Two week later I've bought a new Gold and try to do the configuration the same way as stereo mix with Spark App ; without any success ; so I've thought that my newer
Gold was already Dos2 enabled.
So I decided to try to migrate to dos 2 and do a stereo pairing.
My two Gold setup appear in the Devialet App and decided to continue the setup; after selecting the stereo pair Left/Right and location ; the app said that my left Gold phantom
(the older one previously setup in Spark) need update. After the update and some confirming sounds my pair was ready to listen my playlist from my external Tidal App!
The next morning in standby mode ,I was surprise to notice, by touching both Phantom rear end ; that the left one (older one) was warmer than the right one (nearly no eat detectable).
I went into the Devialet App and select the left icon to hear the clicking confirming the selected Gold Phantom did the same with the right one and the clicking sound was a bit louder on the left phantom ...bizarre.
Checking into the Devialet App I noticed that the left Phantom (the one warmer) was running on 2.8.5 but my newer one (right/colder) was running on 2.8.0
Try to reset everything and restart the setup but the devialet App said that my update are ok ; no need to update ; Why two Gold Phantom not running the same update version?
Also running a wifi sniffer test on my router show this designation: Phantom M37P000874U06 192.168.12.232 Gemicon Technology,inc. (older one) and my new one: GoldPhantom M30P002754U10 192.168.12.243 Liteon Technology Corporation !
Why Phantom vs Gold Phantom designation and the WIFI technology are not the same ; is that why one Phantom drain more energy because it does not use the same wifi technology??
Could I get sound imbalance in stereo pair because my two speakers are not made alike with the same wifi circuitry ?
Could anyone help me ??
Hi @rogmay,
Your serial numbers indicate that both were made this year only a few weeks apart and that your left speaker, the one you refer to as the "older" one, is actually the newer of the two (that is the one running 2.8.5 iiuc). So although they are clearly from different production runs and seem to be using wifi chipsets from different manufacturers this fails to explain both the difference in behaviour and the discrepancy in firmware versions. I suspect that the firmware update on your right hand unit has failed for reasons unknown and that it is actually the difference in firmware that is the cause of the differing behaviour and not any minor differences in hardware. Could you try splitting the stereo pair in the app and reconfiguring with the 2.8.0 speaker as the left-hand speaker, then seeing if it wants to update firmware? Apparently the Left is the "master" of a stereo pair.
Also, like you I think it is a little bit strange that one speaker is reporting itself as a Gold but not the other. Could just be human error but just to check could you http into each of your Phantoms (just enter the IP addresses one at a time in your browser address bar and press return) and check the "about" info? What does each speaker report for "model" and "version"?
