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...

Two years later, the result is the RDAC. The method used is called sign-magnitude representation. On each channel we have 2 ladders, one dedicated to the positive side of the waveform, the other for the negative side. The purpose of this is to involve a smaller number of changing bits between positive and negative, without introducing too much bias.
Our Partner: Airist Audio Some of you know Airist Audio for their Heron 5 amplifier that has been sold here on Massdrop. The Heron 5 was their first product and a statement that you can make a great-sounding solid state amplifier by paying attention to phase (timing) performance rather than just frequency response (bass-to-treble linearity). They had a different angle to amplification and a clear goal which they achieved. Descriptions of the Heron 5 are never “sterile” or harsh, but warm, natural, and “involving”. The design and execution of the Heron 5 led us to ask Airist about taking on our challenge of making an entry-priced R-2R DAC with the sound and performance of much higher-cost units.They understood what we hoped to offer, had clear ideas about how to approach the design, and believe in what Massdrop is trying to do. (FYI: One of the reasons Airist Audio hasn’t yet followed up the Heron 5 with another product is because part of the team was working on tackling global health issues…turns out that similar technology is helpful in solving audio-related problems as well as tackling disease in populations. Another reason is that they were working on this challenge.)
Community Feedback/Community Validation Great gear makes your music sound the best you have ever heard it. Or, great gear just gets out of the way and you forget about the gear and just listen to the music. We’ve gotten several RDAC units out to community members to be sure it sounds good. We’ll get some review links up and ask them to post here. Some early prototypes were circulating as far back as 2016. In that period of time, we have changed the inputs, the input selection switch, parts used on the PCBs, the form factor of the entire thing (to stack and look good with our amps), along with the power supply voltage & regulation.
Technical Chat William Tse of Airist Audio will have limited availability due to his current projects but will try to be online to answer questions here in discussion for a few days. We will then collect questions throughout the drop and relay the top questions to him in an additional First Purchaser Q&A after the drop ends.
While you can't change the Sigma Delta DACs that are already in your phone and all the various equipment all around you, now you have a choice that you can make for your audio system that won't cost you thousands of dollars.
This is an important launch for us, a high-level affordable separate DAC of great sound quality in a matching chassis to accompany our recent amplifier launches.
We’re excited for pics of your stack and to read if people stay up "way too late” listening to their rigs. :)
- With the Lighting to USB 3 adapter you do not get the power message, but the RDAC is not recognized at all. This is true with, or without, power applied to the adapter.
- With a powered hub, known to work with some other DACs in this configuration, the RDAC is not recognized at all.
In this case "is not recognized" means it does not show up, at all, as a selectable sound output deviceAdding an adapter on top of the power plug is going to add a chance of power cuts which might causedamage to my investment.
I think this should be throughly reviewed if massdrop is going to sell to international customers.
I am from Australia so US type plug is going to be trouble.
