My intention now is to put the NOS Amperex tubes into the line stage; I'll keep the phono preamp for now. I'm considering strongly getting a pair or two of GL 759s just to have here.

I've been told that a tube pretty much shows itself in about 2530 hours, at least in basic character. I hope to double that before making any big decisions. I think the JJs I'm using now took more than that 2530 to really fill in. I have 3 pairs of them and 2 of the Amperex.
