Saki70, I have heard CDPS from both Electrocompaniet and Wadia, not from Resolution Audio, and would share the following regarding their sonic signatures: The Electrocompaniet is very "lush" sounding with very good clarity and extension, but more towards the warm and tube-like perspective. The Wadia is very detailed, dynamic, and is still smooth sounding but not as warm sounding as the Elctrocompaniet. Besides your personnal taste, I think it would come down to system matching/synergy in deciding which would be the best for your ear's.
