For the "whatever it's worth" dept....
Re headphones, SQ in general, I'm pretty happy with the SONY MDR 1A's with Audioquest Dragonfly Red feeding them, BUT, here's my critique on SQ, and why I prefer GET sound to anything else I hear on headphones, HT systems, car audio etc. etc.
Treble range: For whatever reason, my ears are sensitive to harsh sounds in this range, and usually on other systems I turn down the treble to avoid harshness at volume. The HVFR tweeters are the first tweeters I have ever heard that not only aren't harsh, but are SWEET, SMOOOTH at any volume! I agree with T Cobe, GEt's tweeters are the best!
Mid range: lots of high end systems, including the SONY headphones, are clean and clear in this range, but I find with the GEt's a some richer sound. Others can sound a little clinical, as opposed to musical.
Bass; Ah, bass. Again, the SONY, and other systems, have clean bass. But, GEt's have a degree of richness, musicality, I just don't hear on other systems.
So, Moderator Dude, when the engineering team is through developing headphones with HVFR technology included, you have a bunch of people not only willing to buy them, but to "test drive" as demo's even before that!!
Keep up the good work, GEt!
