On tube I thought the stock tubes did a really nice job, but I did upgrade to NOS Telefunken ECC801's. A bit more refined sounding.
Power cords can really add something to the party as well, I tired an Actinote (slightly better than stock), zCable Red Lightning (worse than stock), and ended up splurging for a Shunyata Anaconda Alpha Helix (big time improvements).
Then lastly on isolation, I went with a Silent Running Audio VR series isoBASE 3.0. I thought the base took things to another level in particular with the bass. But also some other areas. It is not the cheapest isolation method, but I feel it was worth every penny. Now I just wish I could afford a pair of these to go under my monoblocks as well. But yes teh rumors of you needing good isolation beneath the player are true.
