Actually not at all
.
At the meet I got to listen to the HD800 and I was very underwhelmed. It wasn't my type of thing. For the sound signature it was going for, I actually preferred both the Q701 and K812.
I got to listen to the LCD-2 as well and while I liked it, I liked the LCD-3 the best. I didn't feel the LCD-3 was worth that premium (at all).
My favorites by far were the Heaudio Jades and the AKG K1000. The Jades were just warm, buttery smooth, and just what you'd think a HD650 upgrade would be. I've never heard such lovely lows (the Denon D7k are another story). It really was a more mature, powerful version of a HD650. The K1000 was just amazing on it's own. It's hard to describe it without hearing it. I was definitely SUPER skeptical of it going into it, and was truly astonished. It was as if it received all of the potential excitement I had for the HD800.
Between the HE-6, HE-500, LCD-2, LCD-3, and LCD-XC, I didn't get those mids that I've come to love with the Senn's, where as the AKGs, Jades, and Stax did a very good job, IMO.
