Well, from my own persepctive, it went well.
When you have the desk next to you, you're not going to have a bad sound.
I have to say that the Spector through a couple of 1.2KW crown amps and some [url="http://www.logic-system.co.uk/"]http://www.logic-system.co.uk/[/url] pa cabs has never sounded quite so mighty.
Plenty of clarity, voice and endless depth. I was utterly surrounded by my sound. I had a little back through the monitors too whcih helped too, no doubt.
This gives me a problem.
How do I square my amp wants / amp needs ?
Don't get me wrong, I'll never not have an amp, there will be times when I won't have that PA to rely on, but it' certainly clear now that with that much firepower in the FOH, you can gig pretty much anywhere with no amp.
Incidentally, I used no sansamp or similar. This was bass right into a line input of a Mackie CFX12 with the input clipped and the eq dead flat.
