Rhmmmm - Nice amp and speaker combo. I too have the V70SE w/black box and Dyn C1 Sig's (upgraded from the originals). Are you using the stock tubes or have you done some tube rolling? Did yours come with the EL34's - 6550's or KT88's? I've done a bit of tube rolling and it can make for some nice changes. The V70SE has a plate voltage of 540V so if you do swap out some tube be careful because some tubes even though have a max recommended plate voltage of 600V are really designed for a more common plate voltage of 450V.
Polk432 Yeah I forgot about how the shelves can slide around. They also had but discontinued some plain rubber feet. They don't slide at all - But the problem with those they don't support very much weight at all.
Anyhow back to cables - I found as your system gets better the cables will make more of a difference. If twice as expensive will be twice as good it won't happen. But I will say the Tyr2 was a great upgrade from the original Frey IC. It's very different from the original. Much better bass and more liquid sounding IMO.
