These are working very well in my Audible Illusions Modulus 2c - very well indeed! This wonderful preamp is VERY demanding of its tubes - they have to be low noise and have very low microphonics. These tubes are both those things. For what ever reason, one had to have its pins tweaked in order to fit firmly in the socket - this may be the socket, though.

The overall sound is excellent - with good, clear extended highs, but still very well balanced, bottom to top. Soundstage is wide and deep, when the recording is good.

Recommended. I will find out how they last, but they are starting out very well, indeed.
