Clearaudio Concept MC cartridge review

I was planning to do a review of the Clearaudio Concept MC cart at some time but when a friend asked specifically, I thought I really should share my experience. I purchased this to replace a defective Audio Technica OC9/III. I based it on two things. One is the claim that this cartridge is a perfect mate to my Concept table. The second was the recommendation of a good friend who is very knowledgeable in the carts and claimed it would “crush” my OC9. As I came to find out, both are true.

The cartridge comes packaged in a pyramid shaped clear Lucite box displaying the cartridge itself. Inside the box, Clearaudio supplies extra screws, a screwdriver and a stylus guard. What was not supplied surprisingly, was any form of documentation. Cartridge specifications and information has to be found externally on the web. Annoying but not a showstopper.

The cart itself is rather boxy looking but has an external casing that appears to be made of the same POM as the turntable platter. The feel is not like plastic but like a fine carbon material. The mounting holes are threaded making the task of mounting to an arm very easy – if you’ve ever struggled with the small nuts and bolt cartridge mounts your will appreciate this.
I mounted the cartridge and ran through the usual setup steps. VTF set to 2.00 (actually 1.99 verified on a digital gram scale vs the table supplied Clearaudio gauge). Azimuth was verified with a mirror and then verified via a test record later. VTA seemed to be spot on (as expected since Clearaudio normally ships these tables with their carts mounted). Rake angle should be 2 degrees tail up from a dead level 90 degrees.

The recommended cart loading is 100ohms however; I did try 121 and 150ohms on a Phonomena II. I found that on my system, the 150ohm loading was quite optimal; at least in initial sessions.

Time to play
I started my test sessions with a standby that tests voicing. Sade’s Smooth operator is a good sample for this. I was immediately captured by the depth of the soundstage, proper width and fine detail. The bass is strong considering the cart loading and the highs beautifully presented. The mid-range was nicely forward and not lost or an afterthought.

Next up, the Moody Blues Days of Future Passed, 45th anniversary remaster. Again, pleasantly surprised as the first notes struck and I could literally feel each detail as the symphony began.

I tried other favorites of different varieties. James Taylor, Elton John, 38 Special. The only way I could describe the feeling was full, rich, detailed. In some ways it reminded me of the warmth of tubes yet the details not lost in the least. It felt “expensive” if that could be quantified.

Compared to the AT OC9/III? The OC9 is a very fine cart with great detail and broad range. But where the Concept MC gives you those same things, it takes two steps forward in terms of soundstage, depth and a musical nature beyond just playing notes. I heard breathing when Sade was performing vocals. James Taylor felt like he was giving me an indoor concert. The symphonic sounds of the Moody Blues were presented as they were recorded and meant to be heard.

In Conclusion
Face it, I am smitten. And for good reason. The advertisement of the match of table and cartridge was 100% accurate and my friend’s assertion it would crush the OC9 (while a bit drastic) was clearly meant to convey what I was soon to learn. The Concept was a clear move “up” in the audio food chain and returned a solid value for the dollar. In fact, due to special pricing, the Concept cartridge cost the same as what I paid for the Audio Technica. After hearing it, I would have paid more (though I am glad I did not have to).

I am also informed, the cartridge takes about 50 hours of play to be broken in and really come into its own. All I can say to that is bring it on.

Various pictures. The Giraffe is optional :D

Thanks for the review Rob. I'm glad it turned out to be surprisingly good and a major step up. It's amazing to me just how good the sound can be, and how it gets even better as you go up the chain, of those same records that have been around for years. Congrats!

I'll have to try mine at 150 and see how things sound.
 
Rob,

Great review. I am glad you are happy. Sounds like a keeper.

Do that..its really system dependent...what I have found is moving UP on the loading gives great highs and detail and keeps the bass crisp. If you move UP on the scale and the highs sound harsh, move down one notch. So if 150 is too bright, fatiguing - then move down to 121. I think 100 is too low and just meets basic standards of a lot of phono stages. You lose a lot of detail.

Let me know !!!
 
BTW..I know its hard to tell from this picture because of the angle I shot it BUT..The stylus tip is dead on the cross hairs and if you sight down the line, the cantilever is exactly parallel . Do this in both spots on Elcoholics alignment gauge and you are dead on. What's the difference between that and the Clearaudio gauge? I will show you.

First understand, there is no such thing as 100% alignment. It is just not physically possible. What is possible is to achieve the best happy medium for all tracks. Baerwald is better at outer tracks and the sacrifice is inner. Stevenson is better at inner but sacrifices outer. But when I say sacrifice, I don't mean bad sound, I just mean less optimal than the other. The Clearaudio single point tries to balance both but none are incorrect.

So how does this work? Picture a groove like a small lane on a road and the dead center of that lane is optimal. On an album, if you are dead center on a groove in the middle of the LP then on track 1, your stylus would be slightly right because of the nature of the expanding curve. Conversely, on the innermost track, you would be toward your left. All of this as facing the table.

Now its okay to be slightly left or slightly right. Picture that lane having say 6 inches on each side for your care. Stay in that tolerance and you are still doing fine. But go too far left or right and you are scraping the guardrail (in this case the groove wall).

This is why you would never want to be DEAD CENTER at the very very start of an LP. Why ? Because by the time you got to the inner tracks, you would be rubbing the wall. This is why two point protractors have two alignment spots at 66mm and 120.89 (baewald). Lofgren uses 70.29mm and 116.60mm. The whole purpose is to get the cart aligned so that from start to finish, it stays well within tolerance of the groove.

But how does aligning the cantilever come into play? Aligning to the cantilever is crucial. If you use the above methods of alignment and your stylus tip is dead on and the cartridge body aligns, your are close. But what if the cantilever has an ever so slight cant to one side? Well, its all about precision on a very small scale. If you do not align the cantilever parallel to the path on the cross hairs, you are slightly off as the diamond tip will be angled slightly. Small scale? Yes. But think about what you are trying to achieve. Precision here determines how it rides the groove and thus, how much musical detail is extracted.

How precise...? well just look at a magnified record groove to see why this is important.

Rob...congrats on the Clearaudio MC! Glad you are liking it. It's fun looking at 500X and 1000X magnification of your LP grooves. Is that with your USB microscope or is it off of the internet? Not sure how much magnification you can get off of a USB microscope so wasn't sure if this was your pics or from the internet. It's weird. You can look at some of these pics and they look like Martian or lunar landscapes. Very cool!

Those are from the internet ...LOL..I wish I could get that kind of picture...The microscope is cool but a little tough to get in position near the table...I will get it though ...

Listening to my table right now and loving it !!!
 
Rob... Congratulations on the new cartridge. Talk to Jeff about a Furutech phono cable. We couldn't believe the sound difference (for the better) with that cable!!!
