Once again I apologize for my doubts regarding the MCD500's capability to accept anything except 44,1 kHz via its digital inputs.
However, I consider the statements below from
http://www.mcintoshlabs.com/products/1219.asp are missleading.
General Specifications:
Digital Input:
Optical: - 15dbm to -21dbm (PCM1 - CD Format only)
Coaxial: 0.5V p-p/75 ohm (PCM1 - CD Format only)
Sampling Frequencies: 44.1kHz (PCM1)
Thanks to my friendly Mac dealer an MCD500 is now decoding one of my live 48kHz DAT recordings in my home.
It sounds very smooth.
I have spent most of the weekend to thoroughly test just about every facility and mode of operation except the optical inputs and outputs, but including use of my old CD-drive as input to it, and the digital output to feed my old DAC.
Using the variable output feeding my power amps directly was very slightly superior to the fixed output via my C2300.
Thanks to the trim function of the C2300 it was easy to calibrate the inputs from the MCD500 and my DAC.
A few very experienced listeners have visited me and we played a wide variety of music, the major part being acoustic classical and contemporary.
On exceptional recordings the definition of the rear corners of the recording venue is clearly superior. It is soooo smooth, rough recordings are easier on the ears, BUT it smoothes over the microdynamics compared to my old DAC.
The finest nuances ov vocal or instrumental articulation aren't there.
Considering that my current drive and DAC are 20 (yes twenty) years old (and in daily use) that is a major disappointment!
Even if the MCD500 is built like an armored car and mine is built like a tank and would probably have cost more to build today than an MCD1000 and MDA1000 together, I had expected the MCD500 to be superior in every way.
