Hi, Downunder,
Yes, I think you need to roll the tubes to get the best possible sound. The character of the sound changes a lot with tube rolling. Not that it is shabby in stock form at all, it is just capable of a more lucious sound. I thought it was lean at first, but after tube rolling and listening, I realized I just hadn't heard that level of fidelity before and now use it for preamp as well as amp. Vettrone's recommended tubes are spot on.
