Blind Shoot-out in San Diego -- 5 CD Players


On Saturday, February 24, a few members of the San Diego, Los Angeles and Palm Springs audio communities conducted a blind shoot-out at the home of one of the members of the San Diego Music and Audio Guild. The five CD Players selected for evaluation were: 1) a Resolution Audio Opus 21 (modified by Great Northern Sound), 2) the dcs standalone player, 3) a Meridian 808 Signature, 4) a EMM Labs Signature configuration (CDSD/DCC2 combo), and 5) an APL NWO 2.5T (the 2.5T is a 2.5 featuring a redesigned tube output stage and other improvements).

The ground rules for the shoot-out specified that two randomly draw players would be compared head-to-head, and the winner would then be compared against the next randomly drawn player, until only one unit survived (the so-called King-of-the-Hill method). One of our most knowledgeable members would set up each of the two competing pairs behind a curtain, adjust for volume, etc. and would not participate in the voting. Alex Peychev was the only manufacturer present, and he agreed to express no opinion until the completion of the formal process, and he also did not participate in the voting. The five of us who did the voting did so by an immediate and simultaneous show of hands after each pairing after each selection. Two pieces of well-recorded classical music on Red Book CDs were chosen because they offered a range of instrumental and vocal sonic charactistics. And since each participant voted for each piece separately, there was a total of 10 votes up for grabs at each head-to-head audition. Finally, although we all took informal notes, there was no attempt at detailed analysis recorded -- just the raw vote tally.

And now for the results:

In pairing number 1, the dcs won handily over the modified Opus 21, 9 votes to 1.

In pairing number 2, the dcs again came out on top, this time against the Meridian 808, 9 votes to 1.

In pairing number 3, the Meitner Signature was preferred over the dcs, by a closer but consistent margin (we repeated some of the head-to-head tests at the requests of the participants). The vote was 6 to 4.

Finally, in pairing number 5, the APL 2.5T bested the Meitner, 7 votes to 3.

In the interest of configuration consistance, all these auditions involved the use of a power regenerator supplying power to each of the players and involved going through a pre-amp.

This concluded the blind portion of the shoot-out. All expressed the view that the comparisons had been fairly conducted, and that even though one of the comparisons was close, the rankings overall represented a true consensus of the group's feelings.

Thereafter, without the use blind listening, we tried certain variations at the request of various of the particiapans. These involved the Meitner and the APL units exclusively, and may be summarized as follows:

First, when the APL 2.5T was removed from the power regenerator and plugged into the wall, its performance improved significantly. (Alex attributed this to the fact that the 2.5T features a linear power supply). When the Meitner unit(which utilizes a switching power supply) was plugged into the wall, its sonics deteriorated, and so it was restored to the power regenerator.

Second, when we auditioned a limited number of SACDs, the performance on both units was even better, but the improvement on the APL was unanimously felt to be dramatic.
The group concluded we had just experienced "an SACD blowout".

The above concludes the agreed-to results on the blind shoot-out. What follows is an overview of my own personal assessment of the qualitative differences I observed in the top three performers.

First of all the dcs and the Meitner are both clearly state of the art players. That the dcs scored as well as it did in its standalone implementation is in my opinion very significant. And for those of us who have auditioned prior implementations of the Meitner in previous shoot-outs, this unit is truly at the top of its game, and although it was close, had the edge on the dcs. Both the dcs and the Meitner showed all the traits one would expect on a Class A player -- excellent tonality, imaging, soundstaging, bass extension, transparency, resolution, delineation, etc.

But from my point of view, the APL 2.5T had all of the above, plus two deminsions that I feel make it truly unique. First of all, the life-like quality of the tonality across the spectrum was spot-on on all forms of instruments and voice. An second, and more difficult to describe, I had the uncany feeling that I was in the presence of real music -- lots or "air", spatial cues, etc. that simply add up to a sense of realism that I have never experienced before. When I closed my eyes, I truly felt that I was in the room with live music. What can I say.

Obviously, I invite others of the participants to express their views on-line.

Interesting. How many hours of operation had been previously logged on each player? E.G. my X-01 Limited continued to change/improve up to approx the 1200 hrs mark. Incomplete/uneven break in states would soften validity of any findings. I wish that a well broken in TEAC P03/D03 combo had also been included, as this player is priced similarly to the top contenders present to the event.
Thank you for the correction Ctm_cra. Actually yours is rather a clarification, as I had no prior hypothesis of the relative state of any of the test machines. I should like to point out that a TEAC UX-1/X-01 derivative with 200 hrs of playing time on part of the circuit and 20 on the balance is not at all a well broken in device. . . likely 80% of break in is still ahead. How many hrs of playing time had been logged on the other contenders? Next time the shoot out is conducted I suggest all units be fully broken in. The condition would harden your findings.

Bravo for choosing several excellent orchestral examples, of which at least the Bernstein is delightfully bruitistic. I also suggest next time some subtler selections, from jazz and especially chamber music, be included to gage low level detail, microdynamics, harmonic development, etc. . .

Now on the Wilson/IPOD test. . . I have been present at such an event and was not fooled for a minute. .. is it perhaps because I listen to music only through my ears?
Once upon a time, Donald Rumsfeld wrote the following verses:

"As we know,
There are known knowns.
There are things we know we know.
We also know
There are known unknowns.
That is to say
We know there are some things
We do not know.
But there are also unknown unknowns,
The ones we don't know
We don't know."
Oops... my apologies folks... if anyone was slightly befuddled by my quote from the unwitting poetic opus of Donald Rumsfeld.... the post was meant for a completely different thread.

G.
Difficult to say of course... Mr's Rumsfelt vatic pronouncements are oft replete with sybillic fumiginosities.... uhrn, I meant to say ambiguities... Besides, who knows... the aphoristic bard may be a long-suffering closet audiophile.

G.
Now whilst returning our unlamented hero to his private poetic devices.... TEAC America has just introduced the K-01 single box flagship player to the US market. Does anyone have plans to listen to it and compare it to various other top flight single box units?

Sabai, yours is a very commendable goal indeed... May I suggest, or better strongly recommend--I should even say urge--for you to open a dedicated thread, where you will impart and share your magisterial knowledge on the subject... An thence leave this old thread to its original intended topic.

Unfortunately, OT posts are fun for a spell, but they share a remarkable lot with house guests and fresh fish alike... You know, after three days....

Best, and Happy New Year everyone!

G.
Sabai, as my gentle chiding and humor does not appear to be effective, let me spell it out to you.... Your Messianic/Obsessive/combative posts are being perceived to be OT and disruptive...

Yet, please feel free to continue until such time that your overvigorous posting is moderated to a screetching halt in the most Kafkian of ways by the unseen entities behind the Audiogonic corporate veil.

Regards, G.
"I'm on to your game with APL and other posters in this thread. With a little help from my friends I traced all
of you back in earlier threads ..."

Oh wow.... Yes, you and your imaginary friends have finally rooted our darkling digital conspiracy out.... Time to confess... Alex, I, and all our cryptocohorts are all agents of Philip Jose farmer's Ethicals out of The Dark Design, with a little help from black helicopters and a sprinkling of some good Trilaterals of old.

Our secret goal is to coopting Mr. Tennis into consuming vast amount of overspiced industrial pizzas, and to become the ultimate seeker of the ultra-detailed in 60 seconds triple-blind digital shootouts.

But do not tell MRT and TVAD... They are still under the pius delusion that I am a harmless if somewhat eccentric Esoteric, Roland, and vienna fan, and not a powerful mafioso Don, and prime co-conspirator of the last of the great Bogomil audio-maguses from the wilding Bulgarian Carpatians.

Saluti e buone cose, G.
"it becomes obvious why the the blind should never be in a shoot out"

Uhrn.... except for being caught in the 'crossfire', any other ominous danger lurcking for 'the the blind'?

"popularity does not signify importance when a purchasing decision is concerned ?
"

Golden words MRT!
