Dave do you have the facility to run the cd player in balanced mode with your current amps. From what i've read (alas haven't heard) the Copland is a bit of a bargain

The copland has balanced outputs but the valve amp has not got balanced inputs

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:cool:

The Copland runs 1702's in dual diff mode.

Its a nice player has a vrds tranny too. I believe that Jorno the odd one lol has modded one of these. never remeber his name one of CJ fave guys

The 1702's are musical and full sounding nice chips IMO.

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„¢

Sorry Dave wrong player, its an older model, not Dave davies either Lawrie for that player, I just can't remeber his name, hes' famous though for that stupid scoring/marking system he uses.

I don't read the mags, but I'm sure you'll fill us in.

The whole point of the clock change isn't the clock IMO, but what surrounds it.

Tony,

Like you I don't buy the audio comics but I'm willing to bet you GBP 1000 that it was Dave Davies. I don't know who else you could be referring to though but he was the only reviewer-owner of a Copland CDA-289 that had it modified. Anyway, before you lose GBP 1000, I suggest you check your information properly.

Remember that I still do own a Copland CDA-289 which is not being used at the moment and I also have my sources of information which are not the audio comics.

Enjoy the musicâ„¢

Lawrie,

I don't know his name, however he does have one and it has an N/c (I believe he did a review of it?) and other stuff on it. I thought it was the guy who does the silly points scoring thing? I'll check tomorrow

Added, Seems I'm getting senile in my advancing years

DD has the copland, the chap I was confusing him with was M.Collumns, he had another player, so sorry for any confusion
