I've read some of your posts concerning a similar decision I'm facing. I too spent the day auditioning 4 cdp's.

Azur 540
Azur 640
Arcam CD62T

Immediately the NAD was out, to my untrained years it had a muffled sound compared to the other. A&B'ing the 540 and 640 I did notice a smoother sound out of the 640 but it wasn't night and day.

The Arcam was very nice sounding but at a different shop and therefore hard to draw conclusions between the cdps.

I've narrowed it down to 2 and am not sure what to do..... Both players were offered to me at good prices, the question is if its worth the extra few $$$ for the Arcam?

Arcam CD62T ($600cdn taxes included)
Azur 540C ($460 taxes in)

What do you think?
