Although I have the excuse that I had also swapped to 4gb SD cards for the configurations when I switched from the beta, suggesting the latter, not the firmware, had made the difference. Or maybe it suggests I've plain gone bonkers, either way, I have absolutely no plans for any more firmware swaps for a very long time!(27-Jul-2015, 20:35)I Confused Wrote: Some observations, the ihm_0800.hex file included in the beta version as sent to me by Devialet is also dated 25/6/2015 (the same as Guillaume's copy), secondly, ihm_0800.hex is by far the largest file in the set. RE: New firmware 8.1.3 - Rufus McDufus - 27-Jul-2015 If there's no SQ-related stuff in this module then the only difference I can see is that the memory map would look slightly different and I can't see how that would affect sound quality. It is very strange. I have to admit I have the pre-release version and it clearly sounds better to me. The release version sounds no different to 8.1.2.

My money's on cache alignment (Only kidding...or am I?) RE: New firmware 8.1.3 - Confused - 27-Jul-2015 In Devialet's own words........ Do a short press on Tone button. The software information will be displayed. The "IHM" will be the version (i.e: 7.1.1) RE: New firmware 8.1.3 - Rufus McDufus - 27-Jul-2015 That's interesting Confused - this is the page where they claim the IHM version is the software version. https://help.devialet.com/hc/en-us/articles/203402221-How-to-upgrade-the-internal-firmware-of-your-Devialet Now on the 8.1.3 pre-release (and largely for all recent firmwares I've seen the first screen shows 'SW 8.1.3' or whatever version it is. IHM is on the next screen along with other module versions. On the 8.1.3 pre-release the IHM version is 8.1.2, not 8.1.3.

Well possibly! Also I don't know whether it's different when FPGAs are involved, having never dealt with them before. There's a whole lot more complexity there.

Anyone know?) This is TRUE! Official 8.1.3 with updated 0800 file sounds flat and without ,,body" comparing with previous version sended to some persons by Devialet. RE: New firmware 8.1.3 - Vivialet - 28-Jul-2015 8.1.3 is fixing some problems with certain SAM profiles. 8.1.2 was giving a fat and boomy bass with some profiles. So if you like fat and boomy bass then maybe 8.1.3 now sound flat. You should always mention if you compare SQ with or without SAM. For my speakers SAM set to 0% is still fat and boomy, it increases the bass around 70hz by about 7db. I can use this bug to fill some gaps but I have to use the jRiver EQ to get rid of excessive peaks. The result is now very good, but without EQ SAM would be unusable for me. btw, no change in this behaviour between 8.1.2 and 8.1.3. And the profile for my speakers has been updated for 8.1.2 already which introduces this bass boost. The old profile was doing nearly nothing and more degrading SQ. |
