Newschool,
Perhaps I can indirectly help with your question....
I'm using a modded Jolida JD100A CD into a TAD-150 Sig tube stage pre into a re-capped Stratos. The Jolida has been re-tubed to Madza chrome plates, the Tad
remains with their cyroed tubes. The Madza's cleaned up the sound dramatically,
speed, detail, with a vast soundstage produced by a very synergistic system. I will not "match" the CD/PRE tubes as each has their individual character and what may work in one component might be unhappy in the other. I have further found that IC's, we use all silver with silver Eichmann's, also have a great impact. Tube rolling will be expensive cause you should rely on knowledgeable high end tube dealers as they will guide you and stand behind their products....a much greater chance of success.
Hope this gave you a bit of insight, good luck.
