1 noob question here: what's DAC? what does DAC do? usually headphone line out no need DAC right?

1.DAC stands for digital analog converter..
2.it coverts digital data to analog
3.no because h/out is from internal SQ not directly from source

Here is a simple explanation about DAC.

Source -> (Digital Data) -> DAC -> (Analog Signal)-> AMP -> Headphones

1) All digital players MUST have DAC.
2) DAC performance varies due to cost saving and size.

So, a separate DAC/AMP do sound better due to better power supply, better electronic design (less noise, high dynamic range) and better components quality. Sometime you can hear hiss noise, distorted or underpowered sound with standard mp3 player or laptop. But with external DAC and AMP, you may get a better sound detail (resolution), more bass umph!!, and deeper bass and more extended treble. You will notice all these with a good ear/headphones.

TQ

I think you got the wrong person, because, she just received the offer letter from USM

Back to topic.
Currently "In Nirvana", listening Diana Krall's album "From This Moment On" with UM3X and D10.. Wow... after 2 weeks, my brain already burn-in with it's sound signature. Now I can appreciate how good are this combinations.

Bass: Wonderful. Secukup rasa. Just nice
Mids/Vocal : No need to say more... Lush... also 'Secukup Rasa'. No exaggeration.
Treble: Eventhough much less sparkle than PFEs, but, it's sound natural. No problem, my brain can adjust it

Overall : Beautiful and well balanced sound.

Hi guys,
It seems dat this thread has been abandoned quite long...

I juz got my unit last saturday and i got a question. Here's the story:

After using it 4 a few days with my laptop as Dac/Amp combo and my DAP as an amp. I noticed dat as Dac/Amp i will set the volume knob around
9-11 o'clock 2 get my preferable listening volume but when i use it as an amp for my DAP i need 2 turn the volume knob around 1-3 o'clock, the volume on the DAP was set on 20 ( when listening with my DAP without amp the volume r usually set around 17-25 )

Is this normal? or my unit r faulty? hope somebody can clarify on this...

sorry if my english was bad... Thank you

It is normal...
This is because the DAC in ur DAP is no as power as the DAC in the Dac/Amp combo..
**the voltage/current output smaller than the DAC in the combo...

9-11 oclock @ DAC mode is normal. Eventhough D10 is the headphones amp, but, it is not as powerful as desktop amp, or the silver amp (as jkleekc mentoned). Yes, everything is about voltage and current. You can try few opamps/buffer combinatons to get more output power.

thx 4 the replies there guyz... really helped 2 clarify this...
i haven't opened the unit yet coz still busy will try the other opamps provided this coming holiday... yeah i've read that different opamps got slight variations in terms of power besides the sound sig...

how to ground myself while rolling the opamps?
afraid that i will fry the chips

sorry for bringing up an old thread
