Yes, I doubt that leaving the gain at lo/med/hi has any adverse or benefecial effects to the DX50. I leave mine at low gain and don't adjust it unless I'm using higher impedance/low-sensitivity phones using the headphone out of the DX50 only. When connected to the C5 it's on low gain, just because I like it to be there

When connected to the C5 the headphone out will be the C5's. The headphone out of the DX50 won't be used unless you plug your amp or phone into it.

Thanks for answering my questions man. I really appreciate it!

No problem. Glad to be of help!

Keep in mind that since the outs for the C5 and the DX50 are above/below each other, and that you are running the DX50 at full (255) volume into the C5, if you accidentally plug your phones/iems into the wrong hole it's not a nice thing.  I've taped over the HO on the DX50 to avoid doing this (again).

Sorry for your (hearing) loss.

Thanks for the warning. btw, when pairing the dx50 with an amp, should I really turn the volume of the dx50 to max volume?

JDS Labs says yes, many here say yes, a few here say keep it at maybe 250.  I run mine at 255 with no issues (except when I plugged my iems into the wrong out!).

Personally I don't keep it (the volume) on the DX50 that high. On stock firmware an through lineout my volume is set to 240-243. On rockbox it's around -6dB. It's just a personal preference thing since by lowering the volume by a little I get to adjust the volume of my sensitive IEMs more finely in smaller steps using the C5's volume control.

With the Duet I have the volume on the DX50 set at 245

I purchased a bunch of headphone jack dust plugs to solve that problem.

1. The battery will be drain faster If you are running DX50 at full volume (with an amplifier)?
2. Does DX50 gain do any difference when it connect to any portable amplifier?

 

[olddude]

Gain on DX50 does nothing through Line Out.  Battery drain?  I haven't seen any.

 

[Vemon]

I mean does the music volume affect the battery consumption of the DX50?

 

[Gabriel12]

How would you describe the increase in sq when the dx50 is paired with the c5?

 

[gmm1]

Vemon, the battery will drain somewhat quicker with increasing volume output through the headphone jack. When using a portable amp, you would connect through the line out and the amp would control the volume.

 

[bluesyfluesy]

How would you describe the increase in sq when the dx50 is paired with the c5?

The increase in SQ is quite noticeable.
Soundstage is wider, deeper and slightly taller and more 3-dimensional.
Instrument separation is also noticeably better.
Dynamics are better; without the C5 the DX50 sounds a little boring to me. With the C5 the DX50 sounds fuller and more powerful.

Just some of the changes I noticed.

In my opinion, though.
