Help with PC Audio Quality vs. CD


I hope someone with real experience can help out with this. I am having a hard time getting the same quality sound from a PC that I get from a CD player. I recently built a HTPC running Windows MCE and ripped all my cd's using lossless compression. I'm using an M-Aduio Audiophile 192 sound card and run a coax digital out of the PC to an external DAC and to my amps. It just sounds flat to me, not that it's not clear sounding, but the bass is weaker, I can hear a harshness that's not there if I run any old CD player to the DAC through the same connection. Has anyone else experienced this? I keep reading in this forum that people are saying how much better the computer transport is in theory, but I have yet to witness it. I heard that the Windows KMixer is the problem. I tried ASIO and Kernal Streaming drivers that are supposed to bypass this, and it sounds clearer, but still not as 3-dimentional and "black background" as a CD player (and I mean ANY cheap CD player, I've tried 3!)

Can someone out there with an external DAC try this and let me know their results? Use a DVD player or anything with a digital out... I don't get it. My soundcard alone cost 3 times as much as the cheap DVD player I tried and it doesn't sound as good. Anyone experience this or have any suggestions?

Here's my system so you can understand the sound I'm looking for.

I have an external MSB Link DAC III Full Nelson that I've been using for years and I really like the sound of it. I've been using a couple Sony CD changers and running them to a MSB Digital Director that will automatically switch between digital inputs, out to the DAC, then to a tube pre and tube power amp (modded dynaco ST70) and out to a pair of Monitor Audio GR10's. This system (with the right tubes) sounds so sweet to me. I'm into the huge soundstage, crisp, smooth sound - melty mid-range... you know, the analog tube sound!

I have experience in recording studios and work professionally in computers, so I have a good understanding of both, so don't be afraid to get technical with me. Any help would be greatly appreciated!!

Gmood1 - Thanks for sharing! I'm going to order me one. Did you buy from eBay or Audiogon? I haven't got a response from the seller on Audiogon yet...

Artizen65 - Thanks for the info. That sounds like a very practical solution. I think I'm going to try the Trends and see how that goes. I'm also going to try it through Vista and let you know if it's worth the upgrade. Take Care,

Ben I bought my unit from Buyoyo.com. The guy on agon is based in Canada. These units ship directly from Hong Kong. If their in stock and you go courier shipping. You'll have one within a few days. The UD-10 units are selling faster than the manufacture can produce them. Their always out of stock. I waited a month for mine..hopefully it will be faster for you.

I'm trying to find a 5 volt AC/DC 1.5 amp power supply converter so I can plug this unit into the wall. Not having much luck! I assume the sound would be about the same as using the batteries.
I ordered the UD-10 from the dealer on Audiogon last week. I will report my findings after I receive it.

If I am using a MAC with the OS X and iTunes 7 - then do I have all those different settings (sample rates, buffer setting, etc.) some of you PC'rs are talking about through ASIO and Foobar? Would someone else who uses a MAC chime in on this?

I am aware of the Audio MIDI control panel which might have some relevance to this but have not messed with it or seemed to need to.
Pardales I wish I could help you with that.Can you use foobar? Just asking because I have no clue. The ASIO is definitely the way to go with the UD-10 using PC. The difference using the ASIO as the output is quite staggering! I tried using the DS:USB DAC and Primary sound driver as outputs. The ASIO was heads above them.

You may want to try that SRC also and see if it makes a difference.

I have a linear power supply on the way. Thanks to a very nice Agon member. This will eliminate the use of the battery supply. Try to find a AC/DC converter that will power the SB3..this same unit will power the UD-10. Make sure it uses a non switching power supply..not the basic wallwart.
