if you want upsample to 384khz/24 like the hk970 you have to buy the cambridge audio 740C or the Audiolab 8200cdq , the 640C oly does 192/24

Product - Audiolab website

Azur 740C upsampling CD player

I had the same problems with my HD970. "No disc" after some months. They changed the complete drive unit. Again after one year: "no disc". I bought then a Marantz CD player. Now my son (11 years) got the idea that one could replace the internal disc drive, because the cables and plugs are like in a computer. We removed the housing of an old Samsung CD drive and built it in the HD970 instead of the original CD drive. We fixed it with hot glue. No it works absolutely fine (sound, control, CD text, ...).

That sounds a good result

Many players use off the shelf DVD/CD drives so I suppose ( and I'm certainly no expert on this) that the connectors are standard like HDD's and so on.

Well done anyway...

The sound is very similar to our Marantz CD6003 player. Maybe with some more heights.
It works well.

It's a Samsung DVD-Master 12E Model SD-612 Ver.S December 2000. We tried also a Toshiba Samsung CD-ReWritable TS-H292 Nov. 2004, but it was not possible to start a song. Maybe the HD970 doesn't work with rewritable CD drives.
The Samsung DVD-Master is a little noisy when starting the HD970, but during playing a song it is hard to hear some noise.

Some of the popular IDE CD/DVD drives are DSL-710A, DSL-720A. Those are low-speed drives (2X in CLV mode for CD-Audio) - they do not make noises and have lower jitter due to CLV method of reading.
Some of the Samsung drives can be updated with special firmwares to make them "low noise" by lowering the speed.

Arcam, Merdian, Linn, Naim, Apex used the DSL-710, 720 drives in their products.

There are different firmware revisions (I did upgrade mine). And be carefull that the IDE cable, in some players, is reversed from the PC (red stripe to the opposite of power connector). Was not the case in my player...
