Amp for JBL 4365

Considering to upgrade the Amp to better drive JBL 4365.
Am using Octave V80 with Super Black Box and thus have shortlist a target list as:

Octave HP300SE + MRE 290 with Super Black Box
EAR Yoshino 868 + 890
Audio Research LS27 + Reference 75

What do you think can be best match with JBL 4365 and would like to have your recommendation.

Thank you all!

I am using the Gryphon Diablo at the moment with my 4365.

I am contemplating to try the VAC 160i integrated or the mastersound 845 evolution

Since your last post, what have you tried and have you settled on anything yet?
