I love my M50v4. I was listening to them this morning in 2.0 with my cassette deck plugged directly into my ADA-1000. I was taking a break from my active LFR1100s with five sealed Axiom subs, and 12,000 peak Watts of Axiom amplification. I was taking a break from my M2OW, M5OW and EP125s too.

To sum up, I was taking a break from the higher spatial resolution and fidelity offered by the Axiom models that have (a) dedicated mid-range driver(s) and returning to the laid back standard definition of the M50v4.
