Markwatkiss,
Joseph has been spending a lot of time improving his interconnects and power cord offerings. On Friday, when I purchased a digital cable from him, I asked about the power amplifiers.
He has been listening to the 845 amplifier in his system for many weeks now. He is playing with the other tubes in the 845 complement. I didn't get definite information; I did not listen to 845 amp when I saw him that day. Rather, he demonstrated the improvement in the digital cable, which led to the purchase I mentioned above.
My impression is that he is pleased by the 845 amplifier but not satisfied with the development yet. The other two power amps use EL 34 and 811 power tubes, respectively. The EL34 development work is finished. Joseph indicates that he does not plan to make any more changes to it. The 811 power amp is the furthest from completion. My impression is that Joseph will finish the 845 before returning to the 811.
I don't know when Joseph will offer to sell his power amplifiers.
