The Yamaha cdr 1000. Also, the HHB's are good sounding units. I haven't heard the 630 from HHB, but this unit is reasonably priced at $650. For A-D recording you should look at the Yamaha it has Apogee's UV-22 filtering. I have a Marantz cdr630, no longer available. I use it as a digital record unit only and it works well. When going from A to D I use the SBM processing in my Sony PCM 2600. I have listen to it as a stand alone player and transport. As a player it is okay. A little harsh and somewhat flat, "in terms of sound stage". As a transport it is okay, too. However, in either case it does not match the sound of my Rega Planet. Which you can find used on the net at a reasonable cost. I quess this is a long about way of saying; if you are going to record D-D look at the HHB 630. It may sound good, their other units do! If you are going to do A-D,and want a good sounding player go for the yamaha cdr 1000. It is pricey but worth it. You other option is to buy a cheaper CDR, always buy "pro", and get a seperate cd player for play back. Again, at the going used price for a Planet you can't go wrong and you would be able to keep it under $1000.
