Android phones and USB DACs - Page 217

post #3241 of 5363

there is no way to find an usb otg cable like the ibasso but with an elbow connector to the phone ?

post #3242 of 5363

I have been looking for a Micro USB Male to Micro USB Male OTG cable with right angled connectors - probably spent 6 hours searching google, ebay, amazon, and contacting random sellers. And it just does not seem like anyone makes them or willing to make them.

What I have seen only is form Venture Craft.

Thanks the venture craft cable is not otg.

You are correct but you could mod it yourself.

post #3246 of 5363

I don't know how to mod it. Do you know someone who could do that for me?

Or - perhaps I could add a female to male OTG Adapter (not cable wire, just adapter connector piece) would work?

You need to open it up carefully with a razor knife and resolder the wires to the correct pinout.

Very bad move from Samsung. Had I known before, I wouldn´t have bought this phone. If anoybody has a way to let them know how they screwed this up. Maybe there´s hope that they can fix this. 

 

The Galaxy Note 3 (i.e. SM-N9005), using Neutron / Poweramp or USB Audio Recorder PRO, can work with an ODAC.

Can someone please explain how a USB cable can result in better sound?

"Anyway, as you can imagine the most important thing is whether or not it actually sounds any different or better than the cheap cable I have. In the past I found that headphone cables make the most obvious difference, then analog interconnects and finally digital cables. That being said the difference this cable made was obvious from the off. It had a typical warm copper sound to it that was very mellow and smooth. It helps tame a little bit of treble glare if presence in the earphone like with the Fischer Audio DBA-02 or Rhapsodio R^2 and gives a nice smooth, buttery tone to the midrange. I also found the old iBasso cable I used to take a bit of life out of the DACs that I knew and loved. At the time I thought maybe Android was just not that good a transport but I can now conclude that the cable was just getting in the way and that this turns my Android rig into one that is truly amazing."

It can't. He's experiencing expectation bias (or he's full of you know what). Theoretically, with the right tools, you could prove him wrong by showing that the exact same ones and zeros are being received by the DAC regardless of which cable you use (unless the cable is actually malfunctioning).

Agree....the bits arrive or they don't.
post #3252 of 5363
Well, while I have never been obsesses with expensive cables, I have to say there is underlying physical sense to such claims. Another question is whether you can hear differences or not.

But just remember, that there are never any bits travelling across metal conductors. There are always all the same good old electrical impulses that do the trick. And as such, they have two key characteristics that are later used to decipher them into "bits": their magnitude and their timing.

IF a conductor can have a MEASURABLE impact on these two characteristics, theoretically it can have an impact on the end product - the sound.

Never used any USB cables more expensive than 15 bucks, and never heard any differences, but I can understand the underlying theory. I just don't hear it - but it does not mean it's not there, is it? smily_headphones1.gif))

You're right and I should have pointed out that timing plays a part as well. Most people who claim USB cables can sound different point to jitter as the reason since there's not much else that could vary but I still question that the signal being received is any different because of the cable. Most people with knowledge on the subject (technical/engineering knowledge on cables and electronics as opposed to subjective audiophile experiences) would tell you that any properly shielded USB cable that isn't malfunctioning will produce the same results and that includes the < $5 ones you find on Amazon and the like.

The only way variance in the magnitude and timing of the electrical impulses could effect the sound is if they effect the resulting digital signal because two identical digital signals will produce the same analog signal on any given DAC.

Not only electrical impulses to deliver 1s and 0s. It really transfers power/electricity (and all its problems).
