Dette er hva Stereophile skrev i sin test av Cary 303/300:
Working through the settings, from nonupsampled 44.1kHz through higher and higher rejiggerings, what was unmistakable with virtually all CDs was an increase in the smoothness and liquidity of the sound: rough edges were definitely being sanded off. But the effects of various upsampling rates seemed to vary from disc to disc. What was interesting was that some discs had a distinct "lock-in" point: I would reach a certain level of performance beyond which the sound would change drastically, becoming dull and colored and downright quacky. On Martin Newell's "Call Me Michael Moonlight," from The Off White Album (Humbug BAH25), there was a remarkable change in the sounda really very noticeable differencewhen moving from 96kHz upsampling (good) to 192kHz upsampling (not so good). But that didn't hold true with other discs, some of which exhibited a similarly drastic sonic change, though at some other point along the scale.
Using the Cary CD player's upsampling control resulted in clearly audible performance differences, and after using the CD303/300 for almost two months, I found that I could work with it to optimize certain aspects of the sounds of many discs. I don't think it's possible to say whether some or all of those differences stemmed from the actual resampling of the digital datastream itself, since the upsampling and nonupsampling portions of the Cary's digital filter address distinctly different analog filters within the playersomething that I believe is true of all such products on the market. Was I hearing the sonic benefits of different (re)processing rates, different filters, or both? For now, there's no way of saying, although the possibilities are intriguing. But overall, and notwithstanding the positive changes I heard in the sound, I generally continued to favor using the Cary in nonupsampling mode, preferring it for what I heard as a more involving and, more to the point, less rhythmically ambiguous musical performance.
