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

Hi Erik, Thank you

Maybe its  time that I utilize a separate dac when I want to listen to my music and still use the Oppo for my surround as I am sure that I wont be losing much by going rca for the left and right channels when going surround. I use my oppo 50% tv movies and 50% 2 channel multi channel music.

Instead of throwing money in to mods maybe I should just go with a new dac? I know there are a lot of wonderful options to be tried and had.

Its just a faint high frequency light sizzling from the tweeter .. more so on the right channel and just audible enough to be a pain in da butt .. I also enjoy late night early morning low level listening as well and its irritating.

Thank you for your input and help I will check out the link as I have read a lot about different mods but now I have to do something about it and hopefully I can fix it myself with some shielding ..

Yes Thank you Tonykay ...

I am thinking of doing this however I am looking at my options to where I ca have a few mods in the process .. maybe a mod on the board itself,  power supply and the caps that Erik suggested at the same time. I rather not spend a lot of money on a full blown mod on the unit at this time.

I am searching for the gentleman that does mods on the oppos and his name escapes me at the moment .. need more coffee or is it a senior moment?  

I'm going to be taking the oppo out of the system and open her up and perhaps get lucky with vacuuming and spraying contact cleaner ... ya right  "good luck on that .. let me know how it works out for you" ..  I guess worth a try for now ..

Thank you guys for your input on this 

Hi Mechans

Yes that's my best guess is the sound board of the Oppo.

Its not that I don't like the quality of the treble .. its an issue of the sizzling tweeter

Yes an interconnect change helped with the periodic sizzle only in that it was not as audible .. but that was going from the (balanced output dac of oppo with my Wireworld Gold Eclipse 7) to changing to the (rca outputs with my DHlabs silver sonic single endeds).  

I want to keep my wireworlds in order to utilize the better balanced dac of the oppo as well as utilizing the balanced circuitry of my Mark Levinson No. 433

Less revealing interconnects will probably make the sizzle inaudible but that's of course what we all don't want .. a less revealing system.  

Yes my mind is working now!

The gentleman that I was thinking of contacting is

Hi Spencer

again .. its not the presentation of the oppo .. it needs repair .. leaking just the slightest sizzle more prominent on the right side.

I certainly did all the recommendations and isolated it to the oppo player .. where exactly in the oppo I don’t know .. again possibly the board ..

That is a good idea as far as trying to isolate the oppos analog board/outs but do not have access to a dac or not sure how I could otherwise ..

Uhm .. ya .. ok .. so I have the oppo out of the system and have taken the hood off her and there really is not much I can do as far as cleaning?

Any suggestions .. I just sprayed the balanced inputs other than that I dont think I really can do anything else with out changing out parts ..

Hi RSV4

Its not my Focals , I already changed them out ..

but not sure if I did in fact try swapping channels .. good idea I will

I just did change the inputs and now I am getting more sizzle on the left channel but oddly there seems to be a bit more sizzle on the other channel now as well ..

I am running 1/2 meter balanced WireWorlds and I am going to try to raise my oppo player up more (my oppo is on the bottom shelf of my Mark Levinson) to take some of the tension off the interconnects .. I wonder if it is that simple? I will try this as welll  

No luck .. there was not much tension on the interconnects anyways ..

I did just sprayed contact cleaner on to the oppo balanced males as well as the female ends of the interconnects .. see what this does ..

Next I will be taking the oppo out of the system and opening her up .. maybe lightly vacuum and contact clean some areas ..  

Hi Nutty

Yes I wanted to use my balanced connects for a complete balanced set up however under my current circumstance with the output noise from the balanced outs of the oppo I am now changing over to the rca out. Luckily I do have two Cardas Audio gold xlr to rca adaptors that I will be using for my left and right dedicated stereo outs of Oppo and I will use my only shorting ring that I have for my center. All the 3 channels will now be running rca via oppo .. I am hoping there will be no noise we shall see ..

Thank you!!   

I cant remember how this shorting ring goes .. I will do a quick google check  
 
 

Oh wow!! Phew .. nice .. no more irritating sizzling tweeters!

Granted I had to by pass the dedicated xlrs on the oppo and now I am running from the dedicated rcas .. been a few months since I heard such beautiful silence! Cant hear any sizzling from listening position and putting my ear to the tweeters only produce the usual hiss and no underlying sizzling!

I guess I will run my oppo/system single ended for now and worry about figuring out / getting the balanced outs on the oppo fixed ..

Still not sure what gives here .. ?

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...
