>Why would you worry about motor noise if you're using Etys? Trust me, my old MZ-R91 did indeed have a motor noise every 45sec that penetrated even the Etys and it was annoying enough if I listened to any kind of peaceful music at lower volume.. >... can an NH900 even power Etys? I own the ER4-P's, and they can be powered with ease by *every* decent portable thing.. :smile: (as far as I know they were created very much with this in target..)

Ok, thanx again for the clear answer! :smile:

Thanx to everyone for the answers! :smile: I now trust that the NH900 doesn't produce a noticeable hiss, but about the motor noise I would still like to ask more precisely.. KJ_Palmer wrote: "Motor noise, as Latexxx says is there, I don't find it loud or frequent enough to be annoying though..." -About how freguent is it, once in a minute..? KJ_Palmer, if you would listen to some very peaceful music through your HD-25 headphones, volume at 10, MD-unit about 1 meter away.. Would you hear the motor noise if you tried to listen for it..? Thankx, Teddy

I intend to buy a Hi-MD unit, and the MZ-NH900 seems to be the 1 for me, as I see it now. Here are a couple of things I would be glad to get answers to before making my decision whether to buy or not: 1. Does the MZ-NH900 produce a background-“hizz” in the sound when it is turned on, while playing music or paused..? And now I do NOT mean bass, but I mean the same kind of hizz that so many cd-/mp3-/md-portables nowadays have (because of a cheap amp/audio-out..?). I remember that my old MZ-R91 (back then the flagship of Sony’s md-line..) did have a totally clear sound, but a few other cheaper models did not; they produced a background-hizz.. This is NOT ok for me, as I listen to very “delicate” music/sounds at times, and I have Etymotic plugs that don’t hide *anything*.. 2. Does the MZ-NH900 have ANY motor noise while playing? If any, then how disturbing is it..? (I know this is a very subjective question, but I’d be totally content to get some very subjective answers! :smile: ) My old MZ-R91 had a motor noise that came on every half minute or so (to save battery life..) and it was loud enough to be VERY disturbing to me when I listened to “quieter tones”..! I know Sharp MD-units haven’t had motor noise for ages, but Sony can’t seem to figure out the mechanics, it seems.. :wacky: -Someplace I read, however, that also Sony’s models have become a little quieter now, but what is the truth..? Thanx! -Teddy

-1 thing I know is that Apple doesn't care to give out the S/N:Ratio of the iPods.. ..and in my experience the iPod (3rd gen. 40gb..) did have a noticeable hizz/noise when I turned the volume up a bit, and no matter if I listened to AAC, MP3 or WAV.. Earplugs used: Etymotic ER4-P. One device that seemed to have good enough S/N:Ratio was my old MZ-R91, there was no hizz/noise in the sound of that device. I have owned a MZ-R700 too, and that one clearly was below desirable S/N:Ratio. It might be I have very sensitive ears but in that case I'm not the only one out there because I've read several times that ANY sound-device with a S/N:Ratio below 95db will produce a disturbing hizz to sensitive ears (AND phones/plugs!). Most MP3-players (as well as even "high-end" portable cd-players ) have a S/N:Ratio of 90db. For me it is of no joy to have a powerful amp in the portable device if the noise/hizz is powered up too.. As far as I know, the only HDD-player out there to overfill my and many others criteria is newer players from Creative, they all have a S/N:Ratio of 98db... Now that's what I call sound-QUALITY! :smile: (other players of sound-quality are Cowon's iAudio-players, but those are not HDD..)
