I really like, with almost any reasonably efficient speakers, and some not so efficient, the Synthesis A-40 integrated amp (digital dac included). It utilizes KtT-66 tubes in pushpull to deliver 40 wpc.  If you demand more power their A-100 amp delivers 1000 wpc by doubling the number of output tubes.

I would also hazard a guess that an Audio Note Oto would work well.

 I am in the camp of keeping what you currently have. Virtually everything in audio is a trade off to some degree no matter how small. You get another amplifier that gives you more of  “this” but then loses some of “that”. The Audio Note OTO I believe would be a terrific match with your speakers. It is an el84 with its inevitable strengths and weaknesses like any other amplifier.

it could be as good but I don’t see it as better than your current Shindo or Elrog/Aric Audio 300b. . Higher power push pull tube amplifiers would take you in another direction as far as I am concerned. I don’t know that this would necessarily be any improvement with the Nenuphars. It could certainly work out well for you, more likely different rather than better. Just to let you know I am bias positively  toward high-quality low power tube amplifiers. Just me. I believe that you are in a very good place right now.

"I am in the camp of keeping what you currently have."

 

Charles, agreed. I don't have a burning itch (is that a mixed metaphor?) that needs to be satisfied with new/different equipment. In that sense I have slowed down over the years. My question was more from curiosity. If someone wrote that brand XX or a vintage YY manages to get a bit more of 'everything' then I would keep my ears open at AXPONA or Audiogon.

 

Of course the price for converging perfection tends to increase exponentially. For example, I have followed Vinnie Rossi since his Tri-Path days, but his new line is a bridge too far for me. The new Brama preamp goes for $35,000 and weighs near 100 pounds!

 

That said, I know I am very fortunate to be able to have, not one, but two great sounding systems. And I have always been a bit eclectic in my tastes....

I bet the new $6K NAT Audio Single Integrated amp..{the best} would be the perfect match for Cube Audio speakers. Audio Heaven !
