Help choosing integrated


I'm currently shopping for an integrated amp for my main system. Got a few integrated amps on my mind. Since I haven't had a chance to audition all of them so I would like to learn from your experience and get your input before making the final decision. Here is my short list (all used):

Gryphon Diablo
Vitus RI-100
GamuT Di150
MBL 7008a

The rest of my system includes:
MacBook Pro/Audirvana
Anticables 3.1 USB cable
Hegel HD 25 DAC
Focal Diva Utopia Be
Synergistic Research Tungsten Interconnects
Triode Wire Lab Speaker Cables 

Thanks in advance for your feedback!

@arsh Thanks for sharing the details. I auditioned Sasha's a few times and I was impressed. 

@georgehifi Thanks for the insight! I auditioned the Diablo (older version, not the the new Diablo 300) in person and I liked it very much. That's why it's on my original shortlist :)

@akg_ca Thanks for the advice! What's your impression with the OSIRIS? Source and speakers? 
The Modwright KWI-200 is also worth putting on your list. The Modwright IA has plenty of power to drive your Focal's (very fine speakers) to audio bliss. This IA has a tilt to the warm side and in the used market is well below the price points of the high quality IA already under consideration. Happy hunting.
