If I can be sure that all speakers of the same model produces the exact same hiss with just power connected and volume 0, non-standby mode,     and that the hissing noise sounds noticeably more audible in my house than at the dealer's shop,  is this enough to narrow down the cause of the hiss?
Thanks for your reply!! Which kind of noise is EMI and RF interference on the power?   Is it usually consistent "hissing" sound (not low frequency humming)?  Does it persist with all signal input disconnected and volume turned down to 0?
Thanks again for your replies!!   The noise he's experiencing is "pure hiss", no low frequency hum. It is noticeable even 2 meters or so away in his room.  He says when sleeping with it running, it literally sounds like it's blowing air continuously (until it finally went into standby mode).  Again, he unplugged all signal inputs and turn volume down to 0, leaving only power socket plugged in, and the hiss persisted unchanged.  He even tries to ignore it by turning the...
Does this AC filter help reduce the white noise caused solely by power connection (not by sound source input at all)?
For 1),  the hissing persists exactly the same manner even when all volumes are turned to 0. For 2), that sub came with a 2-prong power cable (no ground).  This is so for most electronics in our country. Can these still be the problem?
 Thanks for your reply!! Could I ask another question? I was trying out the PSB Alpha PS1 + PSB SubSeries 100  at my friend's house. I discovered that the PSB SubSeries 100 (subwoofer) consistently have a hissing sound that can clearly be heard even more than 5 feet away in a quiet room. I think it may be too loud to ignore it as "white noise"...The hissing sound:-does not change at all regardless of the subwoofer volume or the main speaker volume.-persists unchanged even...
For computer audio, could anyone please share inputs on some or all of the following speakers both individually and in comparison with each other, or even comparison with other speakers not listed here if experience allows that: Adam Audio F5 Emotiva Airmotiv4 PSB Alpha PS1 + PSB SubSeries 100 Aktimate Mini+ Paradigm Shift A2   I'm not an audiophile, mainly just want a pretty good lasting speaker. But who knows, maybe I'll turn into an audiophile with a good speaker...
[PSB Alpha PS1 + PSB Sub 100] (2.1) and [Aktimate Mini+] (2.0) cost around the same in my region.   Would it be possible if I could get a detailed comparison between the two packages from audiophiles point of view who has had experience with both? (I'm not an audiophile here, just very curious)   Also, if possible please add in the comparison with Aktimate Micro, Audioengine A2 / A5+   as well.   and the Poll!   Thanks!     EDIT: and I forgot about Paradigm...
