Crack - specific headphone kit?

I will be listening to the new cable design later today. Cross your fingers.
 
No interest at all.

Bought a new set of HD600's for $350.  I'm done.

Never had a headphone rig, thought I'd try one out.  The sound is amazing.

The other reason I bought it is as a reference.  From all I've read Crack/Speedball/HD600 is as neutral as it gets.  So that makes for a good reference.  I really hate headphones.  I want to listen to music that sounds that good w/o the clamp on my head.  IE speakers.  The headphone rig helped me with the speaker design - :)
 
I'm not sure of the relevance of the last five posts to the subject matter of this thread. I'm pretty happy with the end result today. The headphones sound quite different than stock - more extension on both ends and much more punch. In fact these are some of the most punchy headphones I have heard. That quick transient attack is really pretty neat. We're gonna work out a few final details and then I think we will release what we have come up with.
 
Very interested to see what you come up with, and if they have the same synergy as the HD600/Crack everybody raves about i'm sure they will be a great success.

I doubt they will interest me personally though, especially if they are anything like the Sennheisers. I have the 650's and just don't like them, i've tried time and time, respect them, just cant love them.
 
These really aren't anything like Sennheisers in terms of construction so I don't know that experience with that sound will help much to describe these cans. I just tried them vs. some  ATH-AD900s that I like a lot and found that I prefer the quicker, punchier sound of the new cans. The ATHs easily win on comfort though. Those who want a really tubey, big tone midrange kind of sound may not like these new cans that much. These are more of an extended frequency sound without much mid bloom. Clean highs, more of a neutral (maybe less intimate is a reasonable descriptor?) mid sound, and very dynamic bass that actually lets your ears feel some impact. Not like gut pounding bass, but there is a definite tactile element that I found a nice surprise. Vocals sound balanced and resolved, but they don't do "big head" or "chick whispering in your ear". Maybe the best description is that the cans seem to bring out those OTL amp positive attributes of tight bass and a very clean sort of sound.

One thing for sure, I could REALLY hear the improvement that John Swenson's software filter makes over the DAC chip's stock filter.  Turned out I had been running the stock filter all day during a listening session on Friday - arggh.
 
OK we crunched some numbers today and the project looks viable. We need a few more parts to build a production prototype and I want to try a couple of refinements to the damping materials I chose. Here's a little teaser of the prototype kit cable.

Very nice, can i ask what cable you are using or is that a trade secret?

My condolences to whoever has to solder those 3.5mm sockets, i smell lots of burnt fingertips in your future :)

I'm guessing that the headphone Doc has chosen already has a 3.5mm socket - I doubt that the kit will involve drilling for and then wiring up a socket, though I might well be wrong.  We'll know soon enough.  Soldering a 3.5 plug is not at all difficult, even for my past-their-prime eyes and fingers.  I am curious about the cabling, though.  I've done a whole bunch of custom headphone cables and am curious to see Doc's approach to enhancing the high end.

I'm most definitely in for a pre-order when they become available.
 
Guys, remember that I am a pragmatist. The cable was chosen based upon my previous experiences with what works to open up the top end. There is no magic 11 strand overhand braiding for transparency sublimation or boson enhanced silver flakes for reduced time dilation or imperial yak hair lining for lower uncertainty factor. It's just high quality commercially available cable that got the cans to sound the way I wanted for this particular application.
 
Most assuredly. 

Especially if you had the H1N1 flu virus.  Which is so strong it recrystallizes the copper molecule to a more transparent phase.
 
Hi Doc and all.
Don't count me in (For now) but I am curious to see what you will come up with.

No speculation involved here, just a curiosity as to what you will be using.  Certainly, at the price point mentioned before, no one would expect esoteric materials and being a DIY kit, we'd hardly expect you to have people braiding 4 wire litz configurations. I'm happy to just sit back and wait for you to announce availability at some point.
 
Hi Doc,

Really interested in purchasing the pre-order but the international shipping really kills the deal. Is there any possibility to have some kind of economic shipping to Australia to sweeten the deal?
 
maybe a dumb question... is there resistance in the cable to increase the load impedance as seen by the Crack, so it operates in it's butterzone?
