I think we have to turn the Volume knob for that. :D

 

Not necessarily. The volume knob only attenuates an input signal. It doesn't adjust the gain.

I have a question. I'm running a budget system currently with Sony MA900 as my headphones and using Fiio E17 as my amp and dac. I'm currently using the mini usb that came with my Fiio E17 to connect it to my laptop. I was wondering since I don't have an insanely detailed set-up would there be any benefit to upgrading the mini usb that connects my E17 to the laptop? I was interested in the Moon Audio blue dragon mini usb for $75. Also there is the Audio Quest Forrest mini USB for only like $40 and the Wireworld starlight cables.

 

If they will make any sort of noticeable difference which one would be best for my set-up? I do have mainly 90% Flac files that I listen to btw if that helps.

And thus still lowers the output that would otherwise be double at the balanced outputs.

Right but if you adjust the gain of the balanced signal, you won't have to 'move the volume knob' to get the balanced and single-ended signals to match. See where I'm going with this?

 

You can either convert the single-ended signal to a balanced one or adjust the gain of the balanced signal.

 

In any case, because a signal is balanced does not necessarily mean it will 'sound twice as loud' in the end.

A lot of folks don't have a balanced DAC but use an amp that provides a balanced output from an SE input.

This is different from balanced transmission (what you were originally commenting on). See http://www.headphone.com/learning-center/art-i-balanced-vs-unbalanced.php. Again just because you're using a balanced output topology to power your headphones doesn't mean the volume will somehow increase.

 

And to the rest of the posters - sorry for hijacking the thread.

For some reason I didn't track your meaning with a balanced source. We can leave this OT as is.

That cable would be half the cost of the E17. I would get the Fiio 09 desk amp. Your E17 would dock into it. This will make much more of a difference.

I m a technical disaster....jus know it links my lappy to a dac.
If i had known all the currentscience i might not hv bot my first usb...
A LATusb...quite neutral..clean soundg..threw away my stockUsb tat came with the Nuforce.
Next i had a FurutechGT2...alot more bodyweight. Then a wireworld starlight..
V bright soundg on my setup...night n day vs furutech.
When i finally plugged in the CabledyneUsb...i know its endgame for me
In tat part of my setup....its just 3D to my ears.
From there on...i focused on my powercords..rcas.
These cables are "infrastructure" investment to my hobby...
Feeding the rest of my cans..i didnt mind spendg those monies.
I know my "sonic highways" are not blocked to the best of my wallet..
SO tat ends a chapter.

Ok u guys can carry on with the science tongue.gif

I happen to like blue cables. Get cables that look good and feel durable. Nice soft flexible cables. I'd go for the headphone cables because you handle them all the time and they are highly visible. They all sound the same to me....this is about looks.

In a nontechnical sense, you are doing your part to boost the economy. :p At least one sector.

Now you make sense. Buying them for reasons of aesthetics, comfort and durability as opposed to sonic beliefs.
