1. It works fine when powering it with a portable battery pack. 2. The pack stays on while the device is in use. The cable has only +5V and GND connected to the external in on the eval board. 3. It does sound better to my ears. There's more impact, highs are not as harsh. Defrinitely worth taking another step so I'm going to make a data only cable with some mil-spec shieled 3 conductor wore from navships and USB connectors from mouser

I'm about to find out if it makes a difference. Klaus the cat chewed through a lightning cable the other day so I'll use the USB A end to test out the portable battery pack.

lol!!! I love it. In hind sight it was a bit odd that there was dim lighting and wood paneling on the walls

Indeed... It's not as bad as it seems. To each his own, but for me I reached a point where I couldn't take it anymore. The real story is that it made me a bit more aware of what I'm eating and made me at least add fiber and fresh vegetables to my everyday diet. Or every other day lol!

Yeah, I'd have to crack it open to see what's regulating the power. It's kinda like the older ipods where there's a face plate that's only held on the front with adhesive. I'm afraid if I peel it off it'll bend and look shitty when I put it back together.

I know Steve's gonna have field day with this but... I once had the same issue. Found a wellness clinic that did colonics. I got one, albeit humiliating. It worked like a charm. It got whatever was eating my gut. Haven't had a problem since and I'd say that was 10 years ago

Yeah, I'm going to make a data only cable with some mil-spec shielded wire and see what happens

I picked up one of these off ebay to isolate the dragonfly http://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EVAL-ADUM4160.html#eb-overview It's really neat, solved the noise I was hearing with my tube gear. It allows you to use bus power, isolate the bus power and provide your own while also providing the downstream power. Or, you can provide separate supplies for both up and down. I'm using bus power right now, but will experiment with a separate supply. I was thinking of using the power output from one of those portable battery packs. Does anyone know if the power from those are noisy? In theory it would be cool to have a battery supply but I have no idea how the voltage is regulated and it could be just as noisy as the bus power.

That isolation eval board is pretty cool. It cured the noise I was hearing when using the dragonfly with my tube gear. I'll eventually be making some cables to see if there's any difference. Does anyone have a good source for A and B connectors and hoods? I found these at mouser, but they don't have hoods https://www.mouser.com/Search/ProductDetail.aspx?R=KUSBX-BP-KIT-SCvirtualkey51700000virtualkey806-KUSBX-BP-KITSC https://www.mouser.com/Search/ProductDetail.aspx?R=KUSBX-AP-KIT-SCvirtualkey51700000virtualkey806-KUSBX-AP-KITSC

She voiced my favorite doll https://en.wikipedia.org/wiki/Living_Doll_(The_Twilight_Zone) Killed Telly Savalas but good The mom in that episode was hot... definite MILF material

I picked up one of these for $23 on ebay http://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-kits/EVAL-ADUM4160.html#eb-overview

Hmm... I'm also wondering if I have to or if it's possible to isolate the ground. I must connect D+ D- and GND to the PC for the device to be recognized.

That's a cool looking little device. I shall read through that. I knew the dragonfly was noisy. I only paid $50 bucks for it and was looking to use it only for travel. It works fine for me in a pinch but of course I feel like tinkering with it a bit. gonna get some $1.00 cables from monoprice and see what happens

I want to see if cutting the power from the PC reduces the noise Indeed, that's what I'm after. Specifically I want to see if cutting the PC power and replacing it with a better supply will lower the noise coming from the dragonfly. I intend to get one of those ifi isolator/re-clocker boxes but before dropping the $200 I wanted see see if I could do something with what I had laying around in regards to the power side of it.

I want to experiment with making some data only USB cables. Looking at the specs of the bulk USB cable by lcomm it shows 28awg twisted for the data lines. Is it ok to use stranded?
