ECP Audio T4 headphone amplifier looks very interesting. It’s a tube/transistor hybrid design.
Its measurements could be very interesting considering the circuit topology and the claims made in the ad copy:
“For those of you familiar with ECP Audio designs, the T4 is a tube-fed DSHA amplifier!
Why a fully differential circuit but single-ended on the output?
Answer: Because circuit/device distortion is fully cancelled out by the solid-state output portion of the circuit. At the same time, combining the solid-state output with the tubes results in more power than would be available simply from the tubes. The output transformers assist with this, ensuring that ample current and voltage are available, regardless of the impedance of the load.”

Well, the 3F was measured on SBAF https://www.superbestaudiofriends.o...cp-audio-dsha-3f-technical-measurements.7509/ considering it is the solid state version of the T4, the latter one will probably perform ((even)) worse,
I mean these amps are powerful so they'll surely sound good with most headphones. But those output transformers are really little distortion machines. Pleasing, maybe, but distortion all the same.
You know how tricky it is to lift this massive, tall and very slippery speaker up 5 feet to put it on the measurement platform that is currently only 6 inches square? If you were me, would you risk $12,000 to satisfy your members?I want a review of: Revel Salon2.
It would be super useful, though, if there were a sage and practical way to do it. The Salon2’s are lauded as one of the top speakers on the planet and I know many would like to see how they measure on the bench!You didn't have to delete it. I was just noting that it is not something I like to do anytime soon.
