Asus Xonar HDAV 1.3 Slim PCI Soundcard

Subjective Sound Quality and Video Quality

Sound Quality
 
Music
To test the performance of the Asus HDAV 1.3 Slim I played a large variety of music from my eclectic collection, including playing CD's and extracting high quality FLAC recording  from several CD's. I have tried to cover a large range of music genre's to ensure I tested all aspects of the sound coming from the card. Note I also listened to normal MP3's and AAC compressed tracks to ensure I portrayed a 'real world' situation.

Note that being a totally digital card, I could only output music through a digital out into my Yamaha DSP-AX863SE. I did listen on headphones connected to the AV Receiver as well to ensure I wasn't missing out testing, however.
 
It is worth noting that this means that all listening with the HDAV Slim was performed using the awesome Burr-Brown 192kHz/24-bit DACs that reside in my Yamaha DSP863SE, rather than any onboard DACs on the card itself.

Example tracks used:

• Sultans of Swing - Dire Straits
• Adele - Chasing Pavements
• Bloc Party - Luno
• Bob Marley - Three Little Birds
• Chemical brothers - Block Rockin' Beats
• Damien Rice - Cannonball
• Foo Fighters - Skin and Bones
• Fugees - Killing Me Softly
• Goldfrapp - A&E
• Jamariqui - Virtual Insanity
• Jeff Buckley - Hallelujah
• Led Zepellin - Black Dog
• N.E.R.D. - Lapdance
• Pendulum - Slam
• Prodigy - Omen
• Robert Miles - Children
• Roni Size - Brown Paper Bag
• Snoop dog - Beautiful
• Paul Gilbert - Radiator
• Paulo Nutini - New Shoes
• Orbital - Halcyon & On & On
• Melody Gardot - Les Etoiles
• Richard Wagner - Ride of the Valkyries
 
 
Blu Ray
 
One of the main tests to be performed on the Asus HDAV 1.3 Slim was the playback of Blu Rays. To do this, I ensured that I listened to all Blu Rays below using:
 
• Either the DTS-HD Master Audio or the Dolby True HD bitstreamed audio
• The 192KHz Linear PCM sound (converted by the HDAV 1.3 Slim)
• The 'core' DTS or Dolby Digital audio stream on the Blu Ray disc.
 
The Blu Rays used were:
 
• Monsters Inc (DTS-HD MA)
• Quantum of Solace (DTS-HD MA)
• Twilight (True HD)
• The Dark Knight (True HD)
• The Matrix - (DTS-HD MA)
• Foo Fighters - Live at Wembley Stadium (LPCM, DD)
 
 
DVD

I listened to the following UK DVD's using Cyberlink PowerDVD. I listened in both headphone and surround mode. DVD's used:

• The Matrix (DTS)
• Lord of the Rings: The Two Towers (Dolby Digital)
• The Bourne Identity (DTS and Dolby Digital)
• Bowers & Wilkins - A Sound Experience
 

Sound Quality - Music (Digital Sound)

Digital Sound from the Asus HDAV 1.3 Slim was good quality and clear throughout all my listening. Using 192KHz PCM for music, the card output a plain un-fussy sound that had a good amount of detail in it. I've found PC sound cards can be a little lacking in bass detail using digital out but the HDAV 1.3 Slim didn't seem to suffer too much from this.
 
It's worth noting that the music quality from the card didn't have that something extra that was present in the Essence STX in bundles, and there to an slightly lesser extent in the Auzentech X-Fi Forte. Whilst the Burr Brown DACs in my Yamaha AV Receiver did make the sound full and detailed, the previously mentioned cards made music just that little bit more pleasant to listen to.

Sound Quality - DVD's

MATRIX  LORD OF THE RINGS  BOURNE IDENTITY

With the Asus HDAV 1.3 Slim passing Dolby Digital or DTS sound straight into the Amp using ArcSoft TotalMedia Theatre, DVD is a good test of the card.
 
Sound quality on DVD was excellent. The card passed through the surround sound to the Amp perfectly and positioning was spot on. Explosions were big, shards of glass went flying around me and voices were clear.

Now for the important bit and what you (most likely) have been waiting for.
 
Did the Asus HDAV 1.3 Slim pass High Definition audio, unaltered, to my High definition ready Av Receiver?
 
DTS-HD Master Audio  True HD
 
If you'd care to look at the two images above, top left corner, you'll see that the Amp was receiving proper unadulterated HD Audio. I even got a spare set of speakers hooked up to prove that 7.1 was present, where available on the discs and had no issues at all.
 
HD Audio is all it is cracked up to be with gorgeous sound positioning, spectacular back-pounding explosions and precise positional audio that really immerses you in the film 'experience'. Owning two stand-alone Blu Ray players and a PS3 I know how it should sound and am 100% confident that the Asus HDAV 1.3 Slim is doing nothing to the sound. Whilst that doesn't sound hugely impressive, it is exactly what the doctor ordered and exactly what the card is designed to do.
 
As such, the HDAV 1.3 slim gets top marks in the film part of this review, surpassing everything we have reviewed before.
 
 
Video Quality
 
The Asus HDAV 1.3 Slim also passes the HD picture to your monitor or TV via HDMI. It does this by taking the HDCP enabled picture from your graphics card via DVI-D, adding the audio and outputting all through an HDCP-enabled HDMI port.
 
To briefly test picture quality I simply compared the picture directly from the DVI-D port of my graphics card to the picture from the HDAV 1.3 Slim. I then input this into both the Panasonic TH-42PZ80B Plasma TV and my Dell 2407WFP LCD Monitor.
 
The picture signal was exactly the same when compared between the sources and screens, which is excellent. It is worth noting that it does take some of what can only be described as 'fiddling' to get the picture right from my graphics card onto the TV, but I got there in the end and it was worth it.
 
Fiddly
 
At this point I want to try and describe what I mean above by 'fiddly'. Getting music from the HDAV 1.3 Slim requires that the HDMI output from your graphics card is on. This means that for users like me who like to have the TV as a secondary source, your AV receiver must be on and the output enabled in the Nvidia (or ATI) control panels for the sound card to output audio.
 
Whilst this would not be an issue for a dedicated HTPC sound card, it does mean that if you wanted to listen to some music without a TV on, you'd have to set the sound playing, then switch off your TV, leaving your Amp on.
 
 
On a related note, being a purely digital card means that you MUST have a sound processor of some sort. This will not be an issue for those who are in the market for this card to use as an HTPC, but please note this if you are thinking of buying it in a more casual capacity.
 
 
Sound and Picture Quality Summary
 
The sound quality on the Asus HDAV 1.3 Slim really is very good. Music is detailed and clear with good depth, if lacking a little something added by the DACs of some previously reviewed cards.
 
Movie sound quality is fantastic and no matter what format you pass the sound into an external source, it is very good. Picture quality is also excellent and matches the source it is being taken from so no quarels there.

Featuring full bitstreaming HD Audio and only digital connections on-board, will the slim version of Asus's HTPC sound card be a winner?

+ Fantastic high Def sound

+ Decent enough value for money



Think these are the key things. Good to see that the pass-thru is not molested. Tipping the balance is the bundle.

U spend cash on a card that u may think is borderline too much and it hasn't got a good bundle and it makes it worse.

It has a front panel header on the pcb, does that qualify as atleast half a point deduction from it not having an analogue output ?

Great review, like to see u get ur hands on a mobo with ALC889a, like a Gigabyte flavor, just to see how u like it in comparison.

Yeah it gets half a point but I don't think a full point is warranted.

If a company wants to provide me with an ALC889a mobo I could review the audio, but I don't think they'd just be after an audio review

Just an FYI (and tbh I can't believe it worked first time myself).

Got a thread to post in it's own right which may come sometime sunday, but:

Take 1x Abit IX48 GT3 (Onboard RealtekHD, just ALC888), DTS 5.1/7.1 available.

add 1x Quality built (even with loud cooler) EN9800GT gracious prize from ASUS

Throw in, Vista 64 bit, Q6600/4g.

Connect the spdif (optical) out from the onboard to the spdif (yep the gfxcard actually has an optical input aswell as a header for coax).

Download VLC, take a cheap 5m HDMI cable and connect it from ur Samsung L32 (setup as a 1920x1080i resolution), and hmmm we have audio whilst watching Matrix Revolution

Excuse the bumpage, but this hasn't worked since...
