Having owned my fair share of 'boutique amps' over the years I'm always wondering why builders offer sooooo many different models while each builder has it very own signature sound to begin with. I understand the different power rating and speaker configs but beyaond that are all these different models really necessary? Seems to me the builders themselves are creating their own competition. Train#reck & Dum*le offer 3 models each and no more correct? I guess they understand what I'm talking about.
