Review: Esoteric DV-50 with Superclock 3 mod CD Player


Category: Digital

I previously posted a short review in response to what I thought was a large number of DV-50’s for sale on Audiogon. Since that posting, I’ve had many emails asking whether I felt the same now. My answer has always been yes. I’ve also had many questions as to whether I would ever change players, to which I have responded “maybe to the Esoteric X-01”.

Since I have owned a number of high-end players and prefer the sonic signature of the DV-50, the logical step would be to the X-01. That train of thought is based on the reviews of these higher priced Esoteric units. The consensus has been that each is essentially a refined form of the DV-50 with better resolution.

I have also been following the current rage about the modified Denon 3910. I believe many of my emails have to do with the modified Denon being compared to the Esoteric. To date there are at least 5 people and/or companies doing these modifications. Having owned a 3910 for use in my theatre room, the modified unit is quite an accomplishment. The stock Denon is quite simply…dead. Why not modify the Esoteric? Upon researching possible mods for the DV-50, four of the five people doing mods weren’t interested. I was actually told the DV-50 was inferior by one person.

Along comes Douglas Jesse of Reference Mods in Warren, MI. He made several recommendations to possible modifications but the one I opted to try first was the Audiocom Superclock 3. Doug indicated the Superclock 2 had improved almost every unit they ever installed it in. “The Superclock 3 is supposed to be a dramatic improvement“. He stated. This would be his first DV-50 upgrade, so he was also interested in the outcome. At $295 installed, this was a very cost effective attempt at improvement.

The theory behind the Superclock is a reduction in jitter. This is also a complaint that I heard about the Esoteric during my mod research. Supposedly, even the most expensive CD players have inferior jitter reduction circuits (clocks) and the Superclock remedies this. If the high jitter factor in the Esoteric was true, the mod should make as big of a difference as in the cheaper players.

I called Reference Mods this morning to see about picking up the completed unit. Doug said that he had listened on his system and thought there was a dramatic improvement. There was surprise in his voice as to the extent of the change. I was fortunate not to get a speeding ticket on my way to Warren.

The unit is now burning in and is at about 7 hours. The full burn-in period is 200 hours.
In its current state, the improvement is very evident. More musical with better timing, air, transient attack (it was already fast), and definition. Should I dare use the word analog? – It has moved two levels up on the goosebump scale. The only negative thing I have noticed during this break-in is the extended high-end is compressed and changing by the hour. Soundstage width is slightly thinner and also getting better with each CD.

As always, the music used to evaluate my equipment consists of both SACD and Red Book, covering the gamut of musical categories. Specifically this evening, I have evaluated with Joe Sample “The Pecan Tree”, Boston Pops “Summon the Heroes”, Joyce Cooling “This Girls Got To Play”, “The Very Best of Dave Grusin”, Peter Gabriel “ Shaking the Tree”, Bob Baldwin “Standing Tall” and Keb Mo “Keb Mo”.

This modification may put the DV-50 ahead of the X-01 in performance. The mod is that good. Before you sell your Esoteric to get that newest rave unit, I recommend spending the $295.

This response is limited solely to the question of the comparison between the Esoteric X-01 and the stock DV-50, and has no relevance whatsoever to the modification to the DV-50 discussed--that sounds interesting, but I can't address it. The suggestion, however, that this modification will bring the DV-50 closer to the sound of the X-01 may or may not be true, but has to be seen in light of the fact that the DV-50 and X-01 are so different that they could be the products of different manufacturers. I have both sitting side by side in my system (the DV-50 for DVD-A mainly), and both have at least 4-500 hours on them. Put most simply, the X-01 is the most brutally honest source of any kind I have ever heard: a good SACD (the only medium I listen to on it; I use it as a transport for the dCS Purcell DSD and Elgar Plus in redbook) is simply stunning--well beyond the level of the DV-50 in SACD, or anything else I've heard. But on a poor or mediocre SACD (and there are plenty), the X-01 simply tells it like it is; and more than once I didn't want to hear it, gave up and threw the disc into the DV-50, which editorializes a bit--some extra warmth, less revealing. Interestingly, in DVD-A the DV-50 seems more "straight", less warm and cushy, than in CD or SACD. I've pretty much concluded that in digital, unlike analogue, you can't have it all. You pays your money and takes your choice; and then next year you do it all over again. (And yes, I have heard the EMMs and the whokle dCS stack.)
No rebuttal intended. I am always interested in hearing that a mod on a piece of equipment I like has improved it, and that certainly includes the DV-50, and I thought your comments very informative. My only point was that it wasn't necessarily a correct assumption that a particular upgrade to the DV-50 took it in the DIRECTION of the X-01, which sonically is startlingly different in character. As to the other questions you raise, yes, I do think the best single thing the DV-50 does is DVD-A, and in fact I did a direct A-B in my system of the DV-50 against the UX-1 and in DVD-A preferred the DV-50. (Of course I know that other people disagree.) My indicating I mainly listen to redbook through the other units was only to make it clear that my comments were mainly addressed to SACD. My point about analogue was that there seems to be a much greater discrepancy between the way different digital units play back specific digital discs than there is between different analogue rigs on different LPs. And I'm certainly not advocating four digital units where one will do, my system just grew that way out of a few strange coincidences, and provides some interesting comparisons as a result.
