LInn Genki and Sonos - Adding a DAC


I have both components above and I am considering adding a DAC to my system if it will enhance the performance.

I am not interested in changing the Linn or Sonos components, just making an improvement in the sound at a reasonable price ($750 or less).

I would like to spend less than $750 used or new for the DAC. It needs to have 2 inputs so I can hook both components to it.

I would appreciate recommendations for audition. The Linn requires a 75 ohm coax connecton. The Sonos can use that or an optical connection.

Thanks for any purchase or audition recommendations. If you think it will not matter or have a significant improvement, I would also appreciate your thoughts.

Thank you Gavide256 and Audioengr for your comments. I was looking at a Cambridge Azur Magicdac at a local shop because of the dual inputs as well as toslink, coax and usb inputs. Any thoughts on this?

Davide256, would I need to solder to make the cable or just crimp?

Audioengr, what is a Synchro-Mesh reclocker?
Jperry - Synchro-Mesh installs between the source and DAC. It is digital in and digital out. Reclocks and reduces jitter. The input and cable does not matter. the output cable should be a good one. It can be further improved by upgrading the wall-wart to a Hynes linear supply.

Audioengr, Thanks for the info on the Synchro-Mesh. I will look it up on-line.
