In the November 2008 review of the Cary CD 306 SACD Professional JA shows a graph with the spectrum of the CD 306's balanced output under a variety of conditions, taken by sweeping the center frequency of a 1/3-octave bandpass filter from 20kHz down to 20Hz. JA states "two pairs of traces overlap below 3kHz; they are the spectra of a dithered tone at 1kHz, first with SACD data, then with external 24-bit data (footnote 1). Both show a drop in the noise floor of around 15dB, suggesting that the Cary player's ultimate resolution is between 18 and 19 bits."
Is 18 - 19 bits ultimate resolution typical of all current SACD players?
Footnote 1: The sample of the original CD 306 I examined truncated external 24-bit data to 16 bits. By contrast, the Professional Version performed in exemplary fashion with external data.
