New beta firmware available for M-DAC - display dimming!
Dominik of Lake West has just posted a beta version (a.04) of the M-DAC firmware that includes the ability to exclude all but 2 filter profiles when scrolling through them, absolute phase invert; input phase lock banwidth settings; display dimming after 20" or display dimming to "L A K E . W E S T" after 20".
It's very easy to update - available from PFM (post #561). This is provided by the designer & not audiolab. The original firmware is also available so can be rolled back. I have updated mine about 6 times over the last few months without a hitch. This beta is likely to be very close to the final update. You obviously use at your own risk.
Unfortunately, it's not well documented! There's also been 2 versions since my post with susposedly subtly different SQ, the last version enabling you to switch between the 2 (A.06). There have been at least 6 firmware updates since launch! John Westlake is very busy designing the B-DAC, M-AMP, M-PAX & at his own admission, isn't too good at documentation!
All I can say is that the updating process on Windows works flawlessly but finding earlier versions might be hard to roll back to. Until someone documents all these changes on John's behalf, it maybe a good idea to hold fire until a final version is available but don't bother looking to audiolab for updates - they don't even have a link to the bitperfect test files the last time I looked. Some versions have had minor bugs but none have caused problems.
Since launch:
Absolute phase invert
SPDIF PLL bandwidth options that have helped those using the Logitech SB having lock problems (Jitter rejection Option)
A workaround for a bug in the DAC chipset that the manufacturer isn't addressing
Mute function pausing playback via USB
Display dimming - either dims the display or dims then display then shows " L A K E . W E S T " after 20"
Powerup to last selected input or chosen input (bug to be resolved)
Universal remote control codes to allow direct access to inputs without having to scroll
The ability to reduce filter options to just 2 during scrolling
(I think that's it!)
Future possible options may include input renaming but may loose absolute phase invert but am not certain about this
The M-PAX is supposedly going to include a beefed-up PSU for the M-DAC, a basic FM tuner & analogue input(s) but not sure if means an ADC or analogue output. The M-AMP is going to use modified class A with a future class D design (JW either owns some novel class D patents himself or has been the inventer - no sure which). I'm also not sure what projects will be marketed by JW as Lake West or by Creek. He has also upgraded the SQ on certain customer units sent to him in the Czech Repulic & intends to continue to do so! On one hand, even John has lost count of the options he's made available & on the other, continues to support a product well beyond the call of duty!
Are you currently running the A0.6 firmware ?
The threads on PFM are a bit long winded and its difficult to find anything on there, I did find a copy of the original version though (V0.9) so might give the upgrade ago. Someone needs to create a sticky on the threads with links to the various firmware versions.
Yes, I'm running A0.6 at the moment but I'm deaf in one ear (wax) so cannot comment on SQ. You are not the 1st to mention the difficulty of finding updates so have just posted a request to consolidate all this stuff into a sticky.
One other question, I am running a 64-bit version of windows 7, I think I read somewhere that you can't update the firmware from a 64-bit system is that true or can you run it in XP compatibility mode ?

That's not an issue. Some people have had problems running Windows VM on a MAC.
New version for both mac & Windows
I need a bit of guidance with the bit perfect test.
I have downloaded the test waves, loaded them into mediamonkey and replayed them into the m-dac which is in the bitperfect test. The display just shows 'scanning for match'
What does that mean, the instructions say it should say pass of fail.
Bump
No one tried the bitperfect test then ????????
I'm just about to plug in, update, then run the test. Will let you know how I get on.
Still can't get anywhere with the bit perfect test, anyone else had any joy with it especially when using media monkey ?
Completely forgot to post back on this!
I did the test through iTunes, USB direct from my Mac Mini, worked fine. It brought up "scanning for match" momentarily, but then switched to the test.
Have a try with iTunes, see if it does the same as what's happening with Media Monkey.
I didn't realise iTunes did bit perfect playback, anyway, tried it and the same results just sits there 'scanning for match'. The only device I can get to give a pass test is the Sonos.
I tried all different settings in windows 7 and nada, can't get it to work, don't know what else to try.
I said the test worked fine, not that iTunes passed 
Touche, indeed you didn't lol.
Regardless of that mine still didn't start the test. I assume it must be a windows setting, don't know what else there is though.

Is there a complete list of changes anywhere for this firmware update and have you found it stable ?
