Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

but maybe I need to get over my "tube fear".

Low power SET amplifiers are about as simple and straightforward as can be. Very few tubes (Or parts  count in general) in these amplifiers and the DHT tubes have pretty good longevity. Also many of them are auto bias designed or simple manual bias. Overall this niche of amplifiers are exceptionally low maintenance. Nothing to fear in my opinion.

@wyan001 I haven’t been able to, yet.

Hi, has anyone got the chance to compare Voxativ vs Cube top model?

I would like to as I’m interested in what Voxativ offers. BTW, I was actively considering Voxativ but chose to go with Cube Audio.

You probably know this, but in case you do not: Srajan Ebaen of 6Moons has extensive experience / exposure with Voxativ and yet the Nenuphars moved him in a significant way.

No speaker does it all and [certainly] they do it differently for each one of us. I cannot see going wrong with either choice.

This is true.

Glad to hear positive feedback on the Bakoon 13R. As said, the amp can be operated as an amp only or integrated with its own volume control. There are a limited number of switchable inputs. I choose to run it with just the Bakoon DAC connected via BNC and it makes for a very compact set up. The Bakoon DAC is smaller than the amp. This is feed from a Fidata server.

I could understand if this statement was refering to a choice between Voxativ and Feastrex Field Coils. 
Here the 2 speakers are completely different construction. 
They most likely will not sound as competitors.
