I wonder if any co-working places like http://wespace.biz/gallery/ would be a viable option?  Especially if a sponsor was willing to help with the costs! 

It may not take a separate mobile version to provide a good mobile experience...  If the Huddler platform made some W3C-mobile ready tweaks and stylesheets to their BB, they could sell a lot more ads!    http://validator.w3.org/mobile/check   http://ready.mobi/launch.jsp?locale=en_EN  ...

Count me in!! At least two of my co-workers will ride up from Charlottesville with me. Glad to see this happening and happy to help however I can.   We have plenty of mid-market portable gear (Amp/Dacs like Nuforce, Headphones, interconnects/power) along with some home theater components...

I have a fairly new HiFiMAN EF2a with rolled tubes, about 3 weeks old, and it's sounding brilliant with my Sennheiser HD580s and IE8s with an Audioquest Forest USB DAC cable.   I was pretty dismayed when I picked up my headphones and heard a distinct crackling and/or whooshing sound instead...

I just got my EF2a in the mail today, and I'm enjoying the listening test. The provided 110V 50/60Hz -> 16V AC adapter should work in the UK, provided you have a 220V > 120V adapter; perhaps this is what you discovered. 

Quote: ...I have not heard the headsets you linked, but I do know as a commercial aviator, that the FAA approval process adds many dollars to the price of those headsets. Interesting, I can't seem to find any information that says a pilot is required to use an FAA-approved headset...

Quote: ...but I do know that the DT190 is essentially a DT150 headphone with a microphone on it. Looks interesting! I'll have to crawl around to check out how the DT150 compares with other phones I've heard. Thanks to all for the info!

I've recently become interested in general aviation, and have begun the path to get a private pilot certificate. One of the first orders of business is getting a decent headset that's comfortable, durable, has good sound isolation from cockpit noise (either active or passive cancellation)...
