That's a great song + video!! Creative, and definitely captures the nature of our disease.
I will say, if I got into speaker rolling like that, I probably would've been burned out of this hobby years ago. It totally shakes up the whole system balance and then you might have to swap EVERYTHING all out again. Picked Tannoys early on, stuck with them, and have been happy. I roll everything else like mad, but having the speakers "anchored" gives me a shard of sanity.
When I did change speakers - even from one Tannoy to the next Tannoy up - that dove me absolutely mad for a long time trying to dial in the system again.
