Is it possible that the cable elevators -- especially given the positive effect on the mid and upper frequencies -- that simply eliminated exaggerated bass and made the low frequency response more defined and accurate. This might be especially the case for stand mounted monitors which often have a pronounced hump at 50hz to 60hz in order to give the impression of bass impact. As well, you would not be able to hear the loss of a couple of hz of bass. An octave or perhaps even a half octave -- if you are a particularly experienced musical listener -- is probably discernible.
Cable Elevators killed my bass
I purchased a set of 8 Cable Elevators locally on consignment recently for experimentations' sake and was shocked to hear how they seemingly sapped my speakers/system of a couple of hertz of bass output. I have stand-mounted monitors with limited bass so this effect was not subtle. However, every last vestige of grain, haze and artifice in the mid and upper frequencies was gone (and I mean GONE!) as well so this tweak seems to be a double-edged sword that I feel like falling on. Anyone else out there have a similar experience with disappearing bass?
