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.

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?

fumiginosities...GREAT over pasta :-)

sybillic...they have treatment for that, now!
Napolitana Volanta looks like she's already been consuming a lot of pasta -- looks like she needs a pair of good Horns and a power conditioner to cure her of what ails her sonically and otherwise. Maybe she'll bump into someone at a local audio dealer who can suggest some good power cords -- something high end like SR QT'ed may do the trick. On the component end she seems to be too digitally preoccupied at the moment -- she needs to look at something analogue, possibly.
When I commented earlier about missing "variables" in the shoot-out I am now able to expand on what I was talking about. I have the 1-box EMM CDSA SE. Without a power conditioner it is very resolving with excellent dynamics but the sound stage is unimpressive -- just plain flat. I have tried 2 power conditioners and have settled on the Synergistic Research PowerCell 10SE with the Galileo MPC. I just installed the SR last night, tweaking it with a set of SR MiGs underneath and 4 Totem beaks on top. A set of MiGs went under the EMM, as well. And I replaced the stock EMM fuse with a Furutech green T2A fuse from Japan. The sound coming out of the EMM is like night and day with the PowerCell installed and the tweaks. Frankly, you would not know it is the same player. So, my comments regarding variables and how the shoot-out was conducted stand. The shoot-out was one-dimensional and did not do justice to the EMM, and I presume this must be the case for the other CD players. The sound out of the EMM by itself is two-dimensional. The sound out of it with the PowerCell is 3-dimensional -- and a lot more. The shoot-out was essentially one-dimensional because it did not make any attempt to maximize the potential of the other CD players and judgments were made on the basis of a set-up that was clearly flawed. In fact, the observations of Petewatt at the beginning of this thread are exactly how I would describe the EMM + PowerCell in my system: "I had the uncany [sic] 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." Can the EMM + PowerCell rival the APL in these respects? You would never be able to find out given how the blind shoot-out was conducted. In retrospect I think the word "blind" is an apt characterization of the shoot-out itself. Saying that there was no attempt to make it a perfect shoot-out is really a cop-out. A lot of people went to a lot of trouble to set up the shoot-out. One of the makers was even present. It was set up to end up with a quick winner. This was not simply an informal Saturday night gathering of friends in the basement. The shoot-out did not do justice to all of the players that participated in this "competition" -- by a very long shot. All this having been said, the fact that the APL is a world-class CD player is not in dispute. My comments do not detract from its attributes in any way.

btw: Do you own one of the other players?"<<

I'm just saying...
