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.

The LP is flat & boring & used as a calming medicine - Geoch -

I guess you never heard a Benz LP mounted on a good arm and on a good turntable.

Yes Curio....there are a number of posters who don't know what they are writing about, yet take the position of experts. You have to take the good with the bad and understand that the internet allows everyone to display their stupidity, and intellect.

Concerning the Benz LP argument, let's don't forget that cables really can make a big difference due to changes in capacitance, etc.

So at least 3 people have mentioned the phono stage, both here, on the telephone, and my dealer via email. (did talk to Bill BTW, he is trying to help) I will sub in my Dynavector phone stage but can someone point me to an explanation of how a phono stage can cause sibilance and/or mistracking?

Thanks

So I have about 38 hours on it using 40min/LP as a multiplier.

Put the Dynavector P75 MkII in place of the GCPH. Surprisingly it sounds pretty good with the Kleos. Has a peak someplace around 1-2k which makes it sometimes sound a bit lowfi but this could be the cable. Had Hero balanced from the GCPH to the NAD M3 integrated. The P75 has bass more like the GCPH when used with the Kleos.

Anyway, let the P75 warmup and the sibilance is still there. Playing an original pressing of Court & Spark. Man the Kleos can separate the voices.

Heater's on 70.

BTW, using 100ohms as I was on the GCPH.

Hi Robob,

I unfortunately don't have the solution to your problem, but I've struggled with sibilance distortion quite a bit as well, and I have a long thread about it. Maybe some food for thought in it somewhere?
