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

I owned a Wright WLA12A which used the 6X5 rectifier. I used both RCA and GE, and I didn't notice much sonic difference between them. However, there was a huge difference in the noise, with both RCAs and one of the GEs generating significantly more noise than the other two GEs. Can't say that's typical; these were all Ebay/Audiogon/friend's tubes, not purchased from commercial tube sellers.

Always wanted to try the Sylvania but sold the preamp before I had a chance. I love Dr. Peppard's stuff and I've talked to him about the 2A and 4A, but WAF and my laziness require a remote.
