I recently bought a Cambridge 640 CD player based on the impressive reviews alone. I hooked this up to my RA-O1 Rotel amp (+Cambridge Audio Arctic interconnects) with B&W 602 S3's and found it to have impressively clear and clean sound. However I did notice the clinical accuracy and brightness of the top end frequencies to be a little intrusive on my ears, especially on vocal tracks (most notably on the Massive Attack - Blue Lines album). It became very harsh to listen to after about 30 minutes of testing out various cds from my collection and I gave up listening! I swapped over to my £400 Nad T562 DVD player for a comparison and the sound was an instant improvement, with a smoother delivery at the top end. I still want a dedicated CD source because using the NAD DVD is not practical for my set up at home. Is there a way i solve the harshness of sound by upgrading the interconnects? Or is it the Rotel amp that is causing me problems? I'm also considering whether to chuck some more cash at the problem and just upgrade to an Arcam CD73T that may be a little more refined. what do you think is the best solution? cheers!
