Then prove it, otherwise it's just your opinion.
Avet. I would suggest you do some studying and bring yourself up to speed/date.
Here is his chipset.

Noting the following of course.
Ten DAC channels support 16/20/24-bit PCM format for 7.1 channel sound playback, plus 2 channels of concurrent independent stereo sound output (multiple streaming) through the front panel output
So you guys are basically telling him to buy a DAC when he already has one.
Seriously, the lack of knowledge is nuts.
I use sound cards yes, but only for more source outputs as I have five amps. These range from an onboard Recon 3D, to a D2X, SB XFI Titanium and so on. As long as they can play back 96khz you are absolutely fine.
Watch the second video if you don't trust modern onboard sound chips and have a look at the data. I think you will be surprised !
The only time I have ever "upgraded" my sound card was when I had a MSI Big Bang Xpower II X79. It sounded wonderful, but the output volume was so quiet I could hear my PC over it.
I bought a SBZ, sounded good and I liked the card but it still did not offer the kick I was looking for so that is when I got into amps.
I have probably the most neutral amp sensible money can buy, so I use that as a basis when I recommend amps. I haven't used a Filo, but I have used several others as well as the one I am recommending. I now use a Little Dot MK2 with a Graham Slee novo (pre-power) but I would swear all day the MK1 sounded every bit as good. It's an amazing amp for the money, that is why it's been around for so long.
But hey, buy whatever amp you want. All I am going to hold solid on is the amp part. I truly believe you do not need a sound card nor a DAC, why would you? you already have both !
