We already know from another thread that Rodger has never heard, used or even touched a BG-1. So he doesn't know one way or another anything about it, and certainly has no basis for making any kind of judgment on it.
I do agree with the part about not going through extra circuitry if it isn't adding anything desirable. That's just business as usual, anyone using their ears will automatically do that as they work.
In any kind of creative process one of the worst things one can do is be resistant. This kills the work flow, the creative flow, and raises everyone's hackles. If someone comes up with an idea, no matter how seemingly foolish it may appear, it's *always* better to say "let's try it" than argue about what a bad idea it is or why it won't work. It is always possible to be surprised and to learn something unexpected and good.
As far as an external power supply, a lot of really high end gear uses external power supplies. I think many of us are used to the cheap and poorly shielded wall warts that come with budget gear. But an external power supply is actually a pretty good design as far as keeping the audio electronics away from any electrical interference. It isn't as convenient though, I agree with that. I personally do like the power supply inside the unit itself.
