Forky - I see that you're running a Prima Luna Evo 300. Beautiful stuff. I just wonder if, before undertaking all the efforts at sound treatment, etc., an amp change might be "a" if not "the" solution? You know where I'm going.... I find the GanFets sweeter, purer, and truer, tonally and timbrally, than tubes. When you can try a GanFet product at NO COST (other than shipping) for 15 days, what have you got to lose other than, potentially, bias, predisposition, and tube related anomalies?
