I edited 15 internal metronome audio samples a little bit; applied careful hipass filter, removed slow attack or pure silence from many of the sounds. I also removed DC offset and improved fade outs.  Some of the files had up to 3 milliseconds silence or weak attack before the actual hit which may lead you to play out of time even if you play accurately.
Changes are subtle and you may not hear any difference if not doing A/B tests.

Installing
 
1. Open Metronome folder in Explorer. In SONAR Platinum it's:  %appdata%\Cakewalk\SONAR Platinum\Metronome
2. Make backup of the folder in case you want to revert back to factory sounds.
3. Extract archive to Metronome folder. 
 
 
 

Cool. Thanks, Panu. Good thinking.

Thanks, will give them a try.

Thanks, Panu.

Thanks!!

Does anyone know if the Sonar installer will overwrite these files every time? If it does you might want to keep the archive near by so you can reinstall them after every monthly update.
 
They are better than the stock ones, thanks for making them available.

We're gonna find that out pretty soon. I zipped original Metronome folder before replacing the sounds and put Panu's archive in the same folder, so I can easily restore original or polished sounds if need be.

Thanks for sharing your opinion. Will try 'em tonight.
 

Even if updates do not reset the metronome folder, it would be a good idea to retain a copy. Should you ever need to  perform fully re-personalize SONAR, the files will get overwritten at that time.

Many thanks Panu and also to Steve Cook and Soundwise.

Thanks for these.
