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.

Tvad, I agree. This is about a close to an interesting test as I can conceive. It just shows how difficult it would be were reviewers to do such a shoot-out.

One additional question for me is whether those participating would sell their unit to buy the winner.

I once participated in a shootout very much like this but comparing preamps. Among the six or seven preamps including those manufactured by some of the participants, the Bozak had the highest rating! I for one, never thought to buy one. I did scratch my head about these results, however.
IMO, Just two tracks (and both classical at that) are not enough to claim any digital pairing superior over the other. You need varied kind of music. well recorded acoustic music is preferable of course.
PLUS few hours between five units are also not enough to be conclusive. Aural memory ususally is also short lived and you gotta go back and refresh pairing many number of times to get more data samples.
The panel also need to have breaks in between to get back bearings/tonal reference. You get kind of tone deaf after a while.
I am not saying APL may not be clean winner or others a close second but to be scientifically correct simply more data samples is needed. IMHO.

Tbg - The APL unit with its volume control and line input capabilities could replace my current digital player, preamp, 2 PCs and IC. However, I would still need at least another $10k to afford either of the top two players if I were to sell all this gear. This is too expensive for me.

I quickly put the same tracks in my system as soon as I could after the event to get a feel for how my set up fared against what I heard just 30-40 minutes earlier.

It did not take long, about two bars of music on either track, to notice the refinement in transparency and the smooth resolving ability the top three players had compared to my digital player. This was particularly evident in the mid-high to HF range. I have a maxed out Philips SACD1000 that was modded by APL. I did not start out looking for an APL player. In fact I originally wanted the Opus 21 or the Exemplar 3910. The deal on the Philips was too good to pass up so I got it instead. The SACD1000 is quite capable and is competitive in image focus, soundstaging ability, tonal balance, with an engaging combination of mid and midbass articulation and body, and bass extension and dynamics. Unfortunately it just does not have mid-high to HF performance that the top three units had in our blind sessions.

As to my take on the comparisons, the DCS had a more lively/dynamic presentation than either the Meitner or the APL, which is probably why I liked it better than the Meitner in the quieter choral piece. My vote changed for the Meitner when the orchestral track was played. Despite a less deep soundstage compared to the DCS, its smoothness and more natural presentation of instruments won me over. [This is really where the latest wersion of the Meitner really shines compared to what I remember of the previous version.] The DCS and APL presented a better delineated and deeper soundstage than the Meitner. The Meitner and especially the APL were better at presenting more believable natural tonal and harmonic characteristics of voices and instruments.

So wish me luck on my quest to find a more affordable digital player that can come close enough to the DCS, Meitner and APL.
