Shardone, I actually bought one of these a few back due to some glowing reviews on here by many, including yourself. I have a question for you though; looking at your gear, pretty much anything would sound it's best running through that rig. Have you tried any of the newer DAC's to compare them to what you currently have?
1) Wyred DAC2
2) Bryton BDA-1
3) Eastern Electic Mini DAC
4) Berkeley Alpha
5) PS Audio Perfect Wave
I would be shocked it you didn't like any one of those better.
I hated mine, tried many afterward, maybe it just didn't match well with my gear, I had the problem with the AWESOME (all caps Linds-fart) McIntosh 501's. Great amp, sounded like crap with my gear. Went to a buddies system and lit up his B & W's like nothing ever has.
Fact is though, on A'gon it seems that most comments about the Benchmark DAC's have been negative.
