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

For the past nine months, I’ve been thinking through and processing possible amplifier pairings for the Nenuphars. Came close to acquiring: Audion Golden Dreams, the New Audio Frontiers 211 SET, Ayon Crossfire/Vulcan EVOs, EM/IA 50/300b, etc.

I made a choice of designer/builder a couple of weeks ago and committed to the specific build today. After one heck of a journey across brands, a variety of power output tubes, SET vs. Parallel vs. Push-Pull builds, etc., etc. I ended up very close to home, in amplifier speak.

I’m moving forward with a custom 2A3 build by Scott Sheaffer (Found-Music). This build will ’make less power in the zone’ than my current Found-Music 2A3s (2 to 3 watts vs. 3.5 to 4 watts).

Second finalist was the Thomas Mayer 300B multi-chassis build.

The amps should be in system by February / March.

A number of members helped with this. THANKS to all. You know who you are!!!

Congratulations David,
I know how much thought,  research and time you've devoted to this search and decision. In my humble opinion the end result for you will be extraordinary sound quality and music reproduction in your home.

Sounds awesome David. Congrats!

Can you remind me what your current 2a3 model is and how the new build differs?

Thank you, Charles.

@cal3713   Thanks! I'll put together a proper summary of differences, etc. and get back to you.

Some high level differences: 2 chassis vs. 4 chassis. Copper vs. Silver wiring. Different output transformers. AC heating vs. DC heating. Etc.

Great, thanks. I've been following Mike's speaker journey recently, so this is great context.
