When integrated with a buffer amp, its gain will increase the noise figure, so maybe not much difference. certainly not anything that has any real world relevance. All the Purifi amps are astoundingly quiet.

No power figures were confirmed, but considering the supply voltage I was quoted, your estimate of power seems about right.

Yes, I'm sure I can't hear any differences with well designed Purifi Amps.

That's exactly matched with my experience with P422, The Amp already reached surprisingly dead silence with all of normal sensitive speakers, is powered by great low noise PSU and smart design of buffer board including RF filters for real-world performance!

Anyways, seeing Purifi's challenges and sexy outcomes are interesting all the time.🤣

Hi Alan

My I ask a question?
Do you have any plan to use newer 1ET9040BA amps?
😉

Thanks for the response Alan.
