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...

I'm very intrigued by this DAC. However, I have both the ODAC Rev B/O2 amp combo, and a straight up O2 amp, both from previou drops here on Massdrop.
To be perfectly honest, I'm not a fan of how they sound. While the numbers and measurements are good, and it is a competent performer, I find it sounds somewhat clinical and mechanical. I find it lacks a sense of soul.
That's my personal feeling on the performance. Others do find satisfaction from the ODAC and O2, so it's not for me, that's all.
I'm curious if this amp is essentially a remake of the ODAC design. Important to know, because I would personally rather not purchase one if the sonic performance is similar to the ODAC.
Any reviews we can reference to get an idea of the personality of this DAC? That would be most helpful.
Thanks.
ODAC and SDAC are both budget DACs, and 79.99$ is not a big amount at risk here to try it out. Some early reviewers says it sounds better than the Modi and the ODAC. I guess we will only know when it is released to the consumers that have ordered it on this drop. I also matches the looks of the O2 that I bought a few weeks ago from Massdrop. Enough said to take a 79.99$ chance on this item...
While I definitely agree with you about changing the overall system sound via amp and headphone choice, I respectfully disagree with thought that all decent DACs sound the same (you had specifically mentioned tonal balance, but I believe that's the gist of what you said).
In my experience, I have noticed clear differences in musical presentation among DACs. Among those I have used are the ODAC, Modi, Teac UD501 and UD503, Denon DA-300 USB, Grace mXX, SMSL M8, amongst others. I do hear differences in presentation. This is all in the context of the same supporting system.
I don't know if there's any difference in frequency response. The differences lie more in things like sense of space in the soundscape and around instruments, the naturalness of the textures of the instrumental and vocal sounds, the naturalness, speed, and depth of note decay, the complexity and richness of the harmonics, the musical flow and sense of rhythm in the song or piece, etc. Things like that.
I don't know too much about the technology of digital playback. I just plug in the DAC, maybe play around with the filters and settings, and listen to music.
I found, particularly, that the ODAC did not bring me the enjoyment that I found in some of the other DACs I own.
On my computer, I had a hard time discerning the difference between the Modi and an original Audioquest Dragonfly, so I won't say I hear a difference all the time. But most of the time the differences led me to prefer one DAC over another for long term listening.
That's my experience, anyway.
I did not enumerate the other different components used by each DAC, like the Op Amps, which are probably all different in each aforementioned DAC model. In the case of the SDAC, the op amp is a Burr Brown OPA1652.
In other words, all of these DACs are different, using different components. So your dislike the ODAC (Original or revisionB, I don't know which you tried) that doesn't mean that you will dislike the SDAC in the same way. For 79.99$, you should give it a try. That is what I'm doing, I have ordered the standalone SDAC.
By the way, the original Dragonfly uses the same DAC as the original ODAC, the ESS ES9023 24 bit Sabre DAC with Delta Sigma architecture and Texas Instruments USB controller TAS1020B. Current Dragonflys use the ESS ES9010 32 bit DAC (Dragonfly Black) and ESS ES9016 32 bit DAC/AMP chip (Dragonfly Red) with USB controller Microchip PIC32MX. All different configurations...
Live and learn, I guess.
