So, did I break something in the RCA connector inside the DAC? Or are the RCA connectors designed to make that click noise while you unplug/plug the cables? 

 

I'm afraid I might have broken something in the connector, and thereby affect the sound quality. Anyone with any experience/knowledge in this area? 

 

Was it on when you did that? It may have just been the DAC's clock disengaging, or something like that. I'm not sure that's the right terminology but my Bifrost clicks sometimes. I read on the Schiit website that it's the clocks switching.

That is my set-up with a Matrix Mini-i Dac to afford balanced use. I have a friend with a few fairly hi-end tube amps (Darkvoice 337, LD MKVI+ (balanced) etc.). The LD MKVII (with matching LD I DAC) is his "go to" set-up when not using tube amps (which has become most of the time recently).

 

We both love the sound with our HD650s with this amp. I think you'd be impressed if using balanced cans. You can always use it unbalanced while you build your system but the SQ is greatly improved when using the MK VII+ in balanced mode as that is it's primary design implementation.

  I think this guy http://www.ebay.com/itm/261171681247 will make it with a 4 pin for no extra cost. I haven't heard it but I believe he uses Mogami wire, (stripped, braided and re-sleeved). I have one I could sell you but it's microphonic. As long as you don't rub it while listening at low volume it sounds fine. I used it for months while I saved for a silver re-cable.

I don't know... The click wasn't inside the DAC when it happened, but it was more like where the actual RCA connection is. It seems like there are some (metal? leafy?) parts in the connector part, that might touch the RCA male plug. Anyone know about this?

hd650 pretending to be hd800.....angled drivers tongue_smile.gif

post #11736 of 19554

Did you actually tried this ? blink.gif

post #11737 of 19554
Yup...the soundstage moved slightly forward, go try it out.tongue.gif
The foam is from an aircon doorstrip.

Lately I've been wondering why no one has ever made angled pads for the HD6x0. If you hold the drivers at an angle you can get an idea of how it sounds. Seems like there's a lot of potential there to make the soundstage wider and more realistic sounding and to improve positioning.

post #11739 of 19554

Interesting...just tried the angle to see for myself. It does make a difference. And I think that the sound stage does seem wider.

So... how much volume does it take to destroy a pair of HD-650's? I accidentally plugged it into the headphone out of my motherboard onboard audio (to compare with my standalone DAC) without checking the audio levels, and it ended up blasting away. The volume level was certainly enough to damage my hearing (if I were to listen to it at the volume for a long period of time)...

If it was briefly I doubt it'll hurt your HD 650s.  You'd likely sooner hurt your ears first.  Sound pressure level of the cans is rated at 103 dB according to Sennheiser... so it's roughly the around the range of a lawn mower or snowmobile I believe?

post #11742 of 19554

I found my best portable setup last yaer....

both of the cables were made by an audiophile friend of mine... 

the cable for the 650 is PcWork Symphonica 

while mini to mini (the blue one) is Legato-S

and amazed with GoVibe Vestamp...

 

I can fit everything in a casing and carry wherever i go :D

The 650's are likely ok. If you have a blown driver you be able to hear it. Your hearing is a different matter. Did you have them on when you blasted them? I got a blast from a set of IEM's about three months ago with a dap on maximum volume. My hearing has still not recovered. redface.gif

joe: Ah. Thanks for letting me know. The reference to the landmower/snowmobile is especially helpful. I actually googled it to double check, and it seems you are right: http://www.gcaudio.com/resources/howtos/loudness.html, with the snowmobile/motorcycle at 100db, while a powermower is at 107db. And, the Sennheiser website lists the HD-650 SPL, at 102db, indeed as well. Thanks again for letting me know. And thank God my HD-650's are ok. Now I REALLY know they're ok. 

 

matt: Ouch. Hope your hearing is alright. I did have them on for a second, and while I do notice a tiny, tiny bit of ringing in my ears, I'm not sure if that was because of the incident, or if it's a case of tinnitus that I've always had. 

 

coolerthings: That's a sweet set-up man! Everything there looks sweet: the headphones, the cables, and the amp.

Just reading about headphones blasting your ears at max volume, even for a split second, is making my ears hurt... ouch.
