Circlotron's are optimized to accept a balanced input signal.
Like Super Symmetrical topologies, they can take SE inputs.
But they operate better from balanced inputs.

I think someone may have asked me in this thread about the HDMI i2s card for the AGD M7. Here is the link to the info: http://www.head-fi.org/t/625793/audio-gd-master-7-discrete-fully-balanced-dac-pcm1704/1560#post_10394607

I recently got PWD2 and it is very good upgrade from bifrost. I was wondering if USB cable that keeps power and ground completely separated like this one 

 

http://home.comcast.net/~ridgestreetaudio/Poiema_USB_40_Ad.html or iUSB with dual-path Gemini USB cable, makes any difference ?

 

apologies if this question is already asked and discussed.

You can try cutting the USB +5V or putting tape over one of the pins of the USB adapter. I think this should work with the PWD2's XMOS and yield similar results. Might want to ask in the PWD2 thread or search around on how to do this.

 

I simply cut the +5V on the USB of a Belken Gold cable for use with the OR5.

Ah, the Belkin Gold!

I guess you don't use boutique USB cables?

No judgement either way, I'm just asking.   :o

Thanks a lot, this helps and saves $. I will search around, also if you can post pic of your Belken Gold cable, it would help me to implement same.

I think it needs +5 to "handshake". just get a powered usb hub and then get a regulated psu for the hub at radioshack. as I said elsewhere the only cable I like better than Belkin gold is $1,000usd. I "like" it better. I never said it "sounds" better!

LOL! :biggrin:

Or can I just use AQVOX power supply, is it same as powered usb hub with regulated psu?

 

post #895 of 1636

yes indeed. what I suggested should run you $30 though. same thing. ifi is a little nicer but pretty much all the same thing. one warning. if you do the hub with psu do not plug any other usb devices in it. it will cause noise and overload that psu.

I got a very long Belkin Gold with my OR5 and it is noticeably better than the Audioquest Cinnamon USB I was using.  Better bass response and clarity.  The Audioquest sounds kind of dull and muddy by comparison...a result that I didn't quite expect. 

 

Right now I am just using tape to cover the 5v connector.  If I work up the nerve I will try to cut the 5v power line. I would have done it already but I can't find anywhere close that carries the Belkin Gold to get a replacement if I **** it up.

post #897 of 1636

tape is fine. I honestly cannot hear a difference. unless the cable is messed up some how. you either have to be sure you hear a difference or just appreciate that you do. I love the aq diamond. I can't hear a difference from the Belkin but I just dig it. it has to be better. I don't really believe that scientifically but it is my choice. I wonder if anyone that thinks they can hear it thinks the Belkin is better than the diamond. I don't doubt this for whatever reason I just personally can't tell.

Why bother? I use this to bypass the USB power on my converter:

 

 

15 bucks, works perfectly. Then again I'm of the opinion that digital cables cannot change the sound. Figured there's no point in spending a fortune on something as basic as this.

yeah but if you are wiling to spend about $30 no work involved. you still need the psu for yours. so I would say yours is about $30 too. a usb hub with a linear psu will do the same thing. no soldering. oh, I can certainly make cables but not required here. although yours does look very nice. the dirty power should certainly change the sound but perhaps not a fancy cable. I don't doubt others opinions but I think the Belkin is fine. I do have bad usb cables that do not make connection etc. that is a different story.

post #900 of 1636

Sure, I just don't like having devices cluttering up my desk so the cable is a nice alternative for me. As for USB cables changing up the sound, well, that's a debate for the sound science forum so I won't get into it here, but personally I don't think it's possible.
