That looks like a very very nice amp, Doc77 ; do you have Treasure tubes on it ? they say that Shuguang Treasure are the best KT88 tubes, you also can try Tung-Sol KT120 if you want more power and better dynamics, but you have to make sure that your amp can handle the KT120 properly, since the KT120 tube draws between 100mA (.1A) and 300mA (.3A) more filament current than a standard KT88.
Regarding the Utopia Be, I'm not that convinced anymore, since thou it has his share of qualities, the sounds is a bit on the artificial side.. it doesn't sound as natural as it should and it can be sometimes bright and fatiguing...
Now regarding your speakers, tell me please if you have the standard version of the Cirrus or upgraded. The Cirrus is on my short list, along with the Evolution Acoustics MMMicroOne and I am waiting for reviews on the Micro1, to see how does it sound on some relatively unexpensive gear, since when it was presented at audio shows it was driven by 40k worth of equipment and I don't have that. Did Evolution Acoustics MMMicroOne seemed sweet and natural sounding to your ears ? Did it have the same character as the Cirrus ?
PS: I hope I made myself understood properly, if not, don't hold it against me, english is not my native language :)
