Where to start, other than to thank our most gracious host, Rob, aka Bahamaman, and the generosity of TCU for the use of a well powered lab. Mayhaps the tiered desk arrangement hindered mixing a bit, but gear, ideas, and opinions were mixed well, and in a civil manner - well, except for the absence of the gear being brought by GS...
Everything here is my opinion, and what I like (or don't).
I'll be brief in my opinions and bias. I now have thoroughly dismissed Grado as a player in my world, though I'll still recable my 225s just for a change of presentation, but not for serious musical joy.
Headphones:
Grado RS-1: No, but I see the attraction to the presentation.
Grado PS-1: Just no. Simply not for me, and, surprisingly not better than RS-1.
Beyer 880: Surprisingly hard to drive, but probably the closest to the Senns (and my liking).
AT900 - had a high frequency ceiling, and really bright
AT1000 - close, but just a tad too bright - but I could learn to like it
Sony SA5K - this is a contender, especially on an amp with a bass boost
AKG K1000 - interesting, and my first exposure to electrostatics - but, alas, the m³ simply would not drive them with any authority
Senn HD650 - Yes. Even with the stock cable, but better with a Dragon.
HP3000 - Joe Grado HP drivers, enclosed in a Sony MDR-CD3000 shell, recabled and woodied - YES. Very sweet.
DAC:
Ok, this is something I am just not onboard with just yet - maybe it's that the C222ES has an acceptable DAC, or I'm just lagging (known to happen), but I listened to 2 for sure:
Benchmarkl DAC1 - smooth, refined, but better than the dac in the Sony C222ES or the Meridian 508? Not sure.
CIAudio VDA-1 (with VAC-1 Power Supply) - Wow! I liked this DAC a LOT. More of everything, but I can't say whether it is any less defined. If I go external DAC, this is the way I go, given these two options.
Source:
I'll only go with the Meridian 508, since it is the only one that I paid attention to - my next source upgrade (though that is gonna be a while).
Amps (what we all really came for anyway - except the R10):
Disclaimer: I need amps - measured in horsepower - others will clarify.
I wanted to shoot it out on a Dynahi, which no-showed. Life goes on.
m³ - Others will have to comment
Millett Hybrid - ditto
Wheatfield 4 (warning: full Senate filibuster coming) - guys, seriously, I'll just quote Ray Samuels: "With this amp, what else does anyone need?". As impressed (and I spent easily 2 hours with this amp) as I was, there are no better words to describe it. It was designed 6 years ago, and can use some tweaks, but the sound - the toys (potted 4-13db EQ in low-mid-high, 3 position crossfeed, and a defeat switch) - pardon me, but G_d Almighty, this is THE amp that needs resurrecting. Only 5 were built, and it absolutely ROCKS. This is the amp pete built - and the professionals have been seperated from the taxpayers. Period.
Ray Samuels Stealth - OK, it was clean, and nice, but wimpy for me. Not enough output.
RS Hornet - Ah, Ray requested I take on the Hornet, but, alas, I was not stung. I'm not a portable guy, and found it, again, lacking power. I took it to 10, but needed about 15. It will be awesome for probably the entire balance of the population, and is a wild bit of microelectronics. But, again, I need juice coming out of the wall, with no warts between it and me.
RS Raptor: Ray is quite a charming man, who is a giant in headphone design stature. Know what? Call me Prometheus, because the Raptor picked my bones and left my body parts strewn all over the rock. Un freaking believable. I was able to crank the Raptor to no further than a little over 1 o'clock, and thought the HD600 would literally shake apart. The entire room could but look on in horror, point, gasp, and had cell phones predialed to 911, just waiting to punch the call button. Never, ever, have I heard bass like that - secondary bass vibration from the earpads literally vibrating off of my head. Nothing I have ever experiended was that LOUD / great / controlled in energy and FURY. That is what the headphone experience is about. Thank you Ray - THAT is the only thing the HA4 didn't have - blind, blasting fury. My wife hates you already - and I'll gladly sign the waiver form before buying one.
I spent approximately 7 hours in the room in Ft Worth, mingling, chatting, listening, and celebrating what we all share as a hobby. Odd, is it not, that we would have a fellowship to do as a group what we each, by definition, pursue as a solitary passtime? Nonetheless, a great time was had by most, if not all, and I'm sure many were entertained (or annoyed) at the VOLUMES in which I was enjoying everyone else's toys.
Mayhaps, next time, we DO get a seperate room for the more obnoxious among us - and hopefully, I won't be the only one in there.
To everyone, thanks, I really dug it, and if we didn't talk enough, we'll make it a point to do better in that regard next time. The most fun, to me, other than shaking the building with a _little_ volume, was talking design with Ray Samuels AND Pete Millett, at the same time. Those are the things that just don't happen every day, and thank you both for being lucid, open minded, and giving of your time.
Again, Rob, it was a blast. Literally - the ringing is almost gone.
