It appears that I have to keep this short because the site is not allowing any lengthy verbiage. So, here's the short skinny. The orange amp was fine if all I wanted to do was rock my brains out. It was just a little too one-dimensional. The Marshall, on the other hand, has an enormous versatility that I simply could not overlook. In short it is a Rolls-Royce compared to a 48 Dodge. And right now that Rolls-Royce is really singing. I like single 10 inch amps very much.
