I’m using single ended headphones with balanced adaptor , i have no problem with hum on single ended at all .

That is exactly your problem, and I kept saying this over, and over, and over.....and no one is taking it seriously enough

Stop using the damn Single Ended headphones and use an adapter into Balanced 4.4mm......those people who made these adapters have no clues whatsoever......***you are essentially creating a short from L to R, and this will DAMAGE YOUR PLAYER.

You read those in bold and cap correctly

Exactly.

You can NEVER go from a balanced output via any form of converter to a single ended headphone.

You can use a balanced headphone via an adaptor from the single ended output.

Good catch. @giovvanie Using a properly wired balanced headphone will eliminate shorting the (-)'s of the 2 channels together. This will probably solve your hum issue. You will still have to deal with the rest, but that may be more tolerable once the hum is gone.

Thats your actual problem, using BAL to SE headphones... that is a No-go.. my HPs are balanced capable and included a balanced cable thu i do balance to balance.

Either you'll need new balanced capable headphones or rewire internally your headphones, these shown are Sonys 2014 lineup, mdr-z7 and xba-z5, even the older xba-h3 are balanced capable and some older HPs can be but you must make sure these have all the way down to the jack 4 wires.

The cables shown for the IEMs, Z5 are stock ones with an adapter made by a head-fier for me. and the other are the MDR-Z1R stock 4.4mm cable

Oh dear ... Unfortunately nobody have told me that before i make a purchase ... I’m hope i did no damage to device since i’ve got this cable from this morning and used perhaps 5/6 hours ...

What is a possibility i have damaged my player allready ? I have used this adaptor for 5/6 hours ..

I would expect that Sony have put something in there to protect the player against this, but you really wont know until you plug in a fully balanced headphone

Yeah i will place order for balanced cable , if i did damage on balanced output should have no sound or some kind distortions ? , what could happen there in worse scenario ? Sound still went through headphones yet .

Yes if there was any damage it should be a short circuit and then I would expect there to be no sound on the balanced so chances are that there is no damage

Thanks a lot for you and for all who help me find out what cause that issue , probably ( i hope so ) i have saved my 1k DAP

Yeah, I'm considering this one too. So what about that buttons feeling? I had Miter case for DX200 and the buttonmarks were too soft to feel them with confident. Matter of softer leather I suppose.

Leather there is soft, but i feel buttons normaly. Maybe one day I will but some felt disks from inside with glue. Maybe...

I experienced some pop while I was listening to sad files.

But only with a specific combination of cable and earphones, it could also be that there I didn’t import them correctly from the sacd.

Changing cable or using different iems the pop disappear.

I would test the player with different songs, I never had the problem listing to aiff that I imported from cds.

It looks for me that key words there is "changing cable". I am very suspicious that there could be wrong wiring.

 

[Matrix Petka]

I talked with my friend, who is making cables - possible that there was short on ground cable (not so dangerous as short on between signal wires). And it could sound as humming. Sony 4,mm jack have very specific wiring. 5 contacts, only 4 of them active.
Golden rule - there is no adapter from balanced to single ended. All headphones MUST be rewired for for balanced use. 4 wires!
