Am I deaf?


Hello all,
Just got a Chord Qutest to use as an outboard dac with my Oppo BD 105. Connected the Chord to the Oppo coax out with an Audioquest Carbon coax cable. $2100 for the Qutest including the cable! I'm not hearing it. I think the Oppo dac may sound a bit better than the Chord. Tried all the filters. Am I nuts?

Thought- These Harbeth C7 speakers and wonderful but not that revealing. I notice you can't hear the reverb in rooms like I'm used to. Could it be difference is just not being resolved by the Harbeths?
Can you get a second and third set of ears in for their take on differences or non-differences, etc.?
Have they had a chance to listen to your system, before and after the changes?
