The cdp is a year old onkyo sp-405 dvd/cd player. I will try swapping in another one. I dont own a high quality cdp as very recently built my system and I plan on getting a DAC and implementing a music server with a mac mini. I will try another dvd player I have, and maybe even my laptop, just to see.
It has happened on some sigur ros tracks, a flaming lips track, and I believe a m. ward track as well. I will listen to them again and give you exact points. Actually, I am just now listening to The Decemberists, the crane wife, track 10, at 3:30, it appears. It is very subtle though, and my ears have to be on a very specifc plane to be able to hear it, but it is such a high frequency that it is quite annoying. I am beginning to think its my cdp. Maybe I will invest in a high quality universal player eventually. Universal because I have limited space in my rack unit.
As for the rest of my gear:
Speakers are gallo ref. 3.1
Amp is Mcintosh MA6450 Integrated
cables and IC's are transparent cables.
