I'm with you. My version of nick n's MemFoam Mod sounds good, to me. I don't hear Boom, sizzzzle, or distortion, FWIW. We all have different "ears and gears," though, so there is no "Right" or "Wrong." You like something, or you don't...'nuff said. My "nickerfized mod" version sounds great out of HA-1 and GS-X mkII amps, with HA-1 DAC and Meitner MA-1 DAC.
