Cbw723, I really hadn't thought about the specifics of how to set up a more "revealing" shoot-out. Your suggestion makes complete sense to me. The people who know each player well could bring it to the shoot-out already tuned. This would be far better than the one-size-fits-all approach of the shoot-out that was done. There was no consideration at all given to the possibility that, for instance, a certain plug or cable used in the shoot-out might have been inappropriate for one or more of the players or might even have restricted performance. For instance, the maker of my speakers specifically recommends not using certain kinds of cables with his speakers. If inappropriate cables are used they will make the CDP in that system sound awful and one would then draw the conclusion that the CDP was not very good -- in one or more respects -- in comparison with other players which would be a totally incorrect conclusion. There is also the issue of which power conditioner works best with each player. Alex says his APLs don't need power conditioners. But I read some comments somewhere along the line from someone who said that even his APL was improved by a power conditioner they used with one of the APL models. So even the makers may not know what is best in all cases. I have come across this before with makers of various components. Sorry, I don't remember the details about the conditioner user with the APL in this case -- I'd have to go back and try to trace this information. It's easy to set up a CDP shoot-out that produces a quick "winner" through the process of elimination. It's not so easy to set up a CDP shoot-out that does justice to all the players by showing their potential through set-up that meets the specific needs of each one.
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.
