So I've been wanting to buy one more expensive piece of audio equipment before I start saving for college. Since I likely won't bring my speakers with me on residence and am only going to use headphones, it would only be logical to upgrade my headphone rig. I think that I want to build a seperate Stax setup to compliment my HE-400 + JDS Labs O2 combination. I am looking at spending $1000 at the most and I've been wanting to give electrostatics a try. I'm specifically looking at pairing the SR-307 and the SRM-252S with my Audioquest Dragonfly as the DAC. How would this combination sound? I'm looking for something with a great midrange, lots of air and instrumental seperation (but not bright), and textured bass. Kind of like a slightly brighter, more airy, HD-650. Perhaps I would be better off with the Koss ESP950 system, but I want to use a Stax amp because it provides a nice upgrade path if I end up falling in love with electrostatics. Could you guys or girls please tell me what you think?
