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?

Maybe I'm not sure what I should be listening for? When I got the Ayre pre I could hear a difference right away. When I got the SMC power amp it was much harder to tell. When I got the Cardas cables I knew I couldn't give them back.
