Oppo 105D high frequencey sizzling issue anyone help me suggesting a mod that i can do or?

Ya No .. so I have had the Oppo 105D since April 2014 and have enjoyed it and never had an issue .. until lately ..

I am getting a high frequency sizzling at the tweeters via the dedicated balanced 2 channel outs.

With less of a revealing interconnect one can not hear it at my listening distance of 10 ft but I do want to keep my WireWorlds Gold Eclipse 7s .. as they are so open and revealing ..

I know that its the Oppo as I have isolated and changed out speakers, cables, interconnects, power cords and by passed my power conditioner as well and all leads point to the noisy audio board.

So I contacted Oppo and it would be $119 for them to put in a new board .. very reasonable I think .. however they cant guarantee me that it will solve my issue as they cant duplicate my exact set up and interconnects..

with the above stated .. maybe I should look into a modification as we all know there is a lot of mods that can be and are done with the oppo 105.

Maybe I try things myself? Thinking of trying to emi rfi shielding the power transformer, power supply cover, transport lid 
 Any suggestions and real world experience that you may have are greatly appreciated.

Thank you for your time .

I had a similar experience with an Oppo 95, but it was a somewhat strong sibilance that presented itself in the vocals, whenever an "s" was pronounced. It turned out the amp and pre were quite a bright combination that was having a cumulative effect on the highs.  I only used the RCA's, and it was present only on certain brighter sounding tracks.

I’ll never go back to that brand again.

Hi 213running

Ya thats cool that you were able to tame the sibilance with better matching components .. my issue of course has nothing to do with sibilance

But I am happy to say that I am now listening to a sizzle free sound ..

I am running through the dedicated rca instead of the xlrs as where the problem occurs .. hopefully the rcas will remain sizzle free for years to come as I do like the Oppo. In defense to Oppo .. it is almost 3 years old and I will have to estimate that we use it atleast 4 hours a day 6 days a week. So we are looking at a conservative estimate of  4,000 to 5,000 hours on the dedicated balanced outs...

Good news that you were able to find a solution, I've heard really good things about the 105.  I've still got a 103 that serves me well about 3 years in.
