  Review: Linn Schulte Modified CD12 CD Player
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,

Thanks. Yeah, I have to admit my system is sounding really good with this upgrade of my Linn CD12.

His website can be found at upgradecompany.com His e-mail address is MrHiEndAudio@aol.com. He does modifications to just about every type of audio and video component. If you have an interest just ping him via e-mail.

Regards,
David

John, I think you will find that David will share much of what he proposes to do, just not everything in full detail. Good luck.

04-21-06   How much was your upgrade?   Tvad

04-21-06: Earflappin
$999 was the price for the standard upgrade Tvad, but the full boat I went for totaled out to $1700 not including the return shipping. I think I paid $16,000 for the CD12 new, so the upgrade cost was about 10% of that.

I believe I've seen you post over on the APL board. Maybe I'w wrong about that. In any case I am eagerly awaiting the chance to listen to an APL NWO-1 or NWO-2 to compare it to my modded CD12.

John, as I posted earlier in this thread, David will tell you the majority of the components that he upgrades. There are really only a couple of things that he does that he holds tight to the vest. Good luck. BTW, I think it's good to be a strong skeptic in this hobby as there are so many products and tweaks out there that various people and reviewers hype that don't work. I know I have blown a fair penny on that crap over the years. David does offer a money back guarantee for that reason.

Okay, I've now got about 160 hours of continuous burn-in time on my modded CD12. Through the first 140 hours or so the improvements were very gradual and subtle. Everything opening up more and more type of thing. Within the past 24 hours, however, there has been a step change improvement, so much so that I just called David Schulte to share it with him. The low end resolution has really improved and then the soundstage overall has opened up to a degree that I would never have thought possible with digital. My biggest problem now is dragging myself out of my listening room.

Happy Listening.

Jpl208, that's what I'm doing now is running the CD12 24x7 to break it in as fast as possible. While the rate of improvement has slowed dramatically when I play specific songs that I am super familiar with I can periodically detect some improvements that are still occuring, most notably at the low end. I'm so happy now that any further improvements are just the icing on the cake anyway.

Happy Listening.
