SACD vs. 24/192 stream


I recently acquired a Innuos ZENith Mk3 streamer, replacing my Bluesound Node.  I've come to appreciate what the Mk3 adds--more low-level detail, clearer soundstaging, slightly better bass.

I repeated a comparison I did with the Node--comparing "The Priest" from Joni Mitchell's Ladies of the Canyon via MFSL SACD vs. Qobuz 24/192.  The latter should provide higher resolution sound than an SACD, according to this article: https://www.mojo-audio.com/blog/dsd-vs-pcm-myth-vs-truth/.  I played the SACD on my Cambridge Audio CXU universal disc player, which uses an HDMI cable to feed a Geerfab D.BOB that sends a DSD signal to my Denafrips Venus 15 DAC.

The result this time was similar to my previous comparison.  The SACD revealed greater soundstage depth of Joni's guitar, and her vocal was more realistic (marvelously so) than the hi-res stream.  

Given that I'm using a very good streamer and just a mid-level sort of disc player, I would conclude that I prefer the sound of DSD to PCM. The article I reference above suggested that an R2R DAC (like mine) should sound better with its native PCM than DSD, whereas Delta Sigma DACs sound better with DSD.  I'm not so sure that's true with my system.

So this gives me reason to continue to use SACDs and keep an SACD player in my system.  Generally, I find that high-res streaming is superior to Redbook CDs.  That was evident even with the Node, which I think punches way above its price, especially when upgraded with a good linear power supply.

What have others of you found when comparing hi-res discs with hi-res streaming?

Well you might though differently if you had stepped one up from mk3 to say pulsar. 

Innuos really changed gears there and not to mention zen NG and then again zenith NG. 

If you get the opportunity to try any of the above mentioned to compare do it and you will be surprised how much more streaming have to offer 🙂

@iseland   It's nice to know that spending twice as much would reduce this small difference; but at my income level, it wouldn't be worth it--I'm guessing the Law of Diminishing Returns really applies when you get to those price levels.

Overall, I'm very happy with the sound of my system, whether listening to streaming or other sources.  Only careful AB testing revealed the difference I noticed, and it certainly doesn't diminish my enjoyment of the music. However, I would say the greater realism of Joni's voice on the SACD augmented my enjoyment, so if a better streamer does that, maybe it is worth it to those who can pay the price.

@drmuso what Interface and cable are you using between InnuOS and Denafrips?

That’s a very important detail and that’s where you can level the playing field. 

@audphile1   I'm using a $500 Transparent USB cable between the Mk3 and the Venus 15.  It was included with the used Mk3, so I believe both were already well broken in.  The Venus' hard drive had a lot of the original owner's music on it.

And when you’re doing the comparison are you using the same digital cable? 
In my experience with multiple DACs and streamers using DSD files the results are not always a clear cut. It would heavily depend on the source material (album, mastering, remaster, etc.). 
Try running a comparison with the same digital cable even if it means disconnecting from d.bab and connecting it to innuos. 
 

As a side note, I’m not familiar with Transparent USB cable. The $500 price doesn’t mean it’s any good. Best USB cables I ever used are AQ Diamond and Audience Studio One. They make a huge difference. 
Also, if you have any Ethernet filters on your innuos, remove them for the purpose of the comparison. I’ve had filters mess up the sound of streamers like you wouldn’t believe.
