No, I have not listened to the TP 2.2 in my system. I heard it in Joseph's system. As I reported in October, Joseph invited me to listen to the 845 SET amplifier in his system. I did not audition the TP 2.2 at that time, although a TP 2.2 engineering sample was working with the 845 amp, I believe. We'll have to watch for the Positive Feedback review of the TP 2.2.
Yesterday, I listened to an improved 845 SET amp in my system for the first time. I will say more about that event in my next post.
