Graham Slee is an odd duck, however, he really does tune some very musical amps. Still, the price point strikes me as high. If it takes him that much time to refine and tune the designs he will have to eat more of that time as an unrecoverable expense. I get the feeling that the price reflects the belief that all of his tuning time was billable. Regardless of how you cut the cake, it is a simple box, with fairly simply parts. Sounds great, no argument, but that is far too expensive. Hell the Gustard U12 will give it a run for $399.
