I do a lot of mods to my gear, which improves the sq performance. Some are : Isolating the transformer within the chassis, which requires removing it, putting damping material along the inside bottom, and re-installing the transformer; removing the power cord, and replacing it with a 10gauge cord, with a selected plug of my liking. These two things alone are, based on what I, and others, hear, create improvements in sq performance. Damping heat sinks ( and the entire chassis for that matter ), is another revelatory improvement in sq. Just as an example, I own two Adcom GFA 535II, one completely modded, and one stock. Night and day between the two...yes, the modded one being quite superior ( and heavier ) in every way. Enjoy ! MrD.
