Tube Rolling on DK Design MKII


I just picked up one of these integrated's about a week ago. I am looking for suggestions on tubes. What is the best sounding tubes for all types of music - mostly jazz, classical, and soft rock.

Where do you get the Cryoed Mullard CV2492 tubes? Also, have you heard of Amperex Circa 1962 6dj8's and where can I get them - these were reccommended highly
Can I assume, that the Cryoed Mullard CV2492 is a drop in replacement for the 6922??
