ARC CD 3 mk II upgrade with DAC 8

Supermodified - Congrats on the DAC8. I think you got a fantastic deal on it.

I acquired a DAC8 to use with my existing transport and also to allow for Computer Audio / Hi Rez files. In the end I made the decision to go for the approach that didn't make changes to the actual files/cd's we purchase and plays them in their native format.

A key part for me is explained in the DAC8 manual re: Audio Device Software Drivers:

"The DAC8’s USB driver software provides your computer with special high speed audio drivers not supplied by MS Windows or Mac OS. The ARC USB drivers are specially designed to assure low jitter BIT PERFECT data transfer between the server/computer and the DAC8 at all sample rates. Our drivers setup the USB interface to guarantee bandwidth, independent of active bulk transfers from the hard drive."

Also a very good read document IMO on the engineering behind the

DAC8

From a pure DAC performance perspective from ARC.

The ARC DAC8 is identical to the current ARC REF DAC except for a tube output stage.

Hello Chris,

The DAC8 uses the same digital chips that are used in the Reference DAC. The REF DAC has a vacuum tube audio output instead of a solid state design.

Please see attached file for more information.

Am very happy I brought this DAC in. Hope you enjoy it as much as I have. Happy listening.

Currently I am building as small dedicated listening room (9' ceilings, 14' x 16') hence the reason I felt that the REF 75 should be more than sufficient. As I have a couple of weeks before completed, the REF 75 is unopened new in the box. can't wait to get my gear reconnected. Previously I was using a Pass x250.5 but have longed to get back to a full tube front end. I have decided to make the move to the DAC 8. thanks again for feedback.

When you get serious send me a message and I will build you a DAC for under $2K that will blow your mind.

Happy Listening
