I've had my DAVE for a few weeks now and have a couple of new owner questions. Apologies if these have been covered -- with 800 pages I'm sure these have variously come up before, but I didn't have any luck in searching the thread.
1. PCM Plus setting vs. DCM setting. What's the deal? 95% of my listening is through Spotify, with a splash of lossless through JRiver. A/Bing both modes sounds the same. Is there an accepted "optimal"? I've been on PCM for a while now and love it, but don't know / can't hear the difference.
2. I leave mine on 24/7. I use display mode 4 so the screen turns off. Display mode 3 is prettier. Is there a potential burn in issue if I use a mode without the screensaver?
3. Given I'm using stock cables, Spotify HQ, and relatively older LCD-2 v2.2s, where would you go first on the upgrade path? I'd like to get a set of LCD-4z cans, so that's in the works, but what can I do on the software or additional hardware side of things to continue to see improvements? I put the stock cable directly into the wall, and then into an old surge protector and didn't notice an audible difference, so I'm assuming the power supply in the DAVE is good enough that improvements in the power cable aren't gonna do me much good, but I'm open to alternative arguments. I'm probably most interested in what software / source tweaks have been working; e.g., should I try Tidal? Should I try buying more of my music so I can run it through JRiver and get a bit perfect output (and where do you usually shop)?
