Question's I ask are, how much better are these compared to the M2C's, if there is an improvement how much more ?, and does this improvement justify spending another $100.
How could anyone justify any purchase after the $29 M2c? It even makes the $25 MX580 looks positively a waste of money.
But then again, if you consider TM7 sounds better than PK1 for almost the same price and can go without an amp, then you'll know the asking price isn't outrageous at all. Yes, not nearly the bang of the buck as M2c., but that doesn't mean it is a bad investment at all.
