for the lengthy and very civil response. Try upgrading your coupling capacitors from whatever they are now to something better. For example, if your device uses metallized film caps or electrolytic capacitors, in the signal path, then upgrade to true film and foil capacitors of high quality, say polystyrene or teflon. The difference that will make in sonics will dwarf anything possibly due to changing chassis screws. And it's a much easier thing to do.Further, while I don't believe anything is achieved by replacing ss screws with plastic ones, except a loss of structural rigidity, my main problem is with the idea that because we have electromagnetic theory on one hand and ss vs plastic on the other, the aural benefits one imagines are ascribed to something having to do with electromagnetic theory. Have you or has Unclestu actually measured the EMI in and around an amplifier before and after the screw replacement? If so, is there any difference? That's what I would like to know before I connect A to B as cause and effect.
It's probably not a good idea to use Sam Tellig as an authority on excellence in audio equipment, as Sam himself takes pride in being "the audio cheapskate". His systems are never more than mid-fi, which is fine for him and anyone else with a limited budget or limited aspirations, but not a benchmark, exactly. The LFD LE4 is a small solid state amplifier module which offers the primary advantages of small size and low cost, is it not? What makes it so great? I know of one guy who used it or tried to use it as the core amplifier of a turntable motor controller, where it's only used to amplify the set AC frequency of the controller. (I may be thinking of another device, but that's what I remember about it.) In amplifiers, I don't do solid state except in one of my two systems where I use a vintage Threshold amplifier to drive woofers.
My bad. LFD LE4 is an expensive integrated amplifier, not a cheap module. Sounds interesting.
