Rk,
I experimented with KT88, 6550, and EL34 with my Prima Luna PL2. I eventually settled on EL34 (and 6CA7). More than enough bass, excellent with vocals. I use Electro Harmonix all around for both the pre and power amp tubes. The EH's sound pretty good, are some of the most economical tubes out there, and definitely are better than the stock tubes that come with the Prima Luna. Before you go down the tube rolling and NOS paths, listen for awhile and learn what you like.
Best regards,
Rich
