As with most things, I've found it's often better to go directly to the source, so I asked Mr. Quilter about his choice of having the XLR output linked to the Master Control, and he was kind enough to not only thoroughly explain his reasoning, but gave me permission to share it with my fellow TBers as well:

Hello Derek
I visualized the Line Out as driving an external amplifier/speaker or even a powered speaker. Like any extension speaker, I assumed it would be desirable for its volume to change along with the volume settings on the Bass Block.
Philosophically, I am stuck in the old-school theory that performing musicians are the creators of their experience and should have complete control over their sound. For that reason, all output feeds on our products reflect the amplifier’s control settings. I have become aware that sound engineers might prefer a fixed send to decouple what the stage hears and what the audience hears. I can’t argue with this in the limited cases where the audio mixer is a creative member of the band team, or at least an experienced professional with trustworthy musical judgment, but only a small percentage of our user base enjoys such competent help. The bands I go to see fill the club with the output from their own bass amp, or supplement it thru their own PA which is not actively monitored, so they need the signal chain to respond to their amp settings. Even on a “real” stage, the adjustments a bass player might make for stage level won’t exceed the engineer’s ability to compensate, who is probably riding the mix anyway. Anyway, “that’s my story and I’m sticking to it”.
You are welcome to share this.
Best regards
Pat Q

Howdy,
We've been having quite a bit of discussion on Talkbass.com about the reason behind having the XLR line out tied directly to the Master Volume Control, so I figured I'd go directly to the source and see if you wouldn't mind telling us the thinking behind this design decision.
As I mentioned last time I contacted you, I'd also like permission to publish your answer on Talkbass.com.
As a side note, I'd like to thank you for this wonderfully brilliant amp. It's the first class D amp that has given me the full tone of my bass. Just a wonderful gift for us bass players.
Sincerely,
Derek Dean
