Bobby, I am a huge fan of your speakers, my friend Dr. George has a pair of VSMs + BAM and he is very happy.
I would like to point out that not all tape loops are optimal, for example the Audible Illusions Modulus 3 preamp uses a 50 cent op-amp as a tape loop buffer. I do not recommend wiring a BAM through THAT loop, it would degrade the system's sound. The AI's tube outputs sound much better.
On the other had some Jeff Rowland preamps and a few upscale tube preamps use output transformers, which reduce noise and provide a very symmetrical balanced signal. Technically, connecting the BAM to an output transformer should sound cleaner, due to galvanic isolation from preamp / source RF noise and better output signal simetry, specially when using the balanced BAM.
These are exceptions...in general your advice to use the tape loop is a solid starting point.
Best wishes
Carlos
