To DDC or not to DDC. That is the question.

My DAC, a Schiit Yggy, has USB galvanic isolation (Unison 5 card) and when I tried an entry-level Denafrips Iris, it made a fair enough difference for me to sell it and buy the top dawg Gaia. The Gaia was a revelation. Everything got better; the DAC had the same sonics after the upgrades - it did not change the character of the DAC.

Used a DH Labs AES cable and then an Acoustic Zen MC2, resulting in another audible step up. Both can be found used at a reasonable price. Like others have said here, I thank those here in this forum for such advice!

Considering the quality of the OP's DAC, I would urge him not to bother with any other DDC besides the Gaia. His DAC may have jitter control that equals a Hermes, so it may just be an exercise in futility. If one has a recent 6K DAC, buy the best DDC available. 

And, here me out on this...the OP's DAC weighs 17 lbs. The Denafrips Gaia DDC wieghs 14 lbs. 

Why does that matter?

When you talk about reducing jitter, you are aiming at reducing vibrations. Jitter is mechanical or electronic vibrations. Jitter is internal to the unit that it resides and is passed through to other components. 

I will resort to AI to explain:

Jitter is defined as a small, rapid, and often periodic mechanical vibration or oscillation. While sometimes used interchangeably with vibration in mechanical contexts, in optics and electronics, it specifically refers to high-frequency, involuntary motion or timing irregularities in a signal, causing instability, image blurring, or data errors.

The two most expensive parts that make up a DAC are the chassis and the power supply. So, if your DAC is fairly lightweight, it will inherently have internal vibrations that need to be addressed. 

If you want the best DAC/DDC combo in one package, you will need to spend a lot more and, in some cases, the DAC may come with an external power supply as putting all of it in one chassis can match heavy turntables that are heavy for the same reason that DAC's need to be.

The heaviest DAC's are generally the most expensive. However, I have noticed that the Hegel D50 is only 14lbs -and includes three master clocks!- so maybe jitter can be reduced without using weight (think Rega TT designs), but generally speaking, most reference DAC's range between 40-180 lbs of weight...for a reason!

Additionally, plenty of shielding to reject EMI, both internally and externally, is another contributing factor of the components weight. 

@zlone I know right? It’s always an upgrade…at least we call it that even if it’s for worse. Lol

Here’s a bit of bitter truth…you can throw more money into streaming but you can’t fix bad source material. Depends on what you’re listening to, it is mostly a crapshoot. Most high res isn’t truly high res, it’s a remaster to high res. Padded bits don’t make it sound better. Some of the stuff is good, some of it is pure drek…well most of the remasters are. Convenient AF though.

Along those same lines, my latest DAC has a built in CD player. I grabbed a bunch of old cd’s (I am very happy I kept them all) and one of them is Van Morrison- Moondance. 

Threw it in and it sounds absolutely perfect, my head is completely absent of upgradeitis- the system needs nothing- no cabling changes for better highs, no better digital cables for less noise or less digititis, bass is perfectly defined- everything is pure and natural. Listened to the whole 39 minute album start to finish, twice in the last few days, and it is glorious in its musicality. Never done that before, typically I would listen to a few of the songs and go on to something else. 

I look at the CD and can’t find a date anywhere on it, but it says "the music on this compact disc was originally recorded on analog equipment.... because of it’s high resolution, the compact disc can reveal limitations of the source tape" 

I hear no limitations at all  Sounds perfect. 

Who needs high res? (Well, that is a bit of a lie, the player does it internally)

@mclinnguy yes exactly. The amount of musical information a good player can extract from a well recorded redbook CD is astonishing. On a surface at a first listen you go yeah it sounds similar or even the same as streaming. Then a minute into listening you are fully engaged and the music demands your attention. That’s the difference…musicality. Streaming, involuntarily, becomes a background type of listening. With skipping songs and albums looking for something that will eventually grab your attention but it never does.
