I agree with Coffeey. I own the CD36 as well and am very pleased with it. Although I have not done any great compare/showdowns with CD players... I too have found changing your pre-amp and/or amp will give you a better bang for your buck as far as sound improvement or just change for the sake of change.
Arcam cd36 vs perraux dac
I have had an arcam cd36 cd player for a couple of years. Recently I was convinced that if I buy a perraux silouette dac and use my arcam as a transport only I would notice a substantial improvement. This advice was predicated on the assumption that burr brown dacs are superior to wolfson dacs. So far I haven't noticed much of a difference. Could it be that the perraux is not yet burned in or should I not expect much of an improvement at any point?
