Anyone heard the E.A.R. "Acute"?

I have the EAR Acute 3 CD player and wondering about tube rolling myself. Has anyone tried the Genalex Gold Lion E88CC/6922's in the EAR Acute? I saw in the thread that one user loves the Siemen's 1960's but what about that tube did you like? What makes it a good match for the Acute?

I would also like to learn more about the tubes that have been tried in these CD players. Thanks.

@djfst. I like it because the soundstage was wider and deeper than the other tubes. It was more 3d as well. It was more enveloping. Most tubes I tried had an area where they were weak at this tube seem to do most everything at the good to great level. Instruments sounded a little more real.

I was also interested in the Mullard CV2493/6922 I saw on Upscale Audio. Anyone ever use these or the Gold Lion 6922's in the EAR Acute?

Calvinj, I looked on Upscale Audio's site for those Siemen's tubes you are using with the Acute, but they have about 4 different ones in the 6922 / 6DJ8 / 7308. Which specific ones are you using and how much did they cost? Plan on giving Kevin Deal a call and talking things over, maybe ordering a pair of the ones you found success with. Thanks!
