That would be a sweet system for use on the road. The size would make it impractical for me, sadly. I only take carry-on, and have the misfortune to often route through London Heathrow, where they take a perverse and palpable delight in confiscating regular US-sized carryons; the Heathrow limits are a few inches less than, um, those in the civilized world. Even with US-sized carryons, the HD800s would be too big to cart around. A pity.
The Woo WES, and the Wyred4Sound DAC-2, and the Stax SR-007s, are all new. So I'm early in the break-in for all of them. I've noticed, not surprisingly, that they demand high-quality source material. For the most part, I've been really enjoying the sound, but have not yet been blown away by it. Then I listened last night to a Chesky sampler disk. OMG. The sound absolutely blew my socks off. I think it's partly because the recordings are so good, partly because I'm getting used to the new setup, and partly because the most dramatic improvements in break-in take place in the early stages. With about 20 hours on the system, it's beginning to really impress me. Absolutely magical and thrilling, and truly joyful. I'm so glad I took the plunge. I took the easy way, and I know it: instead of slowly upgrading, I dove into the world of high-end headphone audio starting at the top (if you don't count my Hifiman EF2A and HD650s). I didn't pay my dues, or experience the long learning curve, and so I'm not appreciating this as much as someone who did it the slower way. But I'm still grateful and appreciating it a lot.
