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.

What conclusion can one reach? A group of audiophiles in a sighted test with a specific system in a specific room unanimously preferred a specific CD source to a specific Tidal source? That tells me very little, other than they probably were influencing one another (or it wouldn't be unanimous).

One obvious question is, were both sources using the same input to the DAC? It's been reported often that DACs perform differently from different inputs (and that varies by DAC).

And if "top tier Tidal" include MQA, all bets are off.
I have no problem believing that this group preferred one source over another. What I cannot take from the anecdote is any generalizable conclusion.

Having 5 streamers has me commited to their convenience. 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, especially with the best streamer/power/cable combos.
It only depends upon how serious your listening session is.

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

Well, there is NOT a single system on audigon or for that matter I bet anywhere on planet earth that would match any other person's system. So what the OP heard and experienced in his friend's system is valid and true. Now how would the same music source (that exact CD and the exact streaming service) sound on a different system, is out of OP or anyone's hand.In my system, based on the comparison I did, I liked the quality of streaming slightly better than the CD. But again, it is not a dedicated player. It is a universal player. But the DAC remains the same for the CD and the streaming (FLAC/DSF files). So opinions will be different based on our own experiences. Nothing to fret about or claim dominance of one over the other.

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.
