Use of Denafrips Iris 12th DDC with computer


When streaming from a computer I am wondering about improvements one might  get from use of this DDC between computer and DAC.  Anyone with experience using this unit this way? Thanks in advance.

@deep_333 +1.

This was the central point behind my earlier message, but it was not described as succinctly as you.

I have spoken to 2 individuals who tried moderately expensive name-brand streamers to replace a music and TV room set of operation similar to what I have. Both told me that if there was any difference in sound quality it was too small for the expense and loss of all the convenience with my current operation.

@firstonetallguy .. Many of these guys may not know how to build a audio optimized PC or have knowledge of computing hardware/software. I think that’s where some of these false belief systems arise.

This is all it takes....

- A high quality, very low ripple, etc PC power supply (seasonic platinum, ~200 bucks) or other...

- small ITX board (without any overclocking frills, ~150 bucks)

- some higher core Ryzen APU, ~200 bucks (i.e. no discrete noisy graphics card involved)

- Put it all in a HTPC case like these ones made by Silverstone (~100 bucks) and it will like a stereo amplifier sitting on your rack, have the same form factor.

 

 

You can undervolt these things so it barely sips any power or generates any spurious noise...or not..doesn’t really matter that much. Use ASIO or Wasapi with your player (like foobar2000) so you lock out any interference from the rest of the OS.....and you’re good to go.............But, when one doesn’t know, he’ll shell out 20k to some vulture for a 1-trick pony that doesn’t sound any better. I can open some of these vulture priced streamers and show you the same 150 dollar itx board tucked away inside. The chassis will be fancy though, to apparent audiophile standards, i.e., justify a pricetag of 20k.

Or....if one’s a PC hardware noob, forget the PC hardware research and custom PC build....Just get a Beelink pre-built mini pc (~300 bucks) fresh off Amazon with a Ryzen 5800H, about the size of your palm) and power it with a high quality linear power supply. Despite its diminutive size, It’s a full blown computer and you can even play some less demanding games on it, not to mention everything else in life you wanna do with your wireless keyboard+mouse sitting on your couch. Since USB doesn’t rely on the streamer or PC’s clock (like toslink, coax, etc), everything just depends on how good a external dac you may have...and how good the DAC's ASIO driver is, who wrote it. It is important to use ASIO or WASAPI with your PC’s player however.

I’ll eat my hat if someone got much better sound out of his 20k streamer or 40k streamer when plugged into the same dac, whatever dac that might be.

Many years ago, I started streaming Tidal with a dedicated laptop. Besides the laptop itself being tricked out, it also had Fidelizer Pro software*, a USBe Perfect, a dedicated LPS - with a custom DIY umbilical cord, a dedicated power conditioner, a dedicated DDC - all with quality power cords.

@sns spent years sharing his knowledge & experience of improving his streaming quality with posts on Audiogon. I listened to his advice. Bought a pre-owned streamer to try out. Within 5 minutes of listening, I put the laptop in storage. Haven’t looked back. Now my streaming SQ has surpassed my CD transport/DAC combo. I discovered that using the DDC with the streamer - improved the SQ even more.

* Fidelizer software turns off PC functions not needed for audio. Besides the Pro version, they have an introductory version that can be downloaded for free.

To the OP, this is how I use my system daily. A laptop USB -> to a Gaia DDC, then out via I2S (or coax) to DAC. It works quite well.

Of course when you use a PC, for best results you MUST have it where the OS doesn’t mess with the output. For example, exclusive driver mode with Qobuz or Tidal. Doing so, the results then (with the USB isolation and reclocking of the DDC) are sonically as good as any streamer I have heard.

Otherwise, if the OS messes with the files the results are less than stellar.

I need the test aspects a nb can provide in my system, and having worked in OEM nb development for over 15 years I happen to have some engineering samples laying around and put them to use ;) But the main reason then I’d use a streamer instead is for example, some of them can realtime upsample at high quality (eg, Lumin). It’s a bit buggy but can sound great for example, feeding DSD (or 8x PCM) to a PSAudio DS DAC for example.

But of course we can also use something like HDPlayer on the PC, something I should get off my slow b*tt and see about finally ;) But meanwhile having offline upsampled some PCM test files to DSD and to 8x PCM for a test to same DAC I can verify it can work fabulous sent through the PC chain (using Foobar player).

PS we are now N America sales and service for Denafrips, working with Mike Lee. The service aspect continues from before but the sales part is new. Adding the Denafrips line to the site as we speak. I would wager that nobody knows Denafrips in N America quite like we do by now, having done service support for several years by now. Looking forward to some great times ahead :)

Just a link to a quickie phone vid in my friend's super system a few months back. Streaming with the Lumin on upsampling out. We were shaking down a pair of  new TK Ultra_EXB7 in there, redesigned (and fabulous) monoblock amps. Also using a super good, highly improved DSD DAC. He also has the full loom of AQ Dragon cables. Some might get an idea at least: https://drive.google.com/file/d/1oo83-tRKe80WWLKD7nkJda-nH12l7vc_/view?usp=sharing

 

@mesch I’m tried to PM you but you must have disabled that function.  Can you PM me please.

@iansr Sorry, I will check out the PM problem. If regarding my BEL amp I replied on that thread. I sold it 4 years ago.
