I have just recived an email telling me the insides of the copland are like a wadia 850 with two Burr-Brown PCM1702 per channel plus a custom-built reference master clock to which the mechanism is slaved. This clock is located on the digital-to-analogue circuit board, its job to optimise accuracy and allow a cleaner conveyance of audio information.Digital filtering is performed by Pacific Microsonics' eight-times oversampling PMD 100,
the last bit not sure about as the PMD will allow HDCD to play and I did not think mine plays them so getting one out now
Dave,
I've only just seen this post but the information above is correct. Also, the Copland sounds better when used via its balanced output but in your case, given the amps you use, you won't be able to experiment with balanced vs single-ended.
Tony's comment about the Copland CDA-823 using a Teac VRDS mechanism is not correct. The CDA-823 uses a ROM drive and is the first Copland CDP to utilise such a transport mechanism. IIRC, the Teac VRDS transport mechanism was last used in the CDA-288 almost 10 years ago. When the CDA-289 was introduced, Copland switched to a Sony transport mechanism which was partly customised by Copland before being inserted into the CDA-289.
Still with Tony
, the Copland CDA-823 has not yet been modded by any reviewer (journo) as far as I know. The CDA-289 was indeed modded by Trichord for a reviewer called
Dave Davies. The CDA-289's clock was not changed by Trichord as they concluded that the Trichord clock 4 (or so) could not improve upon the standard clock in the CDA-289. The same applies to the CDA-823 (Dave's CDP) where the clock is custom-built to an even higher standard than that in the CDA-289. However, I'm not sure what the connection is between
Dave Davies and
CJ though.
Enjoy the musicâ„¢
