I'll start this shindig off. Sorry if I'm a bit poignent. :P
We had a very nice small meet at Whetstone Audio this afternoon. I know I had a good time, and it seemed like everyone else did as well. A list of some of the equipment is in the main thread here, http://www.head-fi.org/forum/thread/544253/austin-meet-april-16-2011-3-6pm-at-whetstone-audio There were some notable additions such as a pair of Grado RS-1 and Hifiman HE-5LEs
Like everyone else there I was blown away by the LCD-2 and HE-5LEs that were brought out. I definitely give the edge to the LCD-2 for overall clarity and just plain amazement. The LCD-2s seemed to do everything just right in my mind, even on my Audio-GD Compass, however, the HE-5LE's had an insane ability to reproduce very low bass (they never stopped) which wasn't matched by anything else I heard.
The Lebon CX300 Brian of Whetstone had hooked up for us was amazing as well. Made the HF2s sound better than I've ever heard. As I expected, the amp difference was somewhat minor going up the chain from the Compass, but it was definitely noticeable. I can see how people edge towards the best of the best and eek their way into the super high end if you have the means. I'm now convinced of the last few percent costs exponentially more when it comes to source and amps. Headphones, on the other hand, sound quite different even among the same price points.
I'd never heard the K701 before and have to admit playing classical music (what the owner listened to) through it was very very nice (especially paired with the Schiit Valhalla). It was, however, missing far too much bottom end for me and the music I tend to listen to most of the time. Impressive headphone, but seemed fairly one trick.
The DT770s were quite nice. Very good for the price point, but seemed to be missing some of the midrange I enjoy with rock music. D7000s (which were apparently extremely new and not broken in) sounded very good. Similar to the HF2s in sound to me, but are closed phones which can have many advantages. I've always found open phones sound better for the money, but those were probably the first closed phones I truly enjoyed.
ATH-ES9W were stellar little portable phones. Something I could see carrying around for sure.
Amp and source wise it was hard to really sit down with one and get a good idea of the slight differences. All of the setups sounded very good. It was fun to see everyone and their different tastes of music and sound. People listening to Classical, Funk, Rock, Jazz, Hip Hop, Electronic, etc. Even had a bass head that brought a very interesting little device called the "Portable Subwoofer" that really did make the phones sound like you're at an electronic concert or club.
Overall a very good time. Thanks to everyone, especially Brian from Whetstone.
