If you are not already using a Siemens 7308, maybe you should try. My brother have the same CD player (with the same OP-Amp upgrade) and his sounds very detailed and articulate. Soundstage was bigger too compared when he was using a Jan tubes.
Also, on my own experience, try a Nordost IC or speaker cables, or a Silver type interconnect like what Tireguy suggested. They are very good in giving a "bright" edge to any system that I hook them up.
Hope this helps
