No I don't, as I am enjoying the fruits of your labour enormously.
Follow Ups:
1 version ago I made 3 optimisation changes, feedback received has pointed to one of these affecting the sound adversely, so have rebuilt the 3 versions with the best sounding option ie use MFC in a static library.Have rationalised the download folder to just hold the latest versions and moved everything else to an archive folder.
have also uploaded a readme filehttps://rapidshare.com/#users|459800...a4b6194c|11541
The use of MFC setting is completely counter intuitive as MQn doesn't use MFC, my thinking is that there are some windows libraries that are used and they sound better when imported as part of the static MFC library than when shared windows libraries are used.
Hopefully, that is the last of the changes as it now sounds pretty sweet.
cheers

The one test I didn't do was current version which uses intel libraries vs current version built with VS2012 libraries, hard to decide which one is better, the intel ones seem to have better definition and the VS2012 sounds sweeter. Have posted mqn.exev2.2VS2012 for comparison against v2.2.
Have uploaded instructions on how to integrate MQn with foobar2000
mqnfoobar.txt and mqnfoobar.bmp
Found a magic setting, another veil has been removed from the sound. The instrument and voice articulation is now simply stunning, it's the first time I've been able to pick any instrument and follow it throughout the song/track.

Unfortunately v1/2/3.3 had an issue in that the new setting introduced a very unsettling type of digital frequency which made it hard to listen to after a while, so had to remove that setting as couldn't find a satisfactory working setting.All is not lost though, as I found 2 more optimisations in the render loop (these have really tidied up the sound, should have spotted them before) and retested A_memcpy against memcpy and CopyMemory (A_memcpy still comes out top) and retested MFC static vs shared windows library setting and retested the vs2012 libraries vs intel c++ libraries and retested profile guided optimisation vs non pgo.
So all in all this should be the final release, the sound is now very together ie coherent, no real weaknesses, the digital sound of 1/2/3.3 has gone, plenty air, bass, detail, can follow instruments through the music and also place them better than previous versions ie it's a gorgeous sound and the better your system the better it should sound, though it sounds pretty good through headphones plugged into a laptop.

now I just need to see if I can control it remotely via foobar2000 and my samsung note 10.1, convenience of digital music with MQn sound quality, does it get any better ?

I have just release vx.6 which switches off the desktop window manager's use of MMCSS leading to a dramatic improvement in the amount of detail obtained and a fantastic 3d sound stage.
https://rapidshare.com/#users|45980080|0ae609ce616a35c8de7ac5fda4b6194c|11541
Just released MQn version x.14
download from
https://rapidshare.com/#users|45980080|0ae609ce616a35c8de7ac5fda4b6194c|11541
version x.14 needs the MMCSS and DWM services to be disabled for best sound quality, there are instructions in the MQnMMCSSDisable Readme.txt file (requires a small registry edit)
Have also uploaded a method of playing flac files with MQn using sox to decode them to wav before playback start, there are instructions in the readme file in the MQnFlac.zip
version x.14 is a big step up from v x.6
1. I had implemented MMCSS the wrong way round so that it was affecting the sound quality, I experimented with the recommended way and finally came to the realisation that MMCSS was bad for sound quality, so v x.14 doesn't use MMCSS and it is recommended that MMCSS is disabled. MMCSS is there so that cpu intensive media apps are not affected by other system loads, MQn is not cpu intensive and is a constant load so doesn't need another process (MMCSS) switching threads and priorities in and out for what is a non existent problem (MMCSS is designed for a heavy periodic cpu load and then a period of no load).
2. I had set the priority of MQn too high so that it was affecting critical system processes and sound quality, v x.14 priority has been lowered to the best setting for sound quality.
3. Intel have updated their c++ libraries, the new ones provide quite a step up in sound quality.
the future - plan to have pause and track skip back/forward and a more comprehensive decode ability. The decoding is done in the MQn.bat file so if anyone wants to have a go at setting it up to handle other formats then feel free.
oops, version 1.14 used copymemory for 16/44.1 instead of A_memcpy, have uploaded a corrected version and moved the old one to the archive in case anyone wants to compare.
versions 2.14 and 3.14 were not affected
https://rapidshare.com/#users|45980080|0ae609ce616a35c8de7ac5fda4b6194c|11541
version 22 - dialed back some of the optimisations that made the sound worse and added some newly discovered ones as my understanding improved.
Removed profile guided optimisation, removed prefer fast code, removed mfc static library, added MMCSS back in, aligned memory to cache, added string pooling, /vms /vmb switches
best version yet - detailed, dynamic, analogue like.
https://rapidshare.com/#users|45980080|0ae609ce616a35c8de7ac5fda4b6194c|11541
requires mmcss to be enabled and running
also recommend setting mmcss pro audio background only setting to True
regedit
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Pro Audio
change Background Only to True
uploaded version 26, the final and best version for sound quality as verified by my testers.
Phew, don't think I tried all the thousands of combinations of build settings, but it felt like it, after a while you get a feeling for what effect a certain setting is going to have.
So, optimising the code is only half the story - getting the best sounding optimisation settings has proven to be harder to work out and I'm not giving them away.
no digital sound, fantastic detail and dynamics, timing and rhythm of a high end turntable, all in all an outrageously enjoyable sound
next release will introduce stop/pause/skip
needs mmcss enabled and set to start automatically
advise setting the background only setting of mmcss pro audio setting to True
regedit
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Multimedia\SystemProfile\Tasks\Pro Audio
change Background Only to True
mqn v.27 uploaded to solve slight lack of bass
https://rapidshare.com/#users|45980080|0ae609ce616a35c8de7ac5fda4b6194c|11541
have uploaded a version which allows control of mqn - version mqn.exev2.50 control
space bar to pause/resume, less than sign to skip track back, greater than sign to skip track forward, M to skip 5 seconds back and / to skip 5 seconds forward, it is not case sensitive.
Unfortunately there is a slight hardening of the sound due to the extra thread, but it shows what can be done. Am looking at other ways so that the sound is not affected.
Also uploaded a much improved version of mqn - version x.47, this version has the buffer set to 8192 for all resolutions and also stops the console and associated input/output/output streams. The impact on the sound quality is pretty breathtaking, perhaps one of the biggest improvements so far.
need to use mqnstop.bat to stop mqn version x.47 as it is no longer associated with the console, so just download mqnstop.batbak and rename it to mqnstop.bat and create a shortcut on the desktop.

I'm going to make a bold statement and say this is the best (free) windows player out there. If you have heard anything as sweet or detailed then please let me know, because I haven't.
It has taken a while and I have been guilty of hyperbole with previous versions, but this is the real deal, absolutely stunning.
I have posted a 2.50 and a 2.46 atom control version, but the sq is inferior, but it's there anyway.
https://rapidshare.com/#users|45980080|0ae609ce616a35c8de7ac5fda4b6194c|11541
new version, quite a major upgrade in sound quality, think this is the final version in terms of SQ.
to quote one tester who came from mpdpup
"I am thoroughly enjoying 2.79 I can tell you. So far ahead of anything
I have ever heard from my system."
"2.79 is just breathtaking. I could listen to 2.79 all night and it just encourages one to turn up the
volume (always a good sign). Astonishing detail which i could never have
believed Red Book could contain."
am finalising a version that allows control of MQn, it acts very much like lifting the needle on a turntable, ie the user makes a change and returns the player to best quality, other players use other threads or are constantly checking for user input, both of which affect the SQ.it uses a mqncontrol.exe as well as mqn.exe
while mqn is playing music, the user can press a key and a separate console appears where the user can pause, fast forward\rewind and skip tracks forward/back.
what happens is that mqncontrol.exe changes the page protection of the mqn sound buffer to no access, this way the render loop doesn't need to check for user input and mqn doesn't need a separate thread to be constantly running.
mqn immediately throws an exception as it cannot read the sound buffer
mqn has an exception filter which is called, this starts a menu thread and resets the page protection so the music can keep playing
the menu thread opens a new console and waits for user input
the user makes changes and presses x to exit the menu console/thread
the menu thread is stopped
mqn is returned to highest SQ state.
will be released next week
needless to say, no other player does it this way, yet.

Think v 79 is a bit too balanced towards the bass, here is a version that is better balanced.

Hi SBGK:
I get File no found on the link!!!!
I need your latest effort, please correct.
Best regards
Juan
try this onethe latest version is v80
Edits: 05/30/13
yup, think it's a keeper, listening to Johny Cash, quite hard for a player to get the depth of voice, sense of space, tone of instruments, bass and timing correct - MQnvx.5 does it with ease. It's amazing what it is retrieving from 16/44.1. I think you can tell when something falls into place, it just sounds right.
The important thing is does it make you tap your foot tap in time to the music.
uploaded a mqn.exev2.1 (usb devices)which uses intel specific files. The result is a slightly improved sound, less lean sounding. The old v2.0 is still there for comparison.

I tried using reclock and shanpcaudio reclock enhancements, initially an improvement, but soon gave me a headache, prefer the natural sound of MQn.
Interestingly he is selling the his high end player for £180, anyone tried it ? There is a free version of lesser quality, both integrated with foobar2000.

He has an article further down the page where he mentions the intel c++ redistributable files
