Hi Jim,
I will share what I can, which will not be much, my experience with the TU-717 was very little.
The 717 I had only worked on channels above 100, I did fix this later, but because of this I only used it for a very short time. Playing on memory, I think the 717 was a little more open (airy) than the T-2, maybe a bit firmer bottom end. I really like the T-2 b/c of its size, appearance and features, but would gamble that the 717 is a little better, not to mention the 717 is easy to upgrade as you are doing.
In stock form, how did you feel the 717 compared to the MD 108 and Classe? I suspect the 717 modded may be hard to beat.
