I’ve been using the Mk2 forever, and found that with my Rose RS130 streamer I had to invert the channels with DSD. I was just playing a DSF I’ve played many times before (the famous Reiner Scheherazade), and started thinking to myself “something ain’t right!” Lo and behold I suddenly had to switch the DSD channels back to Normal on my I2S input! 
No change to anything. Certainly no change to DS FW. No change to RS130 FW or SW. No change to JPlay. Nothing! I can’t figure it. I even used the PS Audio set up disk (DSF on my NAS) to check and sure enough the Left channel is Left when now the I2S DSD channel are set to Normal. Makes no sense. I wish Ted were here.
…uhh…where’s Ted?
Ted seems no longer a part of PS Audio or this forum.
Yep, I know. I can contact him directly, I guess, but I wasn’t sure if anyone else had this happen.
He’s not. I do not believe he still reads these forums and certainly hasn’t participated in a long time. I think he’s off doing his own thing.
I miss Ted.
Me too. I’m thoroughly enjoying his work right now.
Brian, the thing is I had everything set up properly for the RS130 when I got it. Checked everything multiple times. Now for some weird reason I no longer have to swap.
That’s weird. No firmware changes right?
Nope
I recall clicking on his avatar a few months back and seeing he had in fact read a thread in the previous months (don’t recall specific dates). I just searched on his name going back to January 2024 and got no results! That predates the PMG DAC introduction by over a year so he must have recently deleted his posts. Odd that his name came up in the “search member” box.
