To be honest, I'm not much of a headphone music listener. I'm much more into speakers, and all of my headphone/earbud listening happens when I am working at my computer.
A few years ago I bought a set of Sony MDR-1A headphones and I like them. They wouldn't work with the cheap NuForce DAC/amp I had at the time, so, being a Schiit fan, I bought a Fulla 2, which I thought had decent sound for the price.
When the Jot came out, it was something I was interested in, but I kept convincing myself that I wasn't into headphone listening enough to justify laying out that kind of money.
One night a few weeks ago I said WTH, and ordered a black Jot w/ multi-bit DAC card. The next day I had major buyers remorse and was kicking myself for spending $600+ on a computer headphone amp. I looked up the restocking fee and tentatively planned on returning the Jot without even listening to it.
When it arrived I couldn't help but open it up to have a look. I connected it to my iMac, and had a listen.
I absolutely love it. Instead of kicking myself for ordering a $600+ headphone amp, I've been kicking myself for not buying this sooner.
I'm sure there are better DAC/amps out there, but this is a huge improvement from what I was using and I am really happy with it.
