. With well recorded discs (Reference Recordings HDCDs) the reflections from the rear walls of the venue are easily discerned.
Bass is tighter, high frequencies are very smooth and extended. This player is all music, foot tapping and ear-ear grins.
SACD playback still sounds better to my ears than CD. The high frequencies are smoother yet, more liquid and natural. Ambient cues in the soundstage are more realistic. This player improves SACD playback in every way over the earlier version.
Disc access time is about 9 seconds for CD or SACD from pushing the close button until the player is ready to start playing.
The player has been flawless in performance. Even after continuous play for two or more days, the case remains lukewarm to the touch.
Enjoy the music.
