Looking for Tube Pre-Amp Recommendations

Just got a pair of Avalon Ascendants and have them mated with Sonic Frontiers Power 3 monoblocks and an old Conrad Johnson PV 12 pre-amp (will be upgrading my old Meridian 508 cd player too but want to settle on the pre-amp first).

Looking to upgrade the pre-amp as the Avalon's are either showing up the pre-amp and or it's just not a good fit (it worked well with my Thiel 6's). So, looking for a recommendation for a replacement tube pre-amp. I'm fine buying used. Don't want to spend more than $5,000.

Curious if anyone knows the newer CJ stuff? I liked their sound years ago and it worked with the Thiels but now curious if a better more recent CJ pre-amp (like the CT5) would mate well with the Avalon's? One person told me he didn't think it was a good fit (he thought the new CJ's were "pudgy" sounding and not quick and airy enough for the Avalon's).

Any thoughts would be most appreciated.
