Kleos Sibilance


Hello Folks,

I posted this in a Delos thread but I thought I'd better start it's own thread.

I have a new Kleos in a JMW 9 Signature on a Scoutmaster. I am getting sibilance on vocals beyond what I have heard with either a Shelter 501 II or a VPI Ortofon on the same table. My dealer put the Kleos on the wand I had the VPI cart on. I have gone to 1.8g and did not solve it and I have checked the alignment. I brought the rear of the arm down as well. It may be less pronounced but it is still there. Otherwise the Kleos is quite nice. It has 3 or 4 hours on it now. I do not hear misstracking on high level passages, just sibilance and sometimes some grunge on male vocals. It is not on all vocals but it is fairly common.

Again, trying to be fair, trying to be unbiased, after reading much, of not all of this thread, I still personally haven't came to any solid conclusions.

My thoughts are, is, or was it truly the JMW Arm to blame, or could it possibly be something else?

I have no financial interest, or gain, to come here to say the JMW Arm is crap, or is it the Lyra Kleos at fault?

Or that maybe the real truth lies somewhere in the middle, that neither are/were at fault, and the playback issues were caused by something else?

As I had hoped Mr J Carr would've participated, as i know he's highly knowledgeable, but I can think back, and remember some words he once said, and I'd like to roughly quote some of his own comments from the far past.

I remember Mr Carr once commenting about Cartridge design, in regards to the many design principals persued, and implemented.

That he once commented about the Benz Cartridges as an example, of being a versatile Cartridge, but with that versatility came compromises in the design.

Compromises, that may have allowed the design to be usable in a variety of conditions (meaning various Tonearms I took this), but perhaps as well a compromise in the optimum performace that could've been achieved.

I don't at all question what he had said, and will not question the truths to those statements, as the man no doubt has forgotten more than I'll ever know about an MC Cartridge.

But with those statements, I perhaps can read between the lines, and understand that he may have also said in a round about way, that with his designs, and Cartridges, that they have been optimized per the "Lyra way", that his Cartridges, to be fully realized may take a little more attention-detail to set up, that his designs won't "candy coat" a presentation-recording, that they will lay bare the "truth", and sometimes in those instances, playback can be heavenly stellar, or laid bare with all it's flaws, and shorcomings. And that also, his designs may be a little bit more particular in the Tonearm they will be paired with.

Others, that as well may share similar revealing traits as these Lyras, could be the top tier ZYX, and I can recall people like Doug D making mention, that to extract the best playback from a Cartridge like the ZYX UNIverse, that any old Tonearm wasn't going to cut it.

Is that then a flaw of the Arm itself, or of the Cartridge? Or actually of neither? Just a incompatible mismatch? Mark
That could be it, a mismatch, but a VPI dealer knowing what table I had sold me a cartridge that has no business being on that arm. I am just speaking about my situation. I have read that others have had problems with their cartridges even after being set up by VPI. I would think they would know how to align cartridges. I believe one of those instances is mentioned in this thread. Maybe it was a defective cartridges, or should I say cartridges. Who knows.
Update. I recently realigned my cartridge. I do not believe it. My cartridge is tracking beautifully now. It is one of those, what happened? I have heard better, but it is certainly listenable right now. I think the biggest thing that I did was adjusting the VTA and azimuth. More the VTA though. It seems as though the Benz I have is very sensitive to VTA and only being off slightly is all the difference. I am very excited! Even though it is somewhat difficult to set up, it took me about a year, it is possible. I cannot believe it. Sounds great through the whole side, very little inner groove distortion and tracking error, big improvement. There is still some sibilance on some tracks, So Long So Wrong last track side two, but I believe this to be a recording glitch and just very demanding to track. Maybe a better cartridge or a MM cartridge could do a better job but I am not touching any of the settings. It seem together, the JMW 9 and Benz H2 are not very forgiving in setup.
Good for Tzh21y!

I am the OP and no amount of adjusting has solved my issue. As I mentioned, putting weight on the headshell improved things significantly.

Over last weekend I removed about 1 gram of the Blu-tack (imitation brand) and reset VTF/VTA. This resulted in more lively sound and somewhat underdamped sound. And the sibilance increased somewhat.

Yesterday I removed the Kleos and send it to Sota so they can install it in a SME 309 for my upcoming Star refurb. I put the wand with the Shelter 501 II back on the JMW 9 Signature and readjusted VTF, etc. Real difference. Not as fast, lighter and undistinguished bass, and generally lower quality sound. The Shelter is pretty good in some areas, it does retrieve a fair amount of detail and has a clarity that my VPI/Dynavector 20xH cannot match. Of course I bought the Shelter when they were under 1K$.

Y'all have some fun,
Robert
