Sennheiser PC37X randomly goes bad after disconnecting the cable ?
Greetings, Yesterday I was using my headset like normal with my macbook, just listening to music and on a call with people like usual, and the headset was perfectly fine. The stock wire that came with the headset is extremely long and yesterday it annoyed me very much that it kept getting tangled with itself, so I decided to see if the cable is replaceable. I pulled out the cable from the headset and saw the adapter, and looked online for a replacement. Upon plugging it back in, the audio sounded extremely muffled and washed out. Im not sure what I did wrong to make it mess up like that as I've always taken good care of it, ive had it for about 2 years and its always just been chilling on my desk, but anywho I thought the cable just went bad and ordered a replacement. The replacement came, and the issue is still persistant, so I am not sure what the issue is I've tried multiple different headsets and the issue is not with the port, and I also tried it with my windows laptop and...

There are other layouts that can be used, for example here is what Augio-GD's looks like: http://audio-gd.com/R2R/R2R2/R2R25.jpg
So it seems very strange that this is using the exact design layout from someone else. Please address in technical detail how these two products are not the same design, and how it is that this was designed and why it looks the same as that other guys product. Just changing what resistors are used is not enough to make it a newly designed product. Who is this supposed consulting engineer who is supposed to have designed the product? Why didnt WilliamTse design it himself? How do you know that whoever you paid for the design didnt just take that other design and say "here you go!". IF this really was newly designed, it wouldnt share the same exact layout as that Hibiki one.
We are working on a balanced version of the SDAC, but the release timeline is unclear.
And if indeed copyright law doesn't cover the trace layout on a PCB which you are in the clear and that's why you launch? That makes MD a very shady business.
I sure hope sosolar can find legal council and take you guys to court if indeed someone stole the design.
Common sense tells us that it's impossible to sort out such complicated IP issue in under 24 hours. Fact is MD did not even contact sosolar to investigate as far as I can tell. So how could MD nor anyone claim this is not stolen? And did MD nor Airist proved indisputable prove that this is their won design? Can they show the prove of their development cycle? NO! But instead every explanation they gave so far makes me think otherwise. Yet, amidst all these accusation MD decided to launch before they clear any doubt.
But hey you are a grown man and can make your own judgement, educated or not.
This statement was posted 15 hours ago and you've invited sosolar to email you and discuss the matter only 2 hours ago? Just curious, how can you make such a claim before you've talked to sosolar?
As a company whose long term success depends on our ability to bring communities and companies together, no individual product matters more than our ability to create these partnerships/collaborations. This is different from most companies that produce enthusiast products, where the success of an individual product launch often makes the difference between paying rent or going bankrupt. I'm explaining this so you can understand the underlying incentives at play, and to help folks understand why there's a theme in many communities of companies doing shady things. So baseline, for us, there is no product that's worth being shady over, we're not worried about paying rent, we’re focused on getting more people into this community. Next, a big goal for us in these collaborations is to encourage more community members to create. As such, we go to great lengths to protect and reward those creators. We are approached by dozens of groups every week selling knocked off designs which have no potential for legal backlash and we turn them down. Instead, we work with, and compensate, the designer. We’ve paid out nearly $250,000 in royalties to Massdrop community designers over the last few months. I'm sure sosolar is a great person, and he/she is probably enjoying a spike in board sales given the thousands of American community members who learned about Hibiki through this discussion, but if the RDAC is a copy of this project, where’s the second board? Why is the part spacing different? Where is the chassis? Why is the power supply different? Etc, these points have all already been covered by Airist. If you want to say “I don't like that Airist's team was inspired to use a similar layout for the top half of the RDAC pcb", that's fine, but if you're going to call it a copy or stolen, that's unfair to Airist, Christian, and the rest of our team who spent hundreds of hours making this drop possible. If the RDAC was related to another project, it would have come out in the development process. To summarize, it's not worth it for us from a financial or branding point of view to support a copy, and it's fundamentally counter to our goals of supporting the development of more community designers. It’s been entertaining to watch this unfold, maybe we should add a popcorn button next to our endorsement button, but William provided the technical information, and I’ve provided the Massdrop priorities explanation, draw your conclusions. Thanks for being part of our community!
No you should add a thumbs down button instead so that we can see how these posts with dishonesty and lies will be disliked to death.
You talked to William from Airist but never talked to Sosolar, and yet you came to the conclusion that William and his team did not copy the Hibiki PCB?
After reading your disingenuous reply I've made up my mind once I received my last transaction from MD I'll cancel my account and never ever do business with again. Or better yet if you can cancel them now and give me the refund I'll get out of this shit hole immediately.
Thank you and good luck in practicing your questionable business model!
Thank you for the HD6xx!
Sure I will.
The R-2R mechanism can be used in a variety of different ways. The RDAC uses a fundamental form of R-2R, a straightforward 24-bit sign-magnitude converter. More complex designs, such as the Ring DAC, apply different control logic to account for issues with tolerance and distortion that R-2R DACs can have. These are elegant solutions that sound great and are a different approach to R-2R than the RDAC, which focuses on simplicity.
At $350 I want quality, not want you speak to. There are too many excellent products out there already at this price with a track record, positive reviews from publications, and multiple comments and exchanges from MULTIPLE individuals commenting on the product that seems to indicate it is good product.
You need to release a product that has a rock solid design if you are not going to attack at price.
Or you can mislead the poor folks on MD into buying these products.
1. No MQA capability with this DAC? But used with Roon I can still get the first MQA unfold?
2. One review shared with the drop says: Factor in the ability to upgrade it to an almost shockingly high level of performance, and you can see why it earns a very strong recommendation.” – John Grandberg on Head-Fi
What upgrade? How does one obtain it? What is the cost? Or does it not apply to the Massdrop version?
Thanks!
I think you captured the situation really well, and it seems like the post I just made on Head-Fi would be of interest to you. https://www.head-fi.org/threads/massdrop-x-airist-audio-r-2r-dac-a-discrete-resistor-ladder-dac-for-350.881315/page-12#post-14294445
Take a look and let me know what you think. Would the discussion here benefit from me posting the full text?
I'll say it again. It's the actions and manner in how you and MD handling this so far that makes me lost confident.
Fact of the matter is they took time to figure out what was going on (considering the language barrier) and try to parse the situation before responding. That's reasonable. And, they're still going through all the right steps to get answers for themselves and the community. Which is reasonable.
Honestly, until more information comes out, we're all just speculating and gossiping since we really don't know what's going on anyway.
Here's my head-fi post: Thank you for taking time out on the weekend to reply. However, this might be a little too late for some.
As I said before I'm disappointed at the actions taken by you and MD. I would have totally bought this explanation if MD would have postponed the launch to do the investigation first. But instead, MD callously decided to launch. And put out a statement claiming the top board has nothing to do with Hibiki design before making any contact with sosolar? Also, your arrogance in hinting that this dispute might actually be benefited sosolar because it brings attention to the Hibiki? And just now you still try to play lost in translation and mocking sosolar's English? You could have had your Chinese speaking staff write him the message! Simple as that! (Will took time and effort to PM me and addressed the situation in regards to the language barrier and I'm satisfied)
I'm not buying your explanation at this point because it sound more like damage control.
But hey, mistake happens. You still have the chance to make it right. As suggested by others you can collaborate with sosolar to develop the balanced version providing that he is as good as he claims. I'll say that's a happy ending!
I shall make a preamble and say that, after all the posts about the similarities between the RDAC and the Hibiki DAC, I do really have confidence in what Massdrop has explained and I trust the Hibiki could have been just a source of inspiration, which gave the RDAC project an additional term of reference among the many available on the market. That’s what it looks like to me at least!
So back to the RDAC drop: what about the XLR inputs available on the LCX? Why should anybody want to connect a DAC to his/her Liquid Carbon X by RCA connectors? In my case, why should I dump my high quality XLR cables (Audioquest Mackenzie River), buy new RCA cables and ditch the balanced design on my LCX? What was the reason for Massdrop not to offer a balanced DAC with both XLR outputs and single-ended RCA‘s that could pair well with all the Massdrop-Cavalli amps? Not to mentioned that quite a few members here have purchased both a CTH and LCX. Should they also buy two DAC’s, if a balanced DAC will ever be offered by Massdrop?
Some how I feel we are about the same age. I believe the upgrade that John is referring to is the power source he used his linear power supply rather than the switching power supply that comes with the unit. And for MQA files I doubt that this DAC would have that capability but I could be wrong, I think they would state that in the Specs. Just reading the article below it seems to be specialized hardware for that. Though it is interesting Dragonfly DACS are capable. You could still use the Tidal desktop app. What streamer are you using for Roon?
https://www.whathifi.com/advice/mqa-audio-what-it-how-can-you-get-it
Reading John's review he has some interesting comments on how RDAC converts audio files with ROON. He doesn't mention MQA but rather how the DAC converts DSD files to PCM.
I'm sure you're right about MQA but I don't know why it is so hard to get Will -- or someone -- to confirm. At one time the lack of MQA support would have been a bigger deal to me. Now that one can get the first unfold via Roon (or Tidal with the Mac desktop app) it's a lesser issue.
My Roon setup uses my iMac as the Roon core and a microRendu as the streamer in the room with my main two-channel stereo.
May I ask your thoughts on this DAC offer? I've read about the technology this DAC uses. I certainly don't "need" another DAC as I have three. But the price is right to try the different approach to processing the digital to analog conversion.
BTW my current DACs are Bel Canto 2.5, Geek Pulse and Meridian Explorer 2.
1. The RDAC is not MQA certified, I haven't tested it with any MQA services.
2. The upgrade being discussed is a linear power supply. The included power supply is not a linear power supply for cost reasons, but if you want to spend another ~$50 (I've seen posts claiming $5 on ebay to $100+ for "special" parts so it seems like you can spend whatever you want on this) all reviewers that tried it reported an improvement with a linear PSU.
Why? Because this would be another selling point for the RDAC, that one can use it to enjoy MQA (those who care to -- I know MQA is controversial and I am NOT trying to get into that controversy).
I am fairly certain the RDAC could be used in conjunction with Roon's MQA implementation but would like to be 100% sure before I plunk down the money for the drop.
I'm just not as familiar as others are with the ins and outs of this kind of a discussion page. Oh well...
If you or someone else can pass my suggestion on to a reviewer, great. If not, I understand.
BTW do you have an opinion to share on the Airist product? As I've said above, I have three DACs so hardly need another. But the different technology on this one -- and the chance to try that technology at a reasonable price which seems unusual -- is tempting.
Thanks!
Thanks
