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??
If you like the CV2492 you would go wild when you hear a Mullard CV2493 they are the unbelivably clean and full. I have to look up where I got mine. They were advertised for a long time about 6 months ago by an Audiogon dealer.
