Thanks for having up there, guys. The DC scene is pretty darn active, have a feeling I'll be seeing some of you again.
Some impressions:
ZMF Omni prototype: definitely gave me a closed HD650 vibe with a slight hint of the T50RP treble spike. Pretty relaxing, I'd love to evaluate this for a long period of time
R70X: this is an interesting entry in the HD600/DT880/Q701 market. It seemed a tad hazy in the upper mids, but I could see it being pretty darn good out of a resolving tube amp
HE1000: Pretty resolving for a planar, and huge soundstage. I don't think I quite enjoy it as much as the HE-6, but it's pretty enjoyable signature wise.
Liquid Carbon: has a pretty lively, warmer solid state sound. I quite enjoyed its pairing with the Ether C, think it played well with that headphone's signature the most. Sometimes I regret cancelling my preorder....
Ether C: Seemed to be an improvement over the Alpha Dog/Prime line, and a pretty solid closed back. It was maybe a tad hot in the treble, but the LC pairing seemed to do a lot of good for this headphone. Nice wide soundstage, and it did Take 5 plenty of justice
Krell Clone: didn't catch the owner's screen name, but this thing was awesome. Reminded me of the Audio GD amps, authoritative bass for days.
Modded TH900: I was surprised, this modded pair seemed to fix some of the midrange issues I heard in the stock form (I'm not too fond of the stock version myself). Definitely an improvement to my ears, well done!
Pinnacle P1: Very interesting IEM, and takes a load more power than you would think. Loved the build quality, especially the cable and the tips. The sound felt kind of mid bassy and warm to me, and there was a tiny bit of mid range haziness, but it was a pleasing listen overall. I'd be curious to see how these perform with foam tips. The owner of the P1 was an awesome guy, too. Sick DIY tube amp!
