I would suggest you listen once to the first violin concerto. It has got two movements and they actually have an "idea" behind it: The first one is his declaration of love for Stefi Geyer (who did not care a fig) and the second one is a tantrum about said fig. It can make perfect sense, and...
David Bernings original ZH270 was Franco Serblins favourite test amp for his early designs, including my then Guarneris. And the Combination of Beauty and Speed still works wonders in their current iterations.
Only Caveat, I have never heard the more expensive Kondos; nevertheless, my...
I had two suggestions, that have been partly mentioned elsewhere:
Why don‘t you try something like Pap Trio Voxativ (which I have and love) or Pap Trio Horn, don‘t hesitate because they seem cheap..
Or: Get Yourself the Berning Quadrature Z‘ (Disclosure: I own nearly all of Berning...
Seems a perfect match for David Bernings Quadrature Z ( disclaimer: I am selling some of my Berning gear, as I simply have other Berning amps that fit my low power needs. And Audio Consulting for even lower power needs..this is where my open baffle pap voxativ brought me!.)
If passive, then go with Audio Consulting straight away. The venerable silver rock TVA is not only in my opinion the reference against which Active stages have to be heard (Of course if impedance matching solved)
Could anone elaborate on the kii three (or the Grimm LS1), as they are by the same hand as the MM. I have to evaluate them after having heard them once, gathering information now. Not hijacking the thread, but expanding it in the logical direction, if you don't mind?
..It was my mistake as well to think the Berning 845/211 were SET, they are Triode/ZOTL amps.
I am not actually writing to correct anybody, but I must add, that I can't hear switching amps in my Quadrature Z's..(yes, I know, they are not SET, nor OTL ;-)
