Lo del ingles…
Hi all,
Just wanted to put in my experience.
I bought my Z680 set on New Year's eve and have been messing around with it for the past 2 days. I was initially quite worried about the hissing issue until I was given a demo. While the hissing was audible, it is only noticeable when I put my head within 1 foot of the satellites. It is acceptable to me at those levels.
Since installing the set at home, I did notice that the bass sounded somewhat loose/boomy. In the Dungeons of Moria scene in The Fellowship of the Ring, the speakers produced admirable depth. It is a great improvement to my Inspire 5300 set. We do not get much quality speakers (short of home theater systems) here in Malaysia, however, so I do not have much exposure to speakers in the States.
FYI, I bought the ones with the old specs as the new ones were not available.
Happy New Year!
Osea, que el siseo se oia pero solo a menos de un pie de distamcia, que le molan y esta contento de haber sutituido unos Inspire 5300 con estos logitech.
I just wanted to echo awpk's sentiments. I was pretty dang close to being scared away from these speakers completely based on what I've read. Well today I went down to CompUSA to hear them for myself. After listening to them for about 10 minutes, I remembered that I wanted to verify the hiss I had read so much about. That right there says something. If I hadn't read about it, I probably would have never noticed. When I first turned the volume all the way down I didn't hear a hiss at all and I thought Logitech must have fixed it completely. I moved my head to within a foot and, sure enough, there was an ever-so-slight hissing sound. My reaction was "That's IT?!! That's what all the fuss is about?!". Logitech MUST have improved this, because the amount of hiss I heard could in no way warrant the outcry I've heard since these came out (IMO, of course). Either that, or some people are INCREDIBLY anal. Not that there's anything wrong with that...
Bottom line, if you're looking for a good set of 5.1 speakers, don't discount these based on what you read online! Hear them for yourself, then if the hiss is too much, don't get them. I'm glad I listen to them before I bought something else, or else I would have been pretty pissed.
And no, I'm not affiliated in any way with Logitech. FWIW, there was a set of Klipsch PM's right next to the 680's and as awesome as the 680's sound, I like the sound of them a tad bit better. Of course, I had no access to the software EQ or anything...
Que fue a escuchar unos,y al rato de estar oyendolos se acordó que tenia que comprobar lo del siseo...
:rolleyes: asi que ni se habia dado ni cuenta de ello. Dice que los que se quejaban tanto del siseo son "INCREDIBLE anal" 
que se traduce por algo asi como "increiblemente pijoteros", que os pensabais XDD. Pues eso, que DPM y que se los compró, que es imposible que la gente se quejara tanto del siseo con lo bajo que se oia, asi que supone que Logitech debe de haber arreglado el problema del dicho ruido de fondo.
Hey, I just wanted to comment on the hiss.
When I first connected my speakers with analog, the hiss way very unnoticable. When I connected them through a coax digital, the hiss got alittle louder. You people, like the guy said, are WAY too anal. How can a slight hiss bother you that much? If they come out with a fix for it, then I will return them, but if not, these are an awesome set of speakers. I'm not worrying about a very slight hiss. It doesnt even look like logitech is going to fix the hiss anytime soon, based on emails and calls I made to best buy.
Que con conexion analogica el siseo casi inaudible, que con las opticas un poco peor, pero sigue sin ser pa tanto, que los que se quejan son "WAY too anal":D que no significa "camino hacia el ano", sino "demasiado exigentes" y que si en un futuro Logitech sacara un arreglillo pa este defectillo, los devolveria para que se lo arreglasen, pero que de momento se los queda y a gozar...
We are not in any way being too picky about the hiss. You must understand me. I bought the 680s a few weeks back and returned them for the 560s. I had them connected with the analog cables to my SB Audigy. The hiss was VERY LOUD. I am not exaggerating. I was at least 3.5 feet from each speaker and the hiss was exceptionally clear. In fact, anywhere in my room the only thing I could hear as they were idle was hiss hiss hiss. Even through quiet passages of music there was much hiss. You obviously have a different set of speakers than I had, believe me, because if you had heard mine you would have returned them, too. Logitech must have goofed with their first line of 680s, and you now have the second, fixed variety.
All speakers that I have encountered will hiss at some audible level. Usually you start to hear it from about a foot or less, just as you said the case was with your system. This is also true for my 560s; they hiss at a very low level. BUT the 680s tried by myself and every other 'anal' person that posted here hiss way too loud to be acceptable. No other system hisses like that. You could hear them hiss from five feet when the volume on the control pod was set all the way down!
Do not make such a reckless delcaration based on so little information: you have only heard your speakers, not everyone else's.
Uno diciendo que de anal nada, que a el le sonaban los logitech que no oia nada mas que siseos por todos laos y que seria que estaban jodidos porque tambien tenia unos z-560 y sonaba poco el siseo,como deberia de ser...
Great news! Apparently Logitech has started replacing the control pod with an updated one. I can't confirm any of this, but I found this on another forum:
"When you have the old controlpod (version 1.03), call Logitech and ask them for the new one. You can check the version by doing:To check the ROM version, put the unit in standby, and then hold the input and settings buttons together for 5 seconds. The ROM version will briefly appear on the LCD."
Aqui dicen que si Logitech esta ampaquetando con los ultimos z-680 otro controlpod (el cacharrito ampli/deco), que es donde se supone que se estaban generando los problemas.
