Maybe I missed it but what is new and improved? Been eyeing the Dialogue HP integrated which is now the Evo 400 integrated for quite some time.
Looks to me like the new Evo has balanced inputs.  Is that the only difference for 600 bucks?
so all the other "nice-ties" like remote control switching between triode and UL and the bad tube indicator were part of past models too?  Obviously those type of things don't effect sound and seem more geared towards making tube gear seem less "scary" to use by a larger target market.  Hopefully the new model includes features that drive sonics as well.
