Default Asus Xonar U7 7.1 USB Sound Card Review Comment Thread

ASUS' U7 is the latest addition to their Xonar lineup and it takes things to another level. Typically USB sound cards are sub par at best but this one will change your mind.

What OS was used for testing? If this product supports multi channel / 192 KHz / 24 bit digital output under win 8.X then it fills a much needed niche in the marketplace. I went looking for a USB solution w/ S/PDIF output and found user reviews suggesting that the windows 7 based ones were severely borqued under win8 when it came to digital output.

Can you confirm the range of settings for digital out under windows 8.1? (I'm not even sure if AKG is running an 8.1 system yet.... ;) ).

Nope. This is a digital to analog converter, as are other sound cards. You would need analog headphones (ie: connected through a headphone jack).

USB is digital to digital. HOWEVER, some USB headphones have their own DAC like this one: ASUS Orion Pro Gaming Headset Review. I am not 100% sure but you could conceivably replace the the in-line DAC with something like the U7.

This looks promising if they can get a USB3.0 model out with the extra power, just as peace of mind since my headphones are 150ohm. I have always wanted to build a high powered mITX rig but I refuse to give up my sound card.

Interesting indeed! I want to reduce the size of my next rig, and well it's always good to know, like you said LP, that there is an option out there that can help us reduce from atx to matx/mitx without sacrifying our sound.

From my understanding, and from my conversations with ASUS:

- There are no more "true" 24-bit DACs being produced anymore. They all feature some form of shaping to create a "virtual" 24-bit signal

- Neither I nor ASUS have seen a current receiver that can actually receive 24/192 over S/PDIF. Rather, with content that has the necessary bitrate (Blu Ray), HDMI is the chosen output / input format.

That doesn't answer my question though... what are the actual output options available for digital output? As an example, the onboard realtec optical for my AM1 system has a selection for up to and including 2 channel , 24 bit, 192 KHz. Does this device offer that option?

I'm pushing on this because my research on the subject earlier this year showed some very wishy washy information being provided by the manufacturers on the subject making it almost impossible to know what the device was going to offer for digital output until you spend the money to get it into your home, which makes it too late if you've planned a mITX build around using an external USB soundcard.

From my experience, optical audio connections just seem to be more stable and offer better compatibility, and quite frankly, if the preferred method of digital audio connectivity is through HDMI then why exactly are S/PDIF connections even included?

The U7 is an excellent gaming card. I have the Xonar Phoebus,but I bought a couple of these for me and my wife to try. The software and game settings etc. are exactly the same as the Phoebus and the 7.1,5.1 analog provides positional sounds as good as any other sound card I have owned. A great gamers card.
