A question or two about the MAMs.
I have the A12s with standard-issue Auto Modules. I'm not currently listening to them because they are too bassy; the sound is cluttered and generally not very pleasant.
It is my understanding that the membrane in the Auto Module absorbs the pneumatic pressure in the ear canal, and I'm interested to know what the MAM does differently from the Auto Module.
Assuming the membrane inside the Auto Module is a fixed 'tightness', does the dial of the MAM make the membrane looser and tighter than the Auto Module? To what degree? Is the Auto Module fixed at, say, 50% of the MAM's 'looseness'?
Finally, am I correct to assume that turning the MAM 'open' doesn't let in air, but only adjusts the membrane?
Any answers/thoughts gratefully received - I'm itching to get my mitts on the MAMs to see if they 'fix' my A12s!
