Dude, stay away from that cable. Either pick up an O2 or move up in the Sennheiser line or stay put. You are not going to get any noticeable improvement from that cable and anyone that tells you that you should spend that much on a cable for the kind of cans/gear you have is not your friend.

Get an O2 or even the newer C5.....money on a $200+ cable is not going to do anything for you....but if u can afford it....buy it and tell

us honestly how much better it is???

Five feet of copper wire for $215 is a needless expense. For that money, you can buy another pair of headphones (or for ~$10 more, something like an AKG Q701.) $215 is enough for an O2 amp and you'll have over $50 left for music, etc.

I do have another Calyx DAC which is also 2v, no issues with this.

Anyone?

Some of you really do not trust in magic cables biggrin.gif? Just thinking of some games that I usually play when I was a kid. Try to use two cans and connect them with a small long cable then two people just hang around, talk and listen to each other. Next try to use a better cable. Magic happens biggrin.gif.

I was doubtful about câble , ordered a custom order at a local shop : mogami 2543 , switchcraft mini xlr connector neutrik 6.35 connector for my gone AKG K702 ,(spl auditor was my amp at time , and A-GD NFB-17.2 as DAC) .

 

first : wow yeah it's different , it's better blablablabla , but wait seams a bit old placebo effect .

 

Plug the stock cable : well that's for sure this is just placebo , custom made cable and stock cable sound exactly the same , why was i expecting something different from a stupid cable , and many many others fantasies vanished :D .

Hey Love,

 

How on earth are you going to connect the $215 magic cable to the tin cans?

 

Send us a pix of that!

 

lol

PS: Thought I read a blind AB test where the string conductor actually won out??

Too much of an audio nub to describe what I'm hearing but it's a fair bit smarter then it was yesterday...

Congratulations on the purchase of the  iFI iUSBpower. I'm glad  that it did put a massive smile on your face.

 

But philosophically tongue_smile.gif speaking (ha, ha, ..) in general  something is wrong with the picture.

- Please don't get me wrong. I'm not  critisizing your purchase. -

 

The price of the device is only $199 .... and the ODAC is under $149 (assembled).

So, the power supply is at least  $50 more expensive than the price of the ODAC itself.

If it were, say  the Benchmark - DAC-1 (~$1600) or DAC2 HGC (~$2K), etc.  this would be  another story.

 

 

I guess,  we're living in the crazy Head-Fi world.

 

 

 

P.S.

By the way, my new JDS Labs ODAC with the included USB cable (with the ferrite bead)

connected via the FiiO cable (from JDS Labs)  to the standalone O2 (also from JDS Labs) sound crystal clear and clean  smile.gif through the Beyerdynamic DT 880 (250 Ohm).

Am I not a Son of a Gun?

 

****************************

EDIT

I am sure that objectively and subjectively speaking the ODAC and/or O2 are not meant to rely on expensive power supplies.

Not sure if stable power is essential or not but in my situation sometimes my father or my brother turns on, turns off the lights, I can hear some strange noise. Look like my laptop does not have clean power. However that happened when I used Fiio E10. Now I have been using ODAC with ferrite usb cable so I still have not heard that noise again but it could happen, who knows. 

 

Hope I will have an interesting experience with power and how it affects sound quality in future when I buy a new DAC/AMP combo tongue.gif.

I guess you don't have odac+o2 combo from JDS?

So if I understand you correctly, on rear side you have:

 

USB In (odac)

3.5 mm Out (odac)

 

and front side:

3.5 mm In (o2)

3.5 mm Out (o2)

 

Or at least this is the only way how I can imagine using only odac part and without AC adapter in odac+o2 combo biggrin.gif

Yes those ports you said are correct. All major parts are from JDS but self assembled.

Do you get the same distortion through the O2 amp output?

Any chance of some macro shots?  The odac should only be putting out around 2V and 339 wouldn't have any issues with that at all.

Swap back to my odac+o2, foobar at max volume, using low gain and it was alright...
Hmm...clueless

Mogami is dead neutral to my ears. You would have heard some minor differences if you had used say an ultra low capacitance wire such as ALO SXC or some random Belden wire.

I used Mogami with my Sennheiser HD-598 because it really doesn't really change how it sounds from stock. Weird right? There are some small improvements however.

 

I also use Mogami with my Q701 because it's as good as stock. Sounds mostly the same. A little warmer, but barely audible. I've tried 3 others and they suck all the warmth out and I don't want that.

 

Also for whatever reason it was stupid easy to hear some changes in cables with my HRT MSII, but less so with the ODAC.

 

I do believe in cables making slight audible improvements, but it's mostly the DIY varieties that I like.

 

I think it all must have to do with the capacitance ratings of cables when built. That was my idea.

 

It reminds me of the differences of well built amps and DACs. They could both be well built, have very low distortion and be really transparent but sound totally different. I mean it's like one can be slightly fuller sounding and the other more cold/analytical. I don't know what causes the changes. To me, cables are like this. Call me stupid if you want.

 

EDIT: BTW getting a cheap custom cable for the K702 that sounds exactly like the stock cable is a GOOD thing. Hopefully you didn't pay over $60 because it could only cost $30 if you did it yourself. Mogami is dirt cheap. Every aftermarket cable for the K702 i've tried is worse. I even tried an ALO SXC cable and it sounds nice at first but just makes it thinner and more analytical. Why? No idea. My guess is that SXC has a super duper low capacitance rating. Sometimes a cable that's technically worse sounds better IMO. For example I like the crappy stock HD-650 cable on my HD-650. Cables never made more than a 5% difference for me.

I'd suspect the 3.5mm out on the odac as a culprit then.  With no distortion using the O2 amp through the odac, and no distortion using the 339 with another dac, that has to be the hangup.

 

Edit: that's why I asked for a macro shot if possible on the odac.  Maybe a bad joint on the 3.5mm out or just a faulty jack.
