What would you upgrade next if you had my hifi ?

Oh , one more thing Elevick , the center of the TV is level to your eyes when your seated on the sofa . One vidiophile friend commented that it was perfect .
I did have a vinyl rig until a few years ago , sorry I just prefer well set up digital .

I noticed right away that your TV seemed to be at an optimal height. I'd say the vast majority of screens are mounted way too high. Nicely done. Of course, nice system too.

amp and speakers would go, if it were my system. a planar would replace the revels and a nice tube amp would replace the levenson amp.

i can't comment on the digital front end.
