Come on~!
what you talk about versatility ?!

Arent we all here for the best sounding equipments we can afford and enjoy ?
If versatility is what u after, buy a Cosmic then, no other amp are as versatile than Cosmic ,which also sounds very good from what I read. You also have the choice on Jan's porta corda that he is now selling. These 2 amps will give u all the versatility u seek~!
If you are doing the listening at *home*, how is the Creek or MORE versatile than xcanv2 ?

Both need to be plug in~!
I think you need to set ur priority straight before u buy the actual amp.
