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.

Bet the only streamed version of this is the 2001 version.

And not the far better 1995 version, which has one less track, and has differently arranged track no. compared to the 2001 one.

Even so I bought my first and only high end CD transport this year.
However if not A B ing the difference is not really noticeable
Yes I would go along with that day to day not A/B'ed, but I think the listening sessions with the streamer would be shorter as the wow! factor would be less.

That tells me very little, other than they probably were influencing one another (or it wouldn't be unanimous).
Before we started it wasn't going to be an A/B between the 2 formats, just get together for a listening session between buddies.
But the 2 "pro streamers" were adamant when the subject was mentioned that streaming was better if not at least equal, to CD. We only up till then were listening to the streamer up till lunch. That's what led to the A/B'ing of the two after lunch, and when they then even quietly conceded and agreed on the difference.
Mind you I'm sure in their minds there were probably excuses to why, but they didn't or couldn't bring them up.
BTW And no there wasn't any MQA played

@georgehif, I understand that there was a unanimous consensus as to a preference. But, was there a consensus as to just how much difference there was between the formats, and if so by how much?
It was enough for all (even the 2 streamer dedicated there) to all say in the first 20sec comparison of the same track "yes that’s more dynamic" Then after 1min came the comments "better separation and was blacker background between notes" after were the comments "you can hear the singer diction is better to understand during complex passages"

BTW the system was super high res, my feeling were the whole time if the Supratek was taken, out and we went direct dac to amp the difference would have been even larger. And then also on a much lower res system things may have evened out more.


@georgehifi Did you compare the CD to a ripped but local version of the CD, say on a local server?
Just the same cd streamed, then copied to the servers HD and then played on the CDT

The streaming crowd do not like to hear the conclusion of the OP and his friends...

Sure its subjective and not a rigorous clinical study but it's a cautionary tale the convenience of streaming MAY have some sonic disadvantages that might need to be overcome or lessened....
You got that right, the two that were there, ended up not very elated at the end, probably because both had sold the 1k+ CD collection they spent decades getting.

Is the 432Evo hardwired to the network?
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.

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.
