Hey Scriptor,
FWIW (and since you asked

), I've played with all the possible iterations: balanced, unbalanced, balanced into matching transformer, straight into PA, through a DI w/o preamp, with a preamp, EQs w/o preamp...
My bottom line is if you can get the tone you want and nothing else unwanted (like hiss or hum), then whatever the method that gets you there is good. And if you can get the
same sonic results in a
simpler setup, then even better. So having tried all the above, I've arrived at a regular guitar cable (albeit a good one), straight into a Baggs Venue, then into the house. Done, easy, and sounds great.
What you get from going with a balanced signal is better signal-to-noise ratio, an unhampered signal over a long cable run (say, longer than 20'), and better noise rejection (if there's RF, noise from lighting, or whatever). But if you get equally good performance, then I always opt for the simpler setup.
