That is a good heck of a list of 6SN7 preamps where one can be happy with any one of those.
As for me, I am using an Aric Audio preamp(close to the Motherload II build, but not quite) with my Pass XA-25 for at least 18 mos. or more now, and there’s no changing to anything else for me! Can’t compare the Aric to anything else on the list, but it betters any other 12au7 or 6922 based preamp I’ve used in the past. 6sn7s are the real deal for preamps. I can get great music out of the Aric with a whole slew of 6SN7 and 5v regulator tube combinations… many flavors of sonic bliss can be created!!
