I just got back from Matt's place, which rocked. I agree, the burgers at Turtle Jacks are quite good, as were the fries. I had a great time listening to some familiar tunes, and it was nice to get a good listening session in on a good rig, as I have been living with my laptop, touch, and MX560 buds for the past week. This is the first time I have had any serious time with either the K340 or the K1000, not counting short periods at noisy meets. As seen in Matt's pictures, we were using a Squeezebox transport with lossless audio files, to a Parasound D/AC 1600HD DAC, and a Hafler P1000 amplifier. Both headphones were terminated to spades, and had some fancy wire on them.
I really enjoyed the K1000, and IMO, it is one of the best dynamic headphones I have heard. K340, not so much, though I was happy to have the chance to listen to them a bit. My only slight issues with the K1000 is they were a bit more tipped towards the treble than I personally prefer, though I didnt play with the toe of the drivers at all, and it was the sort of brightness I can certainly live with. They were also missing a bit of the lowest bass, but I didnt generally miss it too much. The K340 are quite different, much slower, less smooth response, and just generally didnt sound too good to my ears. Bit muddy and with an odd coloration in the mids. Forgetting now though, as we listened to them first and I quickly was wanting to change over to the K1000.
