the speaker that using usb cable only.... How to configure it?

As far as I know, it'll need some mod. Cutting some cable here and there etc. With what I've in mind, it'll lose the usb only connection function. There may be some other way though.

Let's hope that chchyong89 have a different answer. (He responded to your question at his other topic btw.)

There are two conditions

1. the USB speaker has it's own DAC and USB power amplifier inside the speaker.

2. It using USB amplifier but still need the signal feed from outsource. For example laptops' sc or DAC. (Which usually they have two cables, one is USB and one is audio jack.)

Let me know the model of the speaker will do.

Logitech S150

Hi, it has it's own dac inside. Getting another pcs of DAC can't work
on your speaker

Hi, I'm noob to this field. I'm going to get my AKG K701 soon, and i would like to connect my headphone to a DAC, is this able to drive the headphone?

DAC's job is to improve the onboard soundcard in ur laptop/desktop. The one which drives the headphones is called amp, not DAC.

Thanks sifu. So in order to get a enjoy music with the headphone i have, i need to get a amp to drive the headphone, and dac to improve the sound quality?

This DAC acts like an external soundcard. Amp is to amplify the wave or like adding more "power".

If u seriously have to choose between the two, I'd recommend u to get a decent DAC first. If ur source is bad, no matter how good is ur headphone and amp also useless. Rubbish in rubbish out

yeah this is actually is sound card .... i sure is better than those normal sound card due is using BB DAC

The dac section is wolfson DAC

x2..
Rubbish in, rubbish out, so without a good DAC, we are basically amplifying rubbish source..lol (provided we use an amp)

HI .. i wan to ask about ?? if my SPeaker S330D or S530D .. is it need it ?? and mine is laptop ... is it suitable ? or is it better to get another external sound care like Asus XOnar U1?

Meaning you still need an amp after all?

I am using a multimedia speaker which I believe it comes with an amplifying unit inside, I don't think anyone would use an amp to connect their multimedia speaker right..

Also if my headphone is something easier to drive, amp can be rather optional too right?

Yes. My Superlux is driven easily by the DAC. Any more 'oomph' will require amping..

Another stupid question to ask, possible to pair up this DAC to Logitech Z-640?

this dac practically works with ANY multimedia speakers.

Multimedia speakers = computer intended speaker sets.

Usable, but you won't get real 5.1 sound unless used with 5.1 source and sound card. Anyway, the Z-640 have what it called the matrix button for 5.1 sound simulation. Just connect the green 3.5mm jack to the DAC and enjoy.

Anyone know how does the Wolfson usb dac and the beginner usb dac that being sold by chchyong89 compares with Asus Xonar U1? Which one could provide a warmer sound as I intend to pair with C3. Please help!
