I own an HD800 with Valhalla 2, and I'm getting the LCD2C as my complimentary pair (I kept some LCD2s for a month and then sold them in anticipation of the C release). For the forseeable future, this is my endgame. I'd like to try Stax, but it'll be way over my budget for a long time. I'd love to return the LCD2s and grab the 3s, but $600 is about the limit of what I feel comfortable putting in something that I know will eventually die. If Audeze's handling of driver death were more reliable I might even sell the HD800s to get them, but alas. As things stand, unless or until I get to hear a real high-end amp with the HD800s this is my setup. So I do not need and probably don't want my LCD2s to sound neutral. That's why I went with the Cs instead of getting the $700 deal on 2Fs. So I'll use the HD800s mainly for female vocals, acoustic stuff like City & Colour, stuff like The Mars Volta, CHON, Polyphia with lots of treble energy, and anything wide and airy ... and the LCD2's for stuff with heavy 'wall of sound' guitar effects and lots of bass impact. Nine Inch Nails, Swans, Tool, Mastodon ... stuff where raising the treble would also prevent me from blasting it as loud as I want to. That said, what's the best amp I can get to power the LCD2s that ... 1. Is preferably under $500, the cheaper and better performance per dollar the better; 2. Focuses on improving the LCD2s in the areas where they already outperform the HD800s, rather than balancing them by complementing their weaknesses (liquidify the mids, improve bass slam and texture, who even cares about treble); and as a bonus 3., would also pair decently with the HD800s as a second option for them?
