Audio Research Ref: CD8

This weekend I am hoping to listen a reasonably burned CD8 vs CD7 in my system. I will post the results.

My X-mas tree is already in the bag. Please let us know your findings. I would think unless the CD8 is clearly superior, that the CD7 would now be great value for some.

It is on sell here on AudioGon already two modified CD7. I wonder what can be the rationality behind it. Any ideas

Probably people who are upgrading to the CD8.
Anyone else besides me have input on the CD7 power supply modification ?

I also think Dweller are right. It seems that ARC have a development strategy with module solutions. My guess is that we soon can see a Ref PH8 (PH7 with the "new" power supply and?) CD5's DAC is technical better but many still prefer CD7. My guess is that CD8 is the best of both.
Next major upgrade of Ref3 show the future. ARC's strategy is little tireing. DCS for example have another customer care philosophy with free software upgrades for longer lifecycles.
