Personally, I have never heard one, but I get the impression Nutube's are not anywhere near as good as proper tubes working on high voltages. The classic dual-triodes, 6DJ8, 12A*7, 6SN7 etc, still win IMHO.
What is that impression based on?

For me, the ideal would be a switch that allows switching between two types of harmonic profiles. Better yet, a VSTplugin. Having two systems complicates and makes more expensive ALL.

I really must build one myself one day soon. I might be pleasantly surprised (or not).
@jalejos
I read that a few complained about an excess ofmicrophonemicrophonic noise with the Nutube vs traditional tubes. How have you solved / minimized it?

Audiophonics just put on sale a new fully assembled stereo power amplifier based on dual purifi boards powered by an hypex SMPS1200. price is 1500€

A properly designed 12AX7 or 12AT7 circuit will have vastly lower distortion,
An examination of the device characteristics. The NuTube is clearly made to cause distortion, and has insufficient gain and transconductance to correct this.
Sure, but isn't that the whole point of the exercise?
That depends on one's design goals and esthetic constraints. Personally, I enjoy getting high performance out of anachronistic technologies.
Wow! I want one. Glad there's no boutique opamps. Interesting how their buffer performs vs EVAL1 board?Audiophonics just put on sale a new fully assembled stereo power amplifier based on dual purifi boards powered by an hypex SMPS1200. price is 1500€

Stick a 2-8 ohm resistor in series with the output.
Maybe the "Science" in the forum name is a hint?
Don't worry, you can swap the original opamp to your boutique DIP8 opamp later.Wow! I want one. Glad there's no boutique opamps. Interesting how their buffer performs vs EVAL1 board?
