You folks keep speculating... at this point I'm just confused.
I got about half way through the song list with the Ciunas and DM Source, and will finish that tomorrow. Then I will do a bit of comparison between the Ciunas and the Metrum to confirm what I think I heard. No need to go through the whole list again.
I also need to go back and redo a bit of the Benchmark testing, because it turns out I might not have had DSD/192K engaged when I demo'ed it earlier. Too many DACs, too many drivers to set up. I checked one Shelby Lynne song tonight and heard no difference with the DM source, but want to do a more thorough check tomorrow. Again, I don't intend to go through the entire list unless I hear some difference in the first couple of songs.
Then I'll do either the Chordette or the Yulong, or both, and you folks can pay off your bets with each other.
Regarding the Benchmark, make sure that the USB 2.0 functions are engaged on the DAC or you won't be using the USB 2.0 driver...I made that mistake a couple of times...thought the DAC was set up correctly and it wasn't. Besides not being able to play anything above 24/96 or DSD, I noticed a definite improvement in sound using the newer driver. In my case, listening to mostly Redbook, it was easy to overlook. I think, though, I'm going to look at an Eximus or HEX myself as I'm finding the Benchmark to be a bit fatiguing combined with my Focal CMS50 monitors and my HD800s.
BTW, great thread and tremendous effort Gary...I get burned out just comparing a few pieces of equipment, what you're doing is phenomenal!
