I don't think windows7 has kmixer effects like XP.

So ASIO should not sound any different than WAV.

for the record, PCM270x DACs (PCM2702, PCM2707, PCM2704) can be considered the most basic form of DAC designs available (EDIT: ala cmoy of the DAC category) and they all belong to the same family.

Performance wise they should all be the same. As a hokkien would say, LPPL.

Technically all onboard DAC should be using the same DAC chip? Then there's no point getting this?

on board DAC uses Realtek/OEM based DACs, which is not as good as the PCM270xs


PCM270x is the sort of entry level DACs you get at a decent price, that sounds much better than computer on board DACs.

laugh.gif Yep, the PCM270x is a god sent to many beginners looking for an entry level external DAC that sounds decent. This is one of the few things that you get below RM100 and if it's any more than that becomes impractical.

I'm quite happy with the fact that there are owners here that are willing to case it up themselves.

laugh.gif Good for all of you.

A hobby means nothing if you do not get your hands dirty.

WARNING: Other sound effect other than the foobar will be very loud if you do as following:

For people using foobar, I have a solution for this to get back the lost resolution

Go to preference-> Playback -> ReplayGain->Preamp
Set the both with rg info and without rg info to -20.0db (Left most position)

Then go to your windows volume and set it to max. Now you will control the volume through the foobar and not from windows.
Another info is ASIO driver support this DAC very nicely, you get even cleaner sound from ASIO. For ASIO installation please ask uncle google.
Thanks chchyong89 to point this out,  now it's there is really fine sound flowing into my ears.

it does not matter. You should not control your volume using software attenuation because you'll lose bit resolution no matter what.



The best way is still to use an amplifier and control the volume using that device. As for clipping prevention, all you have to do is to replaygain all your songs (prevent clipping mode) and they'll be fine.

I prefer not to use ReplayGain at all, since I consider it altering the original sound.

it does not.

It only normalize the internal gain.

In fact, sometimes if you don't use it, the clipping will ruin your original signal.
