Well...a little more than a year ago, I measured all the JH custom line with the demo units HeadRoom has. I noticed a lot of shifts in phase, mostly in the cross-over region. I notice this on most multi-driver IEMs to some degree, but I also have to say that some that I very much like (JH13, Shure 535) have it a lot. It's common in speakers that have higher then first order cross-overs. JA has a good article on time coherent speakers vs. ones with phase shift. But he also says that he can't find any correlation between reviewers liking or disliking speakers of these types.
Anyway, I decided not to publish the JH custom measurements 'cuz I didn't understand them, and I didn't to raise a lot of unanswerable questions about Jerry's product. And they sound good.
So...at the show Jerry comes up to me and says, " Tyll, I had a complete rethink. Everything I thought was wrong. I've completely time aligned my drivers to within 100uSec." I don't think he remembers me talking to him about the phase stuff, but it might have been one of the seeds. It matters not ....
The Freqphase JH13 sounded even moar betterer than the standard ones...clearly. sounded. better.
Some of the lushy gooieness of the regular one is gone, but it's replace with sublime transparency.
I'm working on a collaborative custom in-ear review with the some of the InnerFidelity writer team. Between us we have a lot of customs, but we need a common reference. Jerry has agreed to do the new Freq JH13 for four of us.
On other fronts: I'm back. The bike was packed and I was rolling out of the Hyatt parking lot at 4AM. Arrived home at 5:55PM 703 miles later in Bozeman. Great ride, windy as fuck but my FJR just cuts though it, gray skys all day made it less fatiguining on the eyes, rode in drizzle for about a half hour, perfect.
Best shot of the day:
