@sim_audio_nerd,
Thanks for taking the time to post your listening impressions. A number of comments in this thread have touted the Bakoon amplifier as an excellent solid state choice for the Nenuphars. I do feel it’d be really beneficial to hear them with a good tube amplifier for contrast and different presentation. 

The Coincident Super Victory II is fairly easy to drive but needs more power than the Nenuphar. Which can be driven well with a 2A3 SET (3 to 4 watts usually).and a300b (Usually 7 to 10 watts).quite comfortably. With the Super Victory II I’d go with 20-25 watts or more. You have crossovers and seperate drivers to contend with. This is a non issue with the Nenuphar.

I use a 300b 8 watt SET amplifier however my Coincident Total Eclipse II are an easier driven speaker compared to the later model Super Victory II.

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.
