Audio Research Ref: CD8

I suggest everybody to do the mod. All cd7 will show the problem if one of the two 6h30 drift from each other. The use of only one tube avoid that. On the sonic side can´t say nothing, I did not bring mine for the last upgrade yet.

Correct me if I'm wrong, but I understand the CD7 does not upsample (like 8X, etc) and uses the Crystal 24bit sigma-delta DAC.

Does the new CD8 upsample? and is the Burr Brown 24 bit DAC a ladder type or a sigma-delta? Does anyone know what Burr Brown DAC is used (PCM1704, etc)?

ARC does not believe in upsampling.

To say that I had to pry their jaws off of the carpet is an understatement.

How many times have I heard "jaw dropping" hype like this before? ARC churns out upgrades as fast as anybody.

AFAIK CD-8 uses the same DAC chip as CD-5.
