Gryphon Diablo 300: at the top of Integrated Amps?

Gryphon has been making integrateds for decades, he knows what he does. Try to find it used, no-one sells them and they sold a lot in Europe and Asia. Ypsilon appears to have more purist approach, they didn't make integrated until very recently. They also make $35k phono stage which is said to be extraodinary. 
raindog031, you are certainly right about the match. I think, Flemming of Gryphon wanted to create a very versatile integrated that would match very well with a wide variety of speakers. And it should last for a very long time.

In addition, at this level there will be ’cultural’ differences. Gryphon represents the essence of Scandinavian sound - clear, dynamic, deep, on a darker side of neutral, and Ypsilon will weave the sophisticated tapestry of the world music. Gryphon will dominate whatever system you put in in and whatever you play, while Ypsilon’s presence will be more subtle and soaring.
In a perfect world I would choose Ypsilon, then I would ask Michael Green to build me custom speakers to work perfectly with it and I would send the Ypsilon to him for that. Then I would consult with Dimitros about recommending external non-Ypsilon phono stage. The alternative to Michael Green custom speakers would be Lansche. Purist Audio, Echole or Stage III cabling and that would be a great sound.
In not so perfect world I would almost certainly choose the Diablo with phono, either 120 or 300.
In less than not so perfect world I would first try Pass INT-60 for $6k used and see what happens.
All these would be for medium size room, and I don’t listen to opera, choral pieces and big orchestra music. If I did this would be either Diablo 300 or separates.
Swiss route is interesting too, though I am reasonably certain that I would prefer either Scandinavian or Greek/Middle Eastern sound, that’s either Gryphon or Ypsilon.

I like my Ayre AX-5 Twenty a lot.  You should put it on your list to check out. 

We may like our whatever we've got but this discussion is not about that.
