Hello! Looking to get into the world of tube amps. I was just wondering which of these amps, both of which are available at my local Long and McQuade, is a nicer amp? Either one would be going into an NV610. I'm looking for something to rattle the house, while still cutting through, and bringing a bit of overdrive. I have a few pedals that could help with that in the case of the YBA300, which I heard is quite clean. Another thing to consider - the YBA300 is half the weight, and $800 cheaper. But, those issues don't seem as important if the SVT is that much more amazing.
