I can write something , when time permits
I can even make build guide , after that
regarding B1 vs. B1 v.2 ....... there is no fair comparison , just because Pa needed to include series output resistors in both of them , as idiotproof part
both will work better without it , when heavier load is in question
while difference in sound , when load isn't critical (v.2 having half Rout of v.1) is certainly matter of taste

Can competent DIYers remove to improve the sound? Which resistors?

This cool schematic can be found in the middle of two threads.
I though it should be easily found.
Good idea.
I have built both the R1 and R2. I much prefer the R2 version. I use the R2 version for my FW builds not needing any gain from a pre with my horns. An easy perfboard build. I will add the voltage recommendation of Papa as being a 24V switcher which I am using without noise. If you are a follower of the philosophy of less is better than this in theory should leave less of a sonic signature than say the BA-3 pre. I also have the BA-3 pre and I can enjoy it's sound as well. Right now I lean more to the LSK pre for a pre with gain but it is probably more of it being a newer build. Builders have a tendency to favor a new child, at first anyway.

what can happen ?
- Builder accidentally shorts an output to GND
- Builder uses shielded but slightly capacitive cable.
