New Cary DMS 700

 I have the 600 and it is a great piece. 

The 700 looks to be on the next level. Ladder dac
Hello out there in audiophile land. I just ordered a DMS-700 arriving this week. Pairing it with an ARC LS-28 and a REF 75 SE.  A couple of questions regarding tweaking the sound.  Does a different power cable make an audible difference? I also read some of the post regarding the EtherRegen what does the device actual do? Clean up the ethernet signal? Is there that much noise in a ethernet cable?Has anyone compared the Cary DMS-700 to the ARC DAC 9 with and Aurender streamer?Feedback appreciated.
i just bought the IFI Zen Streamer it $399 and sounds utterly transparent. looking for a new DAC to pair it with. i must say my venerable NAD D1050 is providing more than adequate for now running Roon.  Rega speakers and electronics.
