Bass quality of SR-007 MK 1 - my observations.
Now that I have a pair of the Mk 1's, I have some comments on their bass.
They go very low. They have pretty good "impact" or "slam" however you want to put it. Not as impactful as better dynamic or planar headphones, but very good. OK, for this kind of money you'd expect that.
On top of these commendable qualities, there is something different about SR-007 bass, as compared to my other headphones.
There is a kind of "roundness" to the bass - a "tuneful" quality that is a little more prominent in the 007's than in other headphones I have. Perhaps a little mid-bass emphasis, coupled with very high resolution and accurate decay so that the little bit of extra mid bass doesn't create a "bloated" or "wooly" sound? Or is it just that the rest of the audio spectrum is so evenly presented that concentrating on the bass line becomes easier, with the ear not being distracted by some shrill high frequency peak, midrange ringing or other flaw that my other headphones have?
The bass has a very nice "organic" sound. There is tautness, bass detail, texture and all of that. but there is complimentary warmth as well.
I really like these headphones! I like the MK 1's much more than my previous MK 2.5's.
Note: using them on SRM-T1 for now, which sounds quite nice. They seem easier to drive than the SR-007 Mk 2.5's that I had. No doubt a better amp will sound even better....
