I thought about getting DFs as a present after passing driver's exams. Read those very few reviews online, which were generally a mixed back of helpfulness. Then I took the bullet and said, yes why...

Have you learned if there is any change in this sound being produced by changing any combination of feet and the surfaces your amp sits on? Sometimes, when elimination is not possible, minimizing becomes a satisfying and reachable goal.post #5080 of 1492910/1/13 at 8:00ampost #5081 of 1492910/1/13 at 8:54amThread Starter
You may have settled on the perfect placement. But for experimental purposes, try moving the amp onto different surfaces. Why go to the Spa or the Gym? When you could move/pump iron right from the listening room... ask Clayton SF!post #5082 of 1492910/1/13 at 10:20amQuote:
Ultra-, my 300B Glenn Amp mono blocks have a mechanical hum like yours. I've heard yours and it sounds just like mine. Same intensity, etc. I have placed my mono blocks on thick rubber discs (usually reserved for wine glasses) and the sound did not change. Cork didn't help either. I have also lifted the amp off its feet and held it suspended for a few seconds (it is heavy) and the sound didn't change either. I even placed spacers under just the front two feet thereby lifting the front of the chassis at an angle of 1-inch higher than the back--no change either.
Why don't you try putting cork or rubber coasters under your amp to to try it out? Your room is smaller which amplifies the mechanical hum. Mine gets drowned out by the traffic going past my apartment on Pine Street. ;)post #5083 of 1492910/1/13 at 12:20pmA fairly significant number of my audio products will exhibit a mechanical buzzing from the power transformer when the dimmers in my kitchen are on. When they are not - no buzz. Even my Martin Logan sub does this. Not audible at all from the speakers, it's truly just mechanical. And turning the dimmers off solves the issue. It's obviously that the dimmers are polluting the AC in my house BADLY, even to an extent that line conditioners don't seem to block effectively.
So make sure your dimmers are off!post #5084 of 1492910/1/13 at 12:43pm
