Many thanks to purrin, Questhate, CEE TEE, shipsupt, and Anaxilus for making this great meet possible.
The Stax SR-009 (thank you jazzfan for letting me try them in my rig
) was the highlight of the meet for me. They were a bit brighter and more open sounding than the SR-007 mk1, but they do not make sibilant recordings sound worse to me. They did sound a bit harder and not as smooth as the SR-007 mk1, but I think I prefer the sound of the SR-009 overall. Just as importantly, they are probably the most comfortable Stax headphones I've tried.
I had high expectations for the Eddie Current Electra, and the Electra certainly delivered. Like the BHSE, it provides a significant improvement for the SR-007, making it sound more effortless and liquid. I also really liked how easy it is to bias the output tubes in this amp, with the integrated meter and knobs. Unfortunately, there was no BHSE or DIY T2 for comparison at the meet.
Purrin's modded Jade sounded great out of the Electra. They were so much better than what I remembered, I figured they must have been modded before Craig told me that they were purrin's. I didn't spend too much time with them, but they sounded world class (SR-007/HE-60 level) to me.
I didn't like the SR-007 mk2.5 (SZ3 serial number) as much as the SR-007 mk1. It's like Stax tried to make the SR-007 sound more like the SR-009, but they didn't get it quite right. They also sounded a just little bit sharp/shrill to me. Still very good headphones though.
TMoney and Horio's KGSSHV builds looked great and sounded great too. I wanted to try my SR-007 mk1 on them, but I didn't get around to it.
The Ferrari headphones sounded surprisingly nice, especially the active noise cancelling model (since active noise cancelling headphones don't usually sound good).
Ringingears' Project Sunrise amp looked very cool, but I didn't listen to them since time was running out, and there was no good way to get my music on the system.
I wanted to try the Gungnir->Mjolnir->HD800/LCD-3 rig, but I couldn't figure out how I was supposed to add my music (which I had on a USB drive) to the iTunes playlist.
