This severely restrict the range of musics good for the srh940. This would mean they are mostly good for classical ?
I like them for industrial too (nine inch nails, rammstein, marylin manson...). I could also include massive attack which is kind of electronic trip hop.
So what, for you, offers a "good synergy", and at an affordable price (<300$) with the srh940?
If you mean the "transient response", sometimes it seems to me that it is exaggerated (at least with the xonar stx) to the point of sounding sometimes artificial. It's just like a picture that is over-sharpened : it looks more detailed, but it doesn't look natural. Coming from the hd595, to the srh940, is a shocking experience, I was used to something smooth, and now I have something intolerant to anything just a bit harsh. At the end, I think I prefer something that offers some nice euphony, i.e pleasantness of sounds, rather than an emphasis on details.
