First things first. Replaced the right angle plug with a straight plug.
The right angle one is the same plug I used for my T50RP Mk3
Onto the brief impression. I have two other planars, the TH500-RP, and the above mentioned T50RP Mk3. I going to glance over the Mk3's because they are heavily modified (for EDM goodness) and focus on the TH500-RP. The problems with the TH500-RP are the rolled-off treble and limited sound stage, outlined in this review comparing it to a LCD-2 (http://headphone.guru/enter-the-fostex-th500rp-planar-magnetic-headphones/). The M1060 has much better treble than the Fostex. High hats and cymbal attacks are crisp and sharp with a very natural decay. The soundstage is also noticeably wider, with excellent imaging, and is about perfect for my ears. The midrange is somehow even better than the TH500-RP. Vocals are wonderful without any hint of sibilance. The bass, oh man, the bass is where it's at! Much deeper extension, but tight and clear, and no boominess.
The M1060 also beats out the HD6xx, especially the midrange where the Monoprice just kills the Sennheiser.
