@voltaicq I think I may have overstated the can't afford it element. I can't afford it at the moment, but I probably can afford it in 6-18 months if I focus on saving. I think the real element is I can't afford to change the amp AND make other changes in my system really would be of more benefit.
And the core thing I was trying is that amps constantly capture my curiosity, even though I am happy with my existing amp. I'm not one to collect a lot of equipment. I like to have one system that has all my resources put into it. But I have a feeling I may become the type of person that ends up with 2-3 amps over the years because I am constantly curious about trying new amps more than other piece in the system.
