Would like some opinions on tube rolling

My AudioNote preamp uses two 5687 drivers and two 6x5 rectifiers (I think that's what they're used for...). They are all Phillips. I would like to get a little more bass and mid-bass oomph. The unit is extremely detailed and transparent currently. I'd be willing to sacrifice a little (very little if possible) of that transparency to get the added warmth. Since many here have had good things to say about interactions with Upscale Audio I sent off an inquiry to Kevin, but haven't received any response from him yet. When I do talk with him, I'd like to have a little more background as to the possible alternatives and some input from those who have actual experience with the subject.
Thanks for the input

Toguht I would revive this old thread as the subject matter I'm interested in seems rather esoteric - 6x5 tubes. I've order some from Sylvania, RCA, and GE. Any fols familiar with the differences between various 6x5 alternatives and how much or little they may influence the sound a rectifiers for a linestage.

Yup, got a Sylvania in there now, and seems very quiet for a tube linestage, though not as quiet as my passive:). I love the MT 2A, a very thought out product with zero BS factor. As good as my CAT, Lamm, and Joule Signature Edition? Hard to say since I don't have them for a/bing, but I don't feel I'm missing anything, though I would say the Lightspeed Attenuator is still the best "preamp" I've heard with my amps and speakers. I'm going to stop worrying about the 6x5s, but 12sx7???

Where did you find the 12sx7s? Dr. Peppard seems to really like that tube.
