To Cryo tubes or not to Cryo tubes

During a nite of tube rolling with my First Sound pre, a fellow audiogoner and some good wine, we tried a pair of Telefunken 6dj8, National 6dj8, and last a pair of cryoed paAno(rockets)6h23n-eb What a big difference in soundstage with the cryo tubes much more open and dynamic in contrast to the nos tubes. realy begged for more vinyl.
Now for the downside, the cryoed tubes were much easer to listen to vinyl then to listen to cd's. The nos tubes were smoother, softer with cd's, the cryo tubes with cd's were a bit fatiging(upper frequency graineyness or distortion).
Have any of you tried cryo tubes? what are your experences and thoughts,

I'm using cryoed EH6922 purchased from ATSI in Florida. These tubes are among the very best in my Audible Illusions L1 linestage.
These tubes are barely indistinguishable from NIB/NOS Amperex PQ white label (USA). Compared to non-cryo Russian/Czech tubes, they have a tighter, less woolly bass, more neutral midrange, and a cleaner slightly more extended treble.
