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

For Cal; and others who may be interested...

Here are some of the general differences between the custom 2A3 build by Scott and his former, my current, Found-Music 2A3 amps:


* 4 chassis design, heavier construction vs. a 2 chassis design

* DC regulated filament/heaters vs. AC heated

* driver circuitry and theory is different, now actively loaded

* driver tubes are mirrored vs. a single tube

* active regulation in PS

* amps will be prioritized for signal purity and performance...amps I have were designed to prioritize output power

* high purity silver cabling throughout vs. copper cabling

* Different and ’superior’ output transformers


I’ll update as the build progresses.

Sounds great David. Would love to hear them, especially with the Nenuphars. As Charles said, I'm sure it'll be an amazing pairing.

Hi cal,
Looking at those design parameters and build choices/decisions for these new 2A3 amplifiers, Scott  is pushing for the absolute pinnacle of SET sound quality.  David is going to be astonished with the completed product. 
Charles 

Well said Charles. These are the times where I wish that this community was smaller (in terms of geography). So very jealous and I'd love to ride the coattails and listen along with you David. 

What preamp do you use with the SIT-3?

I am very happy using a Backert Rhythm with NOS Mullard 12au7 tubes. The SIT-3 also sounded great with a Pass XP-12 which I borrowed.

I was trying to see if I can simplify the setup with an integrated.

Have you looked into the Bakoon 13R?
