I had G68R on loan prior to getting my own 861V6 and I did play around with Trifield setting, width and depth made quite a bit of difference but eventually I prefer the default setting. So, when I have my 861V6 I never bothered with changing the Trifield parameters especially when the sound was so good with the 861V6. Having seen the the last post from VirusKiller above, I decided to give the width another try and this time I could not sense any change of sound with the width changes. Will give it a try again with more materials when I have the time tonight. What is the latest firmware for 861V6? Could not see any firmware update for 861V6 on M website.
