Hey guys,   My analysis on Primo 8: http://rinchoi.blogspot.com/2014/03/nuforce-primo-8-firstborn.html   Maybe I'll post some subjective impressions too, if I could elaborate the words which I jutted down when I was listening to these few weeks ago. 

I'd like to share my impressions on MA750 with you guys.     First of all, some pics:       (Disclaimer: I've been listening to modded 3DD and my modded MH1 recently)      RHA MA750's sound has a strong emphasis in the bass and the treble; thus it is V-shaped.   Right out of the...

Some pics first:         My subjective impression on 3DD:   As far as custom-driven IEMs go, I've listened to Heir Audio 3.Ai/4Ai, UERM, Hidition NT6, Aurisonics ASG2, and Earsonics SM64. And clearly, 3DD is the best CIEM I've ever experienced: Wide frequency extension, low...

At last, frequency response data of SE846 from myself, in collaboration with SEEKO. Measured with B&K 4157 (IEC 60318-4) occluded ear simulator at the reference plane:     As you can tell, the effect of the extra woofer can be well-observed in the low frequency range. SE846's treble...

Buuump

To all of current DSP-PRO owners here: I need your help.       I've recently acquired Sennheiser Lucas (DSP-PRO) for analysis, but it didn't come with its proprietary Mini-DIN to RCA/power cable. (came with a power adapter though) I can simply DIY the cable, but have no clue what its...

Quote: True. That's why I don't disregard FAD as much as Heir Audio. :P

Quote: No knocking taken. CSD, step, square wave, binaural synthesis, IMD, what not.. you name it, as long as it is not klippel-analysis or FEM, I can pull it off. Might send you a personalized data if you happen to know me personally haha   It's not that I would care if they won't lend...

Quote: I try to keep the communications that I have with companies open as much as possible, unless the manufacturer specifically requests for confidentiality. I don't like secrecy- Nuff of that big-brother-NSA-watching-my-ass. Everybody here should already know well-known reviewers are...

Quote: Thnx a lot LOL

Quote: Wow, whats up with the hostility my friend.. Chill out. First of all, Inks is my friend, not my sidekick, along with Flysweep, James, Gnarlsagan, vwinter, kimvictor, and many other friends. Second, as much as Inks and I agree on certain things, there are disagreements among us as...

There is nothing wrong with their name, I am simply saying it is something I can offer as a reviewer. I don't honestly think hifiman wants the degree of suspicion amplied any further.

Dear hifiman, I requested a demo sample as Rin Choi long time ago but I havnt heard from you ever since. Maybe I can help clear your name if you think the arising doubt of over-pricing among users unjust. ;)

Audeze LCD-2 Rev.2 has been added, along with Sony PFR-V1 and Stax SR-Lambda Pro. Audeze was generous enough to send me a demo pair. Once I borrow HD800/SR009 again from anetode, the only remaining item will be AKG K-1000. Anybody willing to lend me a pair? 

Quote: Because Asr is accusing me of "blatant disregarding someone else's headphones"? I am simply at loss of words here. 

Quote:   Hey, Asr. I feel extremely offended here.. I don't know what's up with your silly accusation. I've had tons of loan previously- SR009, LCD-2, IE800, and what not with users and manufacturers alike, and have never had such issue. (Recently LCD-2 went back to Audeze in a mint...

Quote: That's why 1/24th is also presented along. And we all know pink noise(RTA) tends to introduce interpolating jaggedness to the result. ;)

Quote:   I told them to stop acting like a sissy and deal with me directly already... I don't know why they are playing this funny game of theirs, by responding to you and not to me. Earsonics, are you scared?   Anyway, their data is definitely not of a 2cc setup. It is indeed an IEC...

I contacted them long time ago, my friends, but without a response  If that's what they want, then that's as far as I will go.

Quote:   The data above is most likely derived with a 2cc coupler, which is basically a metal tube with a mic attached at the one end, not to mention that the 2cc coupler doesn't reflect ear canal impedance. It seems there is a low-resolution smoothing applied too. This is the exact same...

NP, my end goal is same as yours: curiosity. The focus is to retrieve as much data as possible from the technology used in designing these headphones, so that they can be looked up for any future reference. For instance, ear speakers have so far proven to be unsuccessful in terms of truly...

An unfortunate event has occured with my simulator. Consequently, general analysis on Sennheiser HD800 & STAX SR-009 data will be disposed, as they need to be analyzed once again. I sincerely apologize anetode(Gennadiy) for all the trouble.

I'd love to acquire a review sample from Shure... 

In terms of SQ, ACS sleeves are horrible. Out of four castings, none of them came close to the resonance properties of stock sleeves. IOW insertion depth was way too shallow. On top of that, bore length on both channels did not match either.

The very first one who answered my call is anetode, who let me keep his HD800 for analysis for a full month. With his support, I was not only able to measure the ring radiator's directivity characteristics within the housing, but also was able to come up with a nice hypothesis in Sennheiser's...
