Streaming vs CD transport direct comparison



Yesterday we had a day at a friends comparing the title to this thread.
System consisted of:
  • Speakers — Wilson Alexia series 2
  • Amplifier — Gryphon Audio Antileon EVO
  • Preamplifier — Supratek Cortese or Lightspeed Attenuator LDR passive or source direct (we used the Supratek for instant a/b ability)
  • Sources — Digital: 432Evo Music Server Roon Core (owner has found Roon to be the best)
  • Yamaha CD-S2100 as transport,
  • Totaldac d1-core DAC.

We A/B both (levels matched) CD to 432Evo (streamed, saved and/or to H/D) with a number of albums same versions, classical, jazz, soft rock, hard rock.
The overwhelming consensus of all 5 listeners (some that "were" originally very pro streaming) was that the CD was firstly clearly more dynamic, had better separation and was blacker background between notes and it was also clearer through the vocals that were hard to hear what was being said, than what came out of the 432Evo.
This is the third time I’ve sat in on this kind of A/B on different systems all were similar on how the differences came out.
I can say the streamer would be a slightly better late night low volume level system to play, as it’s dynamics wouldn’t wake other people in the same building. Where the CD you’d be running for the volume every time there was a big dynamic passage.

How do you know that the streamed version and the CD version were the same version - that is, from the identically same master?

You don’t mention the streaming source. That’s important, because I’d expect different results from Spotify than I would from Qobuz, for example.
Good question @cleeds.  What was the Service?  Is the 432Evo hardwired to the network?  What was the DAC output resolution setting on the Evo? Roon has a reputation for sucking the life out of a sound stage in certain configs.  The Evo is a cool piece.


Asked him this morning.
He was able to say both were the "year and label". So we knew if it was, 1st release, later remaster, re-release, or reissue. And with the amount of a/b'ing all seemed correct, as all had the same outcome.
And the source was he said was the top tier Tidal which he said was better than Spotify, Qubus is not available here in Au.

We have now the NBN which is all over Australia fibre optic to the premises, and over 100Mbps download and over 60 upload.
And he played the server real time and also saved on the H/D no difference between the two.

Roon has a reputation for sucking the life out of a sound stage in certain configs.
He's a reviewer and owner of Soundstage, and said he found it to be the best.
