I have been used ZX300 with Andromeda and Alo litz 4.4mm balance cable. It doesn’t have hiss, sound good.
Now I upgrade to WM1Z. I disappointed because on WM1Z 4.4mm balance port show a lot of background noise. It hurts my ear when I listened for a while. On 3.5mm unbalance port WM1Z it’s less hiss. Is it normally?
How can I fix? Maybe This paring doesn’t match. I think, should I try WM1A next? Anyone using WM1A with Andromeda 4.4mm balance, Are there any hiss?
Or I should go back ZX300 which one perfect match Andromeda on 4.4mm balance port?
Umm..I use many combinations of IEMs (including K10 Encore, a pretty efficient IEM) and multiple upgraded cables with my 1z and I've never heard 'hissing' either from the balanced or single-ended jack. How old is your 1z? Maybe burn-in will help (?).
Well it is strange? I have the Encore too, and no hissing, though I only use it single ended. Everything else 4.4m.
Though everyone has a different hearing potential. I’m not sure I remember anyone ever describing hissing with any IEM with the 1A or 1Z? I wonder what it would be? Though it seems 3.5mm single ended is acceptable for you? So you use an adapter or different 4.4mm cable?
Are you using firmware 3.01?
You know there are high and low gain settings......right?
I would say keep trying other IEMs and cables, as it could have something wrong with the cable. I would bet it’s the cable. If not the cable? Hmmm?
Also take note, the 4.4mm capacitors are unstable until burn-in.
I hear hissing all time, when I plug in cable and display shows up hissing start. While I listen songs although I turn volume down until zero hissing still shows.

You should try a different cable after 200 hours of burn in. This is extremely critical, but I did notice volume fluctuations in the early burn in hours. Sony’s explanation is the capacitors need 200 hours of burn in to stabilize.

There could be some issue with your IEMs too. Not CA, but I’ve read of wrongly wired IEMs. Just try cable first. Different IEMs next. Then finally try a different player. You could have dog hearing; it’s a blessing really!

I already burn in 530 hours. And I try to use MMCX IER-M9 stock 4.4mm balance cable with my andromeda. It's still hissing but lesser that Alo litz cable.

It’s less due to the possible change in cable material properties. Different cables have different capacitance. I would again try a different 1Z, and a different set of IEMs. Your player could be defective, but stuff like that is rare. My money is on your hearing being incredibly accurate, but it’s strange that you become fatigued? Still you need to change out IEMs and 1Z players at this point.
Only because your Andromeda is a fairly often used IEM, which we would have heard about.
Hi Mosika, I don't have WM1Z, but I don't hear any hissing or background noise on my WM1A with 4.4mm balanced ALO Reference 8 (copper) cable Andromeda, high gain setting , volume at 30-35. 200-hour burn-in.
ALO Litz cable is silver plated copper could be 'brigher' than pure copper , if you have copper cable, please try . Also to check your mmcx connection if they are loose ?

You have already put 530 hours on the player and you mentioned earlier that you didn't hear hissing when you use the IER-M9. I wonder how many hours you used the Andro during that burn-in process. In fact, I also wonder if you bought your 1z brand new.

Since you bought your 1z player brand new, I think you should talk to the dealer/seller. Ask them if you can try another 1z and see if you have the same problem. If not, they should help you get a replacement as that can imply that your player is faulty. Good luck.
The ZX1 also outputs 15mW+15mW, runs Android and has about half the battery time of the ZX2, but also uses a smaller battery due to the much slimmer chasis (Japanese users had calculated it to be under 1000mAH), while the ZX2 gets double the battery life with an industry person confirming that its battery capacity is double that of the ZX1 at 1880mAh - and it gets roughly double that of the running time of the ZX1. So to get double the battery life such that the device meets the requirement of CEO Kaz's "must last a cross Atlantic flight on one charge", they put a bigger battery of double capacity in there and that's about it, is all pretty straight forward maths/engineering. Of course Sony's not going to tell you "well we didn't increase the power output of the headphone out to meet our CEO's request" because that would be extremely bad PR, but again if you look at the spec it's straight forward maths/engineering.
Now that we know the WM1A/Z outputs 4 times as much power on SE in a body that is roughly the same as the ZX2 - battery tech certainly hasn't improved that much since the release of the ZX2 and we are already able to see the internal of the WM1A/Z already from all the photos and they haven't hollowed out all the components to put in the biggest battery in there, so the reduced power drain must be attributed to the things that did change even in light of the massive increase of power output. Which means it's either the removal of the WiFi radio (unlikely - test conditions almost never turns on WiFi for DAPs) or the OS (very likely, since you can't turn off the OS). So by logical deduction it's going to be the OS, there's almost no other way to get around this conclusion.
Plus it's no secret that Android is a battery hog in the IT world, and pretty much all the DAPs which runs on Android on the market now struggles with more than 10hrs playback time. So it's pretty obvious what is to blame here.
