Re: [SlimDevices: Radio] Can two SBRadios sound differently?

This reinforces the suspicion that the hardware was changed for the worse in a later revision. altruizine's Profile: http://forums.slimdevices.com/member.php?userid=57433 View this thread: http://forums.slimdevices.com/showthread.php?t=96609 ___ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio
Re: [SlimDevices: Radio] Can two SBRadios sound differently?
Finally I did another comparison, this time both Radios plugged in.
Other conditions as before: same firmware, same LMS settings ('smart
gain', 'both channels'), side-by-side comparison with positions swapped,
sync'd playing, volume level manually set to the same number, both on
wifi and both equipped with battery.
Again, a freeware SPL meter app - this time, Logitech's UE SPL on iPod
touch ;-) - did not measure a difference between the two.
But again, I could clearly hear a difference, both when playing syncd at
the same time, but also evident when one was muted and switched back
on.
So my conclusion is that my new Radio with HW revision 7 doesn't sound
as good as the older one with revision 4. :-(

If the second one is the result of 3 full hardware revisions, then I would think it's easily possible for there to be a difference in loudness between the two at a given numeric setting.

That's what begin to think, but more in line with different drivers that have a different sound or some other part difference. My idea with the battery compartment ,the plastic chassi is not very thick and the battery cavity large vas the speaker box so it would create different acoustics and the battery could dampen things a bit . But I don't have two radios, never tried .

Although I know that it's certainly possible to get a sound difference by using different parts, I assumed that Logitech tries to keep the sound characteristics the same. reinholdk's Profile: http://forums.slimdevices.com/member.php?userid=36070 View this thread: http://forums.slimdevices.com/showthread.php?t=96609 ___ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio

I measured the two radios with a free SPL meter app for Android and it showed -- no difference. But I definitely *hear* a difference between the two. And I'm not the only one.

Hmm ok there is also the issue of frequency response and distortion and overtones from the drivers, if they changed a driver it migth not be the same tonality . Battery or without battery btw ? Wonde if they sound different when the battery compartment is stuffed or empty ?

Re: [SlimDevices: Radio] Can two SBRadios sound differently?
I'm using the new one w battery, so I compared both running on battery. I'll try both plugged in. Do you think it could even make a difference if the battery compartment is empty or not? reinholdk's Profile: http://forums.slimdevices.com/member.php?userid=36070 View this thread: http://forums.slimdevices.com/showthread.php?t=96609 ___ Radio mailing list Radio@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/radio

I did a side-by-side comparison, playing them sync'd with both set to the same volume manually. Both run the same firmware version, of course, and both were connected via wifi with my LMS. The old one seems to sound a bit louder and thus more dominant and clearer. If I set both volumes to 60, for example, I have to reduce that of the old one to nearly 50 to get the impression that both are playing at the same volume. I also switched the player positions to make sure that this has no influence. From the Settings menu I found that the hardware revision of the old one is '4' while the new one is '7'. Don't know what Logitech changed, but I wouldn't expect that one could hear a difference between different versions. Is this just my imagination (or my ears) or is this reality, and if it's the latter, why? Can be a difference , is it brand new does had many hours of playing ,the speaker driver may need some run in time to be at it's best (about the only thing in audio that may need burn in ) . But as they are of different hardware revisions ,who knows :-/ maybe they found a cheaper part . Do you have an SPL meter ?
