I struggled with finding a Pod XT amplification solution for a long time. Tube guitar amps colored the modeler's tone way too much and usually made the patches sound mushy and boomy. Tube power amps were not bad, but usually sounded good only for certain patches. The best results I got were with keyboard amps and bass amps. I own a Roland Cube 60 keyboard amp from the 80's currently, and the Pod sounds really good through that.
i've never been happy with modelers thru tube amps and guitar speakers..... modelers sound best to me thru a PA, a Keyboard Amp or a powered Monitor... something that has a full range speaker and power amp to reproduce the sound banks more clearly
I have tube amps and a Tonelab. The Tonelab sounds best through a pair of full range monitors. Having said that, I've plugged it straight into a cab (bypassing the amp), and it sounded pretty darned good. Not loud enough for stage, but loud enough for recording.
Through my limited experience,I would say it is a bit of a waste:
I tried to use the V-amp 2 in front of the Laney LC15R. I just lost all the dynamics from the tube.
I quickly gave up the idea:boggled:
