Oh, I do Frank. Townshend Audio Seismic Pods and platforms, Symposium Acoustics and Ingress Engineering Roller Blocks, DH Cones, BDR Cones and Blocks, SIMS Navcom Silencers, Herbies Tendefeet, EAR IsoDamp, tube dampers, VPI Magic Brick, silver ic and speaker cables, Bybee and Shunyata power conditioners and power cords, Shakti Stone, Tube Traps, diffusers, lots of others.
But the assertion that one can change the basic performance of an inherently flawed or compromised design (a power amp, for instance), turning it from a mass-produced mid-fi component into a product producing better sound than a product designed from the ground up as superior-performing one (define as you wish) is laughable. Removing a power transformer from a chassis CAN improve the sound of, say, a pre-amp (Ric Schultz did just that in his mod of the Audible Illusions Modulus), but that does nothing to change the pre-amp’s linearity, overload margin, stability, bandwidth, distortion, gain---the most basic jobs of a pre-amp. The claim that even more minor tweaks than removing a transformer will (heh) transform a pre-amp (or power amp, or, God forgive, receiver) are those of a charlatan.
