I'm still loving the PSB-M4U2 bigtime. I'm listening to Lalle Larsson ' s Weaveworld albums alot on them as well as a group called Trioscapes and another group called Stuck Mojo and everything sounds absolutely amazing on them. But, I'm noticing the mids don't have that upfront crunchy grinding sound I'd like a bit more of from electric guitar sounds. I've always heard of Sennheiser headphones be accused of having something dubbed "the Sennheiser veil" and I'm wondering if the PSB have something like that as well.
I'm hoping to get some Grado SR60i soon to get a bit of a brighter more open sound for certain types of music.
