Which 300b amplifier for Devore O/96


I am looking to upgrade (and simultaneously downsize) from Coincident Frankenstein Mk2 300b SET monoblock amps to one of these stereo amplifiers.

These are the four candidates so far: Nagra 300p, Luxman MQ-300, Wavac EC-300B, Air Tight ATM-300R, Shindo Cortese 300b

My preamp/dac is Bricasti M12 and my speakers are Devore O/96.

I am not looking nor interested in any other 300b amps at this point.

If anyone has compared one or more of these amps (esp on an Orangutan) do chime in.

Where I live I can probably demo the Nagra and the Air Tight but nothing else.

Thoughts?

ESSRAND,

Perhaps these previous posts supplied all the information you wanted.
If not, one other source you might want to engage in a mind-meld with Glen at Tubeaudio.com He sells Devore, Line Magnetic, Nagra, Shindo, Leben, Innous, Odin and many others. Ten minutes with Glen or Bill and
you can sh-t can most the above.
@essrand Just commenting so I can come along for the ride. Very curious how replacing the Franks goes, please report back over the months as you try various options.  

Can't remember if you commented on one of my amp threads, but damn I struggled to replace mine in driving my Coincident PREs.  Tried some quality class D, class A, and OTL amps but always preferred the Franks.  All those amps bettered my monoblocks in various ways, but it was never quite enough.  I am currently building a First Watt F4 to use as a "booster amp."  Everything I read suggests that putting it on my bass cabinets (driven directly by the outputs of the Franks) will greatly improve my low frequency control.  I'll also try running speakers full range from the F4, but fed from the Franks loaded by 8 or 16 ohm resistors.  6moons claims this gives you all the liquidity and dimensionality of a non-distorting set (because it simply sees a perfect, constant 8/16 ohms), but with the full current and bass control of a great class A SS amp. 
@firstnot  Damn, what a perfect situation...
I dont know Glen or Bill, but 10 minutes with either of these guys might result in a goldmine of information or it may result in ten minutes of competitive product bashing and only an attempt to sell you their products. I hope it is the former, but please be careful. 

I do know that in my conversations with John at DeVore he often shows with push pull designs which may or may not be entirely the result of sonics. With our group it seemed that we didnt know how much better the system could sound until we added more power and what I believe to be an inherently superior amplifier design (provided the speakers present a higher and stable impedance load). 

Seek advice first from those that have no dog in the fight.
