Glad you worked it out. The J2 is one of my favorite DAC's under a thousand dollars, together with the VMV D1SE and the Topping D70s - both of which cost over twice of what the J2 costs.
What would be the point of sending an analogue signal to a digital to analogue converter? It doesn't need converting.
I like the Tempotec Serenade X as a music streamer DAP , I also have a Hiby R6 2020 with usb/Coax dig out so not end of world . All would be solved if the player had a digital outputs.
I'm confused. I've looked at the product website for the Tempotec Serenade and see no evidence of streaming capability. It's only a DAP and DAC.
Your right I was excited about winning it on a contest and using it as a media streamer... It does stream as a BT out only not WiFi or network a bit misleading unless I haven't figured it out yet the owners manual is non existent LOL.
That sounds more likely to be a bug in the Pi4 software stack. Are there RopieeeXL forums you can ask on?
Sure but since I've used this exact Pi4 setup to play DSD files on at least 3 different DACs, this seems more like an issue with USB on the J2. Has anyone here with a J2 successfully played DSD files with correct left/right channel alignment?
I very much doubt this is in the signal from the DAC. Well designed, well measuring dacs don't sound different if they are working correctly - and even when not well measuring, don't sound different in this way. There is nothing a DAC can do to the sound stage for example.
That wicked hum is a ground loop. It is not a problem with the product (DAC) but is a symptom of the way your system is set up. (Ground loops are system problems, not component problems)
