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.

Mrtennis, what you say is true, but how would one break through the paralysis, or ever be in a position to know that one can make the 100% perfect decision? Until there is a local store carrying every piece of equipment made, with a loaner program to listen in your room before buying - we are left with some collective wisdom deciphered with a little bit of healthy skepticism and a small grain of salt -but surely a careful reading of Audiogon comments can lead one to making some pretty good choices in buying equipment; not sure we have any better way; better than blind faith, but faith nonetheless. Is the EMM CDSA SE the best? Who knows. But if you can't be happy with it and enjoy it, there is a problem that probably can't be helped with another equipment fix.
Pubul57, I think your comments were directed at my posting, if I am not mistaken. I was not talking about a "100% perfect decision". I was talking about a well-informed decision. There is no such thing as perfection as we all know. And there is no paralysis. There is only the process of evaluation. For those who are lucky enough to be able to audition equipment evaluation is a simpler process than for people like me who cannot audition equipment without traveling abroad. So a more complete shoot-out incorporating more variables would have been more helpful. That's all I'm saying.
Sabai, I agree that head-to-head comparisons of equipment can be helpful, and doing blind tests is the most objective way to perform the tests. I don't believe that more variables needed to be introduced (plugs, wires, etc.), though more music selections and a round-robin format would have improved things. The real problem here is that the presence of a manufacturer at the test completely invalidates the results. It is impossible to claim the tests were either blind or objective. The power of biased individuals to intentionally or unintentionally affect the results is far too great to allow them anywhere near a properly conducted blind test. The fact that the organizers thought it was appropriate to have him there is also highly suspect.

It is unfortunate that the people who conducted this test expended so much time and effort to produce a result that is so completely worthless. Hopefully their next effort will be better planned.
i think a good strategy for purchasing decisions where home audition is not possible is the following:

scan the want ads and note what components move fast. note the difference between the asking price and the retail price.

these two data points can help you make a decision, figuring that if you buy a component based upon the above, you will not be stuck with the piece and you might not lose to much.

also, as i have said in the past, many manufacturers are straight forward when asked about their designs.

now you have three factors to consider.

again, not ideal but at least its a plan.

if you want to include recommendations, that would be your choice, of course.
Cbw723, I agree that the presence of one of the makers at the shoot-out compromised the test. At least one of those present was not blind. Subconscious influence cannot be underestimated in such a situation. I also feel that a greater variety of CDs should have been tested. Testing only classical pieces was far too restrictive. But I disagree on the subject of variables. You would never recognize my EMM CDSA SE if you did a blind test before and after the improvements I made to my system. It is like night and day. The EMM has incredible potential from my personal experience. But without the right variables creating the right synergy you might easily dismiss it as an inferior CDP. Frankly, I was disappointed with its sound until I did some serious work with plugs, IECs, cables and tweaks, added the SR PowerCell 10SE, and then did a lot more work with plugs and cables and tweaking. The sound that it now produces is quite amazing, IMHO.
