Thanks,Bob.
I actually originally thought of purchasing an ALS1300, but simply didn't
have the bucks to do so.
Maybe someday in the future, if I get a big retirement windfall or win the
lottery! (grin)

~Tom,
I used to drive my ALS600 with 60 watts of drive power. Going higher than
that didn't increase output power at all. I did not use the ALC.
With 60 watts of drive, I usually got around 550 watts out. What's
interesting is that with my als1300, I can get 1200 watts out with 40 watts
of drive.
