Review: Linn Schulte Modified CD12 CD Player


Category: Digital

I just got my Linn CD12 back from being upgraded by David Schulte of The Upgrade Company and thought I would quickly share my experience. Right out of the box, without any burn-in time, I am simply ecstatic with the outcome. All aspects of the CD12’s performance have been significantly improved, and I mean significantly. In fact, I have aborted my plan to buy a new SOTA CD Redbook player.

I have to admit I was a major skeptic about this whole “upgrade thing”. I was concerned that the process might improve some aspects of performance at the sacrifice of others. Or worse yet, that I would get the unit back and it wouldn’t work. But after reading about other Audiogoners experience, particularly Clement Perry’s recent experience having his Reimyo upgraded, I decided to take the plunge.

The Linn CD12 is a CD Redbook only player and was introduced in 1999. It is no longer in production although Linn has a stockpile of parts to service their installed base indefinitely. Mine is the latest 24 bit model and I have had it for over three years. On a scale of “literal versus lyrical”, the CD12 is strongly biased in the lyrical direction and for many years was a reference in CD Redbook playback. The CD12 has brought me countless hours of sonic bliss.

However, in recent years new players have emerged that matched much of the CD12’s musicality while improving upon it in terms of resolution and dynamics. In my opinion, the CD12 has always been a touch laid back in those areas. And so many audiophiles have moved on to newer players, particularly those that wanted CD Redbook and SACD/DVD-A capability in one unit. Being at that cross roads myself, I began an intensive review of all the current reference level SOTA CD Redbook players. As I have a Linn Unidisk v1.1 that I use for SACD/DVD-A my focus was only on CD Redbook which comprises the majority of my CD collection anyway.

Well, as we all know, there is no shortage of great choices out there to chose from at all price points and that’s great for us as consumers. But the new SOTA units I auditioned, while improving on the CD12 in some areas, were just not enough of a “slam dunk” to get me to switch. So, being at a bit of an impasse, I ultimately decided to take the “upgrade plunge”.

While I know there are many excellent, well regarded equipment upgraders in the market, I decided to go with David Schulte of The Upgrade Company because: (1) he had lots of very positive references, (2) he had successfully upgraded other high end CD players including Clement Perry’s Reimyo and (3) he had upgraded a CD12 previously and had a clear plan of what needed to be done.

David’s approach is not to modify the unit’s original circuit designs, but rather to upgrade selected components that offer superior sonic performance versus the stock components. Further, he has other tricks up his sleeve to deal with the deleterious effects of resonance/vibration and EMI/RFI. But, he rightly keeps all of that to himself, as I would if I were him as that is his intellectual property and competitive advantage.

David was an absolute pleasure to deal with. As I wanted to minimize downtime, he called me when he was ready to operate on my unit. I overnighted the CD12 to him and he got to work. He explained the spectrum of upgrades he offers and the pricing and I ultimately decided for the “full monty” wanting to push the CD12’s performance as far forward as possible. I found David to be a no-nonsense guy. He knows from 20+ years experience what is worth doing and what isn’t and I never felt he was trying to push fluff on me. We talked several times by phone and exchanged several e-mails throughout the process to let me know how it was going. At certain stages of the modifications he would listen to the player to see how its performance was changing.

So today I got the unit back, plugged it in and let her rip. After I got my chin up off the floor, wiped the big grin off my face and listened for about an hour I got on the phone to let him now how pleased I was. As I mentioned at the outset, every aspect of performance has been improved immensely. The inherent musicality of the CD12 is fully intact, but the noise floor has been lowered significantly which is allowing new detail to emerge that was previously masked; resolution throughout the range has increased dramatically (particularly at the low end) and micro and macro dynamics have improved immensely as well. And David tells me that the Blackgate capacitors (which were part of the upgrade) improve with burn-in, so performance should only get better from here.

One of the things he told me is that most of his modified CD Redbook players outperform SACD recordings. I said okay when he told me that, but didn't really believe it. Well, I just listened to Patricia Barber's Modern Cool which I have on SACD and Redbook. And, well, he was right, the Redbook version sounds better. I'm not saying that will be the case on ALL recordings, but it was a revelation for me that Redbook could sound that good. In fact, the CD12 performance has now reached a point where vinyl will probably go by the way side for me. I'm sure SOTA vinyl is still better than what I have now, but what I have is sufficiently good at this point that I will skip the hassle of vinyl.

Well, I’m now a converted skeptic and next week I’m sending David my Runco DLP processor (his modifications are equally effective on video circuitry I’m told) and Unidisk v1.1 universal player for the upgrade treatment.

Bottom line, upgrading components is probably not for everyone, but based on my experience the price/performance ratio of upgrading versus buying new is compelling, particularly in the area of digital.

Happy Listening,

John, what do you think you could possibly buy down the road that would be better than an upgraded DV50s that has been worked on by either APL or the Upgrade Company. To my knowledge from other people that have had there Esoteric's done by Schulte tell me that the stock DV50s or DV50 sounded thin and tinny compared to the upgraded unit. It was not just a slight improvement either. I have a suggestion, call Schulte and ask him to send you the little JVC dvd player he has to compare to your DV50. Maybe he would do it if you gave him a security fee. I have one here at my house but it does not have the same upgrades as the one he has now. It is still a great performer though for a ten pound unit. He would probably be afraid that you would sell the Esoteric and keep the JVC. But seriously do not sell the DV50, you want the same upgrades that went into the Linn cd12 and I garauntee you that you would not have to search for another unit. Schulte will give you that garauntee too.

You are kidding, right? No-brainer, not down the road, vinyl today.

Seriously though, with HD-DVD and Blu-Ray technology now being released the DVD side of the DV-50s is already outdated.
Also, as I'm sure that you are aware, it's all about system synergy, not one piece of equipment works well in all systems. The DV-50s is hardly tinny sounding, but it is more resolving than my previous BAT VK-D5SE w/ Super-Pak. I would believe it could sound thin in the wrong system. Fortunately for me, my speakers are warm and lush (Verity Audio Parsifal Encore's), so the DV-50s helps the speed/resolution factor, but doesn't sound thin in my system. Maybe with leaner speakers such as Audio Physics/Theil/Wilson it would, who knows? It certainly isn't a problem in my system though.

One more thought, it is a tad premature to keep mentioning The Upgrade Company neck and neck with APL. Maybe one day they will be viewed in the same light, but not yet. As far as mod reputations go, TUC still isn't in the ballpark of Exemplar/Modwright/APL or even TRL. They are more competative with the likes of RAM (Reference Audio Modifications) as far as being the new kids on the block with no major reviews. Coincidently, these are the two companies (RAM & TUC) that seem to have the most experience modding the DV-50s. That's not necessarily a negative, but let's not get carried away.

Just because I'm a fan of Ridge Street Audio Designs cables does not mean that the company is the equal of Kimber. I perceive RSAD to be a better sound/$$$, but not necessarily a better value. What do I mean by that? I can buy RSAD cables for less than half the price of the Kimber Select on the used market and they sound a tad better in my system. However, when I re-sold the Kimber I didn't lose a penny. I lost about 50% of my investment when reselling my RSAD cables.

If that view bothers you I understand. Most modders don't like to look at re-sale, and they shouldn't. If you sink the money into a mod, you should plan on keeping the equipment, as it is not a good investment. If you enjoy it, great, keep it. I've been on both sides of the fence in my 28 years in the hobby. I've been the original owner/modder (The Mod Squad/EAD), and I've bought modified units second hand for crazy low prices (got a GNSC modded phono stage once for 23 cents on the dollar). For someone who changes equipment as often as I do, paying full price for a mod is not an easy thing to justify. Especially now, with all I've learned about tweaking with cables, power cords, Walker Extreme SST, Audio Points, etc.

So while I am still considering it, $1700 + shipping ($2790 for the RAM full boat) is still a good chunk of change to me. Especially if I can't recover any of it in a year due to the advent of HD-DVD. Resale on non-HD DVD universal players may well be in the toilet a year from now, who knows? Point is, these are things I have to consider. I wouldn't be playing at this level in this hobby w/o choosing wisely.

One final note, no digital gear I've heard can compete with my vinyl setup sonically. Yes, digital can be made to sound better, and it certainly is more convenient, but I gave up on ultra high end digital ($20K seperates) when I re-discovered vinyl several years ago. Perfect sound forever? I don't think so.

Cheers,
John
John, you are right regarding the dvd side to the story. I did not realize you had vinyl. What a great opportunity for someone to upgrade that DV50s to compare to your vinyl setup. I also see your point in sinking too much into the upgrade, now that I know more about your system.
I think it would be an intersting phone conversation between you and Schulte, seeing how both of you have about the same amount of time in this hobby. He started doing upgrades about 24 years ago and decided to offer his services much further.
What is the reason for upgrading if you have vinyl? Have you modded units yourself in the past? Just wondering what the owner/modder meant.
What is the reason for upgrading if you have vinyl?

Well, I do still listen to digital. As I said earlier, I haven't heard digital that approaches the sound of my vinyl, however, vinyl does require more attention. Cleaning and changing the LP or 45 can get you moving every 8-25 minutes. When I have the time, and for critical listening I always choose vinyl. However, there are many times when I listen to music that I'm busy multi-tasking (reading, working, etc) and the longer play time of digital is convenient. Also there are some recordings that I cannot find on vinyl. So I do listen to digital quite a bit, maybe even over 50% of the time.

I chose the DV-50S over a Exemplar 3910, both sound unheard, in the process of downsizing/simplifying my system. I'm selling off my cd players/dvd player and just going with one digital source. I've already sold my top BAT seperates for a Jeff Rowland integrated amp. I've only had the DV-50s for a week, and I'm not unhappy with the sound. I chose it over the Exemplar 3910 because the modded seller was not as flexible in his negotiations. Perhaps that's why he has had it listed for a couple of months now. I can't blame him, he will be taking a bigger hit finacially than the DV-50s seller, I know, I've been there. Modded units are not easy to sell w/o losing your shirt.

Have you modded units yourself in the past? Just wondering what the owner/modder meant.

I've only modified speakers, not electronics. I've done some minor tweaking with electronics, chassis damping, Bybee additions, but no circuit modifications. What I meant by owner/modder is the original person who pays to have the modifications performed. I had The Mod Squad (pre McCormack) and EAD (they started as modders too) upgrade digital players for me. Digital upgraditis is not new, I had these done about 15 years ago and lost around 70% of my modification investment dollars when I sold the units.
I felt the mods helped quite a bit, but since then I've taken to purchasing units after someone else has paid for the mods. Thereby someone else has taken the initial and most costly hit instead of me.

I'm not doubting modifications, I've heard first hand their success many times. I am considering paying for mods again, but I'm in no hurry. I do think the stock DV-50s represents a good value for the dollar, especially used.

Is it perfect? No, but what is? Could it be improved? Probably, but at what cost? Does The Upgrade Company intrigue me? Yes. Does the lack of information concern me? Yes. To be honest, I'm not used to paying money for unknown changes. I try new things, but I usually either have some idea of the technology, or have tried it before I bought it. The cloak of secrecy is not unusual, I have tried Shakti stones, Walker Extreme SST, Bybees, and many more quasi-secret items, some I've even purchased. TUC's money back guarantee may make it worth trying. I'll have to do some more homework.

I don't feel comfortable responding online anymore, as I really didn't mean to hijack David's Linn modified CD12 review and turn it into a modification debate. My apologies to you David. Once again, thank you for a terrific review, and congratulations on your newfound happiness.

John
John, you did not hijack the thread at all. It is about a modified unit and what Schulte has done for someone again. And I am just standing behind his findings. What is amazing is how good the unit sounds to David before the full break in period. If you look at another thread under Denon mods regarding "Pardales" Denon 9000 you basically get another view of what Schulte can accomplish after a full break in period. What I see in other threads is the evolution of the modding business and believe me the debates will probably continue, which is probably good for the business. It would be interesting to see how far back they go on audiogon. In closing, who would have thought you could take a 15 or 20k player and make it so much better?
