I'm of the belief that it's much the same with amps as it is with guitars only maybe a bit more so. Less expensive models will get you very close but lack some of the finer touches and features of the very best money can buy. If those things are important to a guy and money is no object I say go for it. There's nothing like a great amp to make an average guitar sound exceptional. I have a very good friend and TDPRI member who has two 65 Amps models that I believe are two of the finest sounding amps I've ever played through and I'd love to own one. It's just that for me those amps are beyond my limit price wise and I can get close enough for me with those I have all of which cost me less than just one of his 65 Amps models. Play what you like, can easily afford, and what fits your style and skill level. A $2k-$3k amp isn't gonna make me sound any better than those I have.
