First of all, I'd like to thanks Marvey for allowing me to be on the loaner. I just signed up to write down my impressions. I'm glad to be here.

LOL @ Alpha Primes! Where the frickin' body? Why do pianos have no presence or reverb? Jeez it's not even trying to sound like music.  It just sounds funky with acoustic instruments right now. I'm pushing the cups against my head but the coloration is still there. It's not the bass necessarily, it's a midrange thing. How people could pay $1k for this and smile is beyond me. I was enjoying them for a bit till I put on a piano/female vocalist album. Emphasizes the sibilance as well. It definitely sounds a bit peaky on the highs. If not then there is some resonance there for sure. Vocals sound very unnatural on it.

Who do I send to next?
Thanks for the impressions! I wonder if the issues you have with pianos and female voices are a result of the dip in the upper midrange shown in some of the measurements.

Also, it was vaguely unsettling to read "Where's the frickin' body?" in the voice of OJ Simpson. Nice touch!

I'm starting to think whether these need a trip back to Dan. These just sound hella weird half the time. I'm not hearing the praise that's given to this headphone everywhere else...

As far as the tour goes, if Ultrabike has had an opportunity to listen and perhaps take measurements:

- Marv (Socal) *Sent 1/31/2015
- Ultrabike / OJneg (Socal)
- ClemMaster (Socal)
- Original Ken (Central CA)
- RingingEars (Norcal)
- Hans (Colorado)
- TMRaven (Texas)
- Aufmerksam (Wisconsin)
- Azteca X (Ohio)
- Colgin (NY)
- EraserXIV (East Coast)

Should be Clemmaster I think.

Is it known whether Dan has settled on a signature for the Prime or is rolling out revisions? I know he is still trying to figure whether upgrades are viable (or was the last time I heard). I waited a year after the Alpha Dog had been released to get my pair.

Last time I asked, the sound hadn't changed and they won't say if they plan on changing it so...

I'm also curious as to whether there's also a 75% failure rate when making the Alpha Prime proper. Of course I'm not an engineer so I don't really understand these things, but why would there be higher failure rate when upgrading Alpha Dogs to Alpha Primes than there is when making an Alpha Prime outright? I would think the failure rates for whatever he does to the driver would be roughly the same in each case.

The changes are done within the driver it seems for the Primes, so that's why the high failure rate. For the Alpha Dogs (non Prime), nothing is done to the drivers, is just the damping method and new enclosure when jumping from the Mad Dogs.

That what Dan says on his firm's website and on HF but he told a friend that made no change whatsoever to the driver. So either he's lying or he changed his manufacturing process (or both). I think you're probably right either way, gelocks.

Dan says that he pleats the t50rp diaphragm with his alpha primes.  Given that kind of modification, I can see a lot potentially going wrong.

During the earliest trials of the upgrade process, I think Dan said something about soldering/resoldering the T50RP driver multiple times when he removed it for the Prime mods was a minor issue.

I hate it when people are tight-lipped about modifications of their products, and especially when they don't label their products to reflect those mods. E.g., I bought an LCD-2 from Woo Audio months after "Fazor" tech had been rolled out for that model, but my unit didn't have it. It was sold to me at full price without the "Fazor" tech. I didn't realize this until about a month ago.

LOL. You might be lucky. The high grade LCD2s > LCD2 Fazor. If it isn't, complain to Audeze about it sounding veiled (if it does sound veiled or slow); and get a Fazor in return.

That would be great news certainly. I've never had a problem with how they sound; quite the opposite, in fact. I've never really been able to hear in them all the bad stuff people talk about, but have been able (apparently) to hear the good stuff. I complained to Audeze via email a few weeks ago. They ended up calling me and discouraged me from wanting the "Fazor" tech. Apparently, "Fazor" is only for losers with iPhones. But surely a distinguished guy like myself - "you have like, a, WA7 or what? a real powerful amp?" - doesn't have that problem (apparently). That's what the guy said. Of course, I have no objective way of knowing whether I in fact have high grade LCD-2s or am just getting double-blaved by the Audeze guy.
