Hi All,
 
As you may have seen, RHA has just launched two new in ears and we’d like to run a sample programme for both MA750 and MA600.
 
In order to reflect the community-minded nature of Head-fi, we’d like to distribute samples in pairs. If you would like to receive a sample set to review, we ask that you also nominate a fellow Head-fi’er to receive a sample. Ideally those who you nominate will be forum users whose sonic preferences are in line with the sound signatures of our new products and have experience testing similar products.  We’ll be selecting 4 pairs of Head-fi’ers, which means we’ll be sending out 8 sets of headphones in total.
 
Onto the sound signatures!
 
MA750: We designed the MA750s with handmade 560.1 drivers for precise, balanced and articulate sound reproduction with a great depth of soundstage.
 
BigAund agreed, posting that he finds them “good all rounders with nice bass, good detail and a pretty large soundstage.” ClieOS also enjoyed the MA750, saying that “ have to say I am quite impressed.”
 
Udauda measured them and commented that “With the help of RHA's proprietary Aerophonic™ Design & the hand-crafted driver, its treble extends all the way up to 20 kHz, and secures miniscule details that can easily be overlooked with most of conventional IEMs. As such feat is extremely critical for reproducing the sound of instruments with rich harmonic components, such as a violin and a clarinet, MA750 finds its glory when an accurate treble is essential.”
 
We’re offering 4 sample sets of our MA750s in total; nominate a Head-fi’er who you know prefers an open soundstage and detailed sound and both yourself and your nominee will receive a sample set of the MA750 for review.
 
MA600: We built the MA600s with our customer 320.1 drivers for precise and balanced sound reproduction.
 
Warrenpchi tried out the MA600 and thought that ‘If you're straddling that line between basshead and traditional audiophilia, this should be near the top of your audition list.’ He went on to say ‘Overall, the signature leans warm and is very bassy in the low end and lower mids... transitioning into a unexpectedly smooth and refined mid-range and upper-mid-range.  Highs are largely without fault, though lacking in the sparkly airyness that trebleheads favor.’
 
The same nomination system as for the MA750s will be used to distribute MA600 samples- nominate a Head-fi’er who you know likes a refined sound but with a little more bass, and both yourself and your nominee will receive sample set of the MA600s to review.
 
Nominations will be open for one week; followed by our selection process where we’ll determine the pairs of Head-fi’ers to receive sample sets of the MA750 and MA600.
 
We'll be closing nominations in 1 week.
 
Thanks,
RHA Team

Thanks RHA team for the generous offer!!!
 
I would like to have a go at it with your MA750s and would like to nominate fellow head-fier TwinQY as my review mate. We both have pretty interesting reputations/ contributions here at head-fi (I would like to think it's of a positive one
ksc75smile.gif
) and we seem to work great as a tag team. TwinQY have had A LOT of experience with IEMs as well as full size headphones it seems so he is pretty anal regarding his sound, therefore the more sophisticated/ refined sound of the MA750 would be more of his ideal signature. I on the other hand is relatively a novice to all this audio madness, but is trying to learn quick. Initially I preferred a more "bass" centric sound, but my experiences with budget-fi gears has made me realize that a more balanced sound is much more engaging/ versatile for the long haul.
 
I have actually written a review of the RHA MA-350 that I won as a prize from Dsnuts' contest and was really impressed with their overall sound especially if you take their low cost into consideration.

Here are some of my other random but more concise reviews of IEMs that I had on loan which made me realized that I have too many bass centric gears in my collection and that so much bass can get a bit monotonous. haha

But if you are interested in my more creative yet "concise" cough***NOT**cough pieces that head-fier TwinQY helped me A LOT with in edits, etc (This is why I say we make a great tag team amongst other things....) here you go. :)

Hope I didn't come off as too desperate but it is what it is. : P
 
Again thanks RHA team for this opportunity!!!

I wasn't online at all the past few days, so this is unprecedented to say the least. I'm quite touched by sf's gesture. Hopefully I don't ruin this thread with my sappiness.
 
I'd definitely be interested in tag-teaming with him.

I would love to take a shot at reviewing the 600's as I prefer a slightly warmer signature. I would nominate fellow Head-Fi'er Kazsud as another reviewer.

Interested in the 750 model, as i already own the 350 one (review soon).
I would like to participate together with Head-fi’er Jant71
 
Thank you!
 
Note: i'll write the review not only in English, but also in Spanish

ClieOS reviews oodles of IEMs, and would be a great person to review the MA750!
 
Also, if you would like to send me some to audition, I'm looking for a replacement for my Shure SE215, and it's either the MA750 or the Hifiman RE400

 would be driving it mostly out of my phone, but also my Sansa Clip Zip, and HRT Microstreamer.

I'm also interested in the MA750. I would say my preferred signature is a balanced one. You can check my profile to see some of the IEMs I've previously owned.
 
I would like to nominate Head-Fi member mechgamer123 as a fellow reviewer. I'm not entirely sure of his preference for soundstage, but he generally enjoys a balanced and detailed sound.

First, I'd like to thank the RHA Team for doing this.
 
I am very interested in reviewing the MA750 because I am a bit of a detail freak, love tight, fast but impactful bass and a nice crisp, non-rolled off treble. I've never tried a RHA IEM, but I'd love to get the chance. Here are a few of my reviews:
 
Unique Melody Miracle: http://www.head-fi.org/products/unique-melody-miracle/reviews/9156
Rhapsodio RDB v1: http://www.head-fi.org/products/rhapsodio-rdb-hybrid-2ba-dynamic-driver/reviews/9266
Astrotec AX7: http://www.head-fi.org/products/astrotec-ax7/reviews/9646
 
 
For the MA600, I would recommend H20Fidelity. He seems to enjoy all sorts of IEMs and I am sure that he would give it a nice, honest review. 
 
Thanks guys.

Thank you guys!
 
This would be my first RHA IEM, but not my first review. I would love to give a fair and detailed impression of the 750. If I love them that much, I will end up owning a pair
 
I would nominate Teska, as we have been testing chinese brands to find hidden gems little known outside of China, and we have similar signature tastes.

As lin0003 has nominated me I will make a post and express further interest, I am quite flexible to different sound signatures. Some of my reviews can be seen linked below.

I would like to nominate a Canadian, waynes world. He has done a phenomenal job finding budget and bang-for-the-buck earphones and getting many head-fiers to try them. He's a young man on a limited budget, but he has never hesitated in sharing his findings. One time, he found some good sounding budget earphones that were only available in Canada. He offered to into his own pocket to send me (and others) a pair to Chicago just so I could hear what he was hearing. 
 
I've been purchasing more so-called top-tier headphones and earphones, but the suggestions by waynes world, Dsnuts, and DannyBai in the Discoveries thread opened me up to believing that near top tier sound could be found in some of the bang-for-the-buck in-ear monitors. Thus I found my way to the MA750i (which I have written a good bit about in the discovery thread in the portable earphones & and headphones section). Sure, there are a few head-fiers who get samples reviews all the time. They seek it out. Yet, it would be nice to see some head-fiers who don't get sample reviews often, but they are just as capable in describing the nuances of the sound in various products. 
 
I personally wouldn't mind hearing the MA600, but even if that's not possible, I still would like waynes world to get a review set of the MA750i. Knowing his sound signature preferences somewhat, I know he'll appreciate that earphone and write some great impressions on it. Thank you.

Eric, thank you for the nomination! 
 
It would be my honour to review either the MA600 or the MA750. Based on what I have read, they are both are very intriguing to me. Both have qualities that I appreciate, such as the deeper soundstage of the M750's, and the enhanced bass of the MA600's, so I honestly would be happy reviewing either of them.
 
I don't have any official reviews under my belt, but it would be great to start with either of these RHA offerings.
 
Thanks again ericp10, and thanks to the RHA team for offering this review program!

I'd like to nominate Tomscy2000.  His posts are always interesting and informative; it's obvious he has a consuming passion for portable audio.  Over time I feel I've learned a lot from his Head Fi input.
