Pioneer multi-disc CD recorders for mod?


Hello all,

I am talking to Stan Warren, about modifying a CD player and/or recorder for me. He likes the Pioneer units with Burr-Brown DACs as a starting point, and I am thinking about which one to get. Stan completely replaces the input and output stages with his own circuitry.

With that in mind, does anyone understand the differences between the PDR-W839 and the PDR-W739? Both of these CD recorders are still sold, though the latter is more expensive ($750 list vs. $600) and it seems a bit older.

The Pioneer website is no help here. Can anyone explain the differences?

Thank you!

Hi Kenny,

I didn't see that model of recorder listed on the Pioneer site; is it definitely a current unit?. The units we've mentioned have 3-CD players built-in, for what it's worth.

The basic idea behind these mods, as I understand it, is that Stan believes the lower-end Pioneer actually has a better-sounding DAC than the higher-end gear, if you make sure to get a model with a Burr-Brown 17xx (I forget the model number) DAC. These DACs are cheap (under $5.00 in quantity) but excellent, better, according to Stan, than the inhouse DACS Pioneer (and other vendors for that matter, put in their higher-end gear.

The more expensive gear may sound better "out of the box", because the other circuitry (other than the DAC) may be of better. Stan basically replaces all the analog circuitry, though, so he believes that ironically the lower-end unit after modification sounds better than a higher-end unit, because of the higher potential of the DAC. So he points people to these units for his mods (not necessarily as the best choice unmodified).

I hope that's clear. I hope to post soon with results of my "mod" research.
