Hi Tony,
The new p02/d02 has a slightly different sound signature than p01vuk/d01 I compared with. I cant comment on full vuk upgrade since the d01 I compared with was a well broken in d01 store demo piece from Spearit Sound without the vuk upgrade. The d02 and p01 vuk I used had more than 1000hrs. during the comparison, but the p02 which was exhibit demo piece was not completely broken in.
Cables were Esoteric 6300s for AES and audio out. Power cables were 7300s. The clock was G0rb. Filter was s_dly1 on D02, FIR on D01.
In short the new combo was slightly more detailed ,extracting more spatial information then the older one. The older one was more together and had a sound slight more cohesive and laid back. The newer one was more forward and it was highlighting some details more than other. The new combo had a larger and bigger sound stage. The older combo had a deeper sound stage than the newer one. P01 vuk /D01 had slightly warmer and thicker mid bass that helped some leaner recordings. On the other hand the new combo was more refined and didnt sound coarse with greater separation. On some cds the older one was better(especially lesser recordings) on some other the new one.
With SACDs the winner was the new combo which is due to the fact that the older d01 down converts dsd signal either to 88k or 176k pcm.
In short one is more laid back and cohesive,also slightly less refined the other one is more dynamic, clean but also more forward and very slightly less cohesive. They may sound closer with better cable choices that can compliment slight shortcomings or personal choices.
They are both great sounding digital gear but I would go for the newer combo for true dsd support, usb capability, the new 35 bit processing, plus easier upgrade path to new p1 or d1. The d01 has a great built in analog preamp. But since you have a preamp. that is not a plus.
