Thank you all for making this event happen. Especially thank you to Albert of Tweak Studio for hosting, and for Ray Samuels for giving me a chance to experience pretty much the pinnacle of Head-fi.
Some impression from an admittedly lo/mid-fi guy:
The RS Darkstar is a stunning amp to both look at and listen to. The LCD-3 and Darkstar combo is an amazing one (connected to a Burmeister CD player) and made the most impact on me. Everything sounded like I believed it should, and it felt like I was in the studio with the jazz singer that I listened to.
I also had the privilege of listening to the Stax SR-009 connected to the RS A-10. This will probably get me burned at the stake for heresy, but like the LCD-3/Darkstar combo better. The top end was gorgeous, and the detail retrieval was impeccable, but to me I like a slightly heavier bottom end.
I also got to listen to the not available yet RS Intruder portable balanced dac/amp with a pair of HD600's. There was an incredible amount of power and detail available, but I think the HD600 isn't the Sennheiser for me. A little too much treble for my ears. I am a bigger fan of the HD650, but unfortunately didn't have an adapter to try balanced on the Intruder.
I was also able to try my personal HD650's single ended from the Darkstar and now understand just how good these can sound. They will never be as quite or detailed as the big boy planar magnetics, but something about their sound signature just feels right for me. Also, I was able to compare my modded T50RP's to the LCD-3 pretty extensively on an ALO Pan-Am. I already liked what I heard from my Fostex's, but now I understand the zeal on the modification thread. I will not claim that my $100's spent so far is as good as a $2000 pair of headphones, but they are damn good and are definitely not $1800-1900 behind. Mine are still skewed towards the midrange, but I like that about them. I am not a neutrality uber alles guy. I want warmth to my music. I still have some more tweaking to go, but I am no longer in a rush to upgrade to better headphones.
I think the best part of this experience, besides now understanding what the top sounds like and meeting fellow Head-fi'ers, is I now know where my current system stands with the context of great sound and I can rearrange priorities. I like my cans enough out of good sources and amps compared to top of the line stuff to the point that I don't need new headphones. I am going to work on improving the other parts of the rig.
Thanks to everyone who showed up and shared their equipment.
