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.

Meitner or Meridian Signature? In listing the digital gear involved in the shootout you said Meridian 808 Signature but in the comparisons you say Meitner Signature. As stated by Tvad, this stuff is "cost no object" of reach for many of us (the blue book value of our cars can't touch some of these players-mine included and I drive an Infiiniti.) Maybe if I ever move into a different tax bracket......
Pete,

First of all, thanks to you and the other members of the San Diego, Los Angeles and Palm Springs audio communities that organized this shoot-out. Your review was extremely well written and it looks like your process was beyond reproach. These types of reviews are too rare in the world of high end audio and a greatly needed adjunct to "professional reviews".

I have had my NWO2.5 since late December and while I have not had the luxury of comparing it to all of the machines you tested (only the EMM Labs Comb and DCS single box units), I would agree completely with your conclusions, especially the last part that the NWO2.5 brings you the closest to real live music (particularly on SACD and DVD-A). I listen to live music on average once a week - acoustic and amplified - and the NWO2.5 brings me the closest to that experience of any digital source I have heard...and I would go a step further and say that when playing DVD-A and SACD on the NWO2.5 it meets and exceeds several of the SOTA phono set-ups I've heard, although I want to be clear in saying that I have not yet A/B'ed it against the best of the best vinyl rigs.

On that point, I hope some organziation like yours takes on the challenge of doing a similar blind shoot out of the NWO2.5T and a few of the SOTA phono rigs. I think the results would be very interesting indeed. Perhaps SOTA vinyl would still win, but I think the performance gap has been reduced considerably over the past year and will continue to shrink going forward.

Thanks again Pete for taking the time to do this shoot out and share the results.
What a GREAT write-up and a fabulous, state-of-the-art shootout! I like the King of The Hill method, followed by subsequent experimentation to substantiate your findings. Very Cool!

I would love to conduct a similar shootout, but with players that the average Audio nut can afford. Perhaps players such as the Resolution Opus 21, Audio Research CD3 or CD7, BAT Vk-D5SE, APL Modded Denon's, Ayre CX-7e, Cary 303/300, 306 SACD, Meridian, Etc. That would be equally cool.

Thanks for sharing!
Call me a skeptic, or whatever you wish, but the little hairs on the back of my neck tingle when something reads like an advertisement.
Is it the best results of APL NWO player come out when connected directly to amp ? In this test, there is a pre-amp in between.
