FYI-I received an email reply from Pro-Ject 😀 They asked for the serial number of my CD Box, indicating there were "historical problems" with certain units before "the updates." We shall see.....
At the moment, I am really enjoying the ARC CD6SE that is on loan. While not quite as resolving and tuneful as the Pro-Ject CD Box, it is tuneful, has a wonderful tone, and has synergy with my other ARC components. In all, when working, the CD Box is a wonderful transport because it achieves a balance of resolution and musicality.
Additionally, the DAC in the CD6SE player is also top notch. I'm running an Aurender music streamer/server through it, via USB, and it sounds terrific.
