Line Mangnetic CD player 515. Tube rolling .

"Line Mangnetic".   Hahaha. Sorry I can't edit the heading.

Hi team... I’ve bought a cd515 and it’s fantastic. It uses 6KZ8 tubes in the output stage. I have some Nos RCA knocking around and I wondered if anyone has made any improvements to their player by tube rolling. It sounds very good with the stock tubes and I’m happy to the point where I may just leave it alone. Unless of course someone has different ideas.... Thoughts please.

Thanks very much.....
