There should be a hash noise when you first start the unit up from the screen being off and no music playing, then press play, (check again) and then the noise dissipates to a very fine hiss, barely noticeable on my IEM's, it starts off pretty loud tho, so you should hear it.
I find it hard to believe the amps start hiss is completely gone now. Has anyone else got a new zx2 from the new batch that can confirm this?
Just tried it again to test, but it is completely hiss free.
In fact, it is completely silent in the background. This is what I did for the test:
Stop the music player. Fast forward to next song (so that it will start from a fresh song later). Switch off the screen by pressing power button.
Here, I tried both methods to start the music:
- press the play button directly
- Switch on the screen, press play button on the LCD screen
Both ways played songs without any hiss or noise. In fact, it is the most quiet player that I have tried.
I can try to switch off the power fully, let it cool down and try again. Started using the ZX2 few days back. Brought home and charged fully, and then turn on to test - could not hear any hiss or starting noise at all. Was pleasantly surprised as was expecting some noise since I have been reading this forum before buying my ZX2.
Tried on both XBA-Z5 and JH16pro.
Could not be my hearing, as I am finding it pretty loud just listening at 15-20% loudness.
BTW, it is perfect match for ZX2 and XBA-Z5 - this is just using SE connection, and it sounded really good. ZX2 not burned in yet, only played max 50hours.
