audio valve eklipse or aesthetix calypso

thanks all, I might go with the eklipse since it's about 4000$ here in thailand while the calypso is about 5000$. anyway I'll go for the audition this weekend. Teejay, do you think the eklipse will blow the vtl2.5 away by a large margin? the vtl is quite good in my system which makes me think what can the eklipse do more? I'm just curious

regarding tubes replacement with NOS tubes, do we have to change all four of them or just the front or back set? also I notice the faceplate of the demo unit at the dealer is different from the picture I see in many forums, including audio valve website, the characters of the words "eklipse" is different, and also the characters on the input is different, other than that looks pretty much the same. I asked if the unit was made in germany and he said yes. is it the newest version?

thanks, I just auditioned yesterday and placed order already, the unit will come in the end of this month, now the problem is what colour should I get black or chrome :)

thanks again Teajay,I'll try tube rolling after getting the unit. I notice a little roll off on the high frequencies or may be it's the warm characteristic of the eklipse.may be the dealer set up.

Update! just got the eklipse yesterday and the dealer also offered a demo unit which is very new of the Coda CSX amp so I took it home too. The eklipse is being ran in and it sounds fabulous already. Thanks all for the comments. Anyway,any opinion on this Coda amp is welcomed.
Cheers
