New Cary DMS 700

I had the Cary DMS-500, and LUMIN T1, at my home, at the same time, and the Cary killed the Lumin hands down. Not even close. I sold the Lumin T1 shortly thereafter.

IMO, if the DMS-700 is only slightly better than the 500, it will be an outstanding value in DACs. 

Ethernet 

Have you ever thought about subscribing to Roon?

EtherRegen is sold out until mid-March. I saw a unit for a good price in US Audiomart if you want to get one sooner.

Since you already have a good Ethernet cable, that’s all you need to get started. Perhaps later on you can buy a good quality linear power supply for EtherRegen
