High resolultion cd player


I'm talking about redbook here for around $1000 used, I have a very musical goldmund SRI2 integrated, so all I care about is resolution and soundstaging and imaging, not worried if its a little cold because this will just help balance out my system in conjunction with the Goldmund. What is out there that provides among the best resolution? what do you think of the Resolution Audio CD50 vs the Theta Miles, the Classe cdp-1 or the Krell kav300i. I have a Cal Audio CL-25 right now and comparision would also be great. Any input would be appreciated and if I'm missing anything let me know!

Not sure if you are interested in DAC's, but the Birdland Odeon-AG (with variable out) is very good and can easily compete with those costing many times more.
I Presently use, and would Highly Recommend, the ELECTROCOMPANIET EMC-I !
Its very Well built ( like a tank ) and Sounds as Good as Anything out there. Listen to 1 if you can - you Won't be disappointed. Good luck !
