New Cary DMS 700

Agree w/thyname. You can add all the other goodies down the road. Sablon is another good cable. Supra is pretty nice in the $ 50 dollar range. 

Sure! What’s the link?

I found it. Also, I forgot to mention that I have a Roon Nucleus. Will I still need it?

Hey Gary. Hard to put a number on it but the EtherREGEN is a solid upgrade for the 640 they are asking. But you can then spend another 1,000 on a LPS and a boutique Ethernet cable. Head over here:   Audiophilestyle.com.  Look for the Uptone sponsored forum   All the info you need and more. 
Have the 700 installed. Sounds pretty good out of the box. Will report after a few days. The app is a big upgrade but was hoping I could have all sources in a DMS playlist but looks like just local attached files . Would have been cool to have Tidal,Qobuz,USB and SD in one playlist. 

Benzman, Thanks for the info. I’ll look into it. Give your new 700 at least four days before you start any critical listening. Image focus and depth really locked in around day 4.  I've noticed additional improvements in detail and ambience up through day 12.  I can create playlists using Tidal, USB and NAS. When viewing the playlist page, icons for each source are in the bottom left corner of each album art. This is how I compare SQ of each source to each other. Same song from Tidal, USB and NAS. Makes it really convenient and fast.
