A tade more briteness - Jolida 302b. Tubes?

I have a Jolida 302b, a Jolida CD player and Tyler Ref. Monitors wired with Signal Cable. I am looking from a bit more treble, briteness, highs whatever you want to call it. A little more sparkle. Will tube rolling help with this? Suggestions please.

I have settled on the the following combination after much experimentation with current issue tubes.

Svetlana EL34 (also tried Mullard, JJ Tesla, Mesa Boogie, Chinese stock)

Tung-Sol 12AX7 (also tried Ei, JJ Tesla, EH, Sovtek)

Mullard 12AT7 (also tried JJ Tesla and EH)

Extension, detail and image are now the best I've yet heard on the 302B.
