Stan is the best of the best in the mod business (My opinion, along with 20+ others ...that I know ...who faithfully use Stan). He is one of the only mod guys that actually develops and implements his own proprietary gain topologies (he is not a cap and resistor swap guy). Additionally, his prices are rediculously low. Every component that Stan has modified for me has been improved to the point, that I know am very skeptical of other high priced audiophile manufactuers' capabilities. Stan has many customers that can afford virtually any product available, but many have implemented his mods/designs instead. If this guy got back into high end manufacturing, the performance of his products would put alot of his compeditors out of business. Have I said enough?
