Just went back to the stock M1060, after purchasing a new one (selling the other one – again). And I must say, after having grown into the M1060 for about a month -- which seems almost obligatory before making any comments or giving any clear opinions -- I really don’t find the modding as impactful as is claimed in here. The Vegan pads certainly improve upon the headset in both comfort and sound (reducing the sibilance). But it does neither of these two things so much that it's required to do the mod. The stock pads already give very good comfort, and the issue with sibilance isn’t there like it was when I first got the M1060s. Maybe it’s a result of me getting used to the headphones…I don’t know. Stock pads also offer better isolation and a bit more pronounced bass.
The reason I bring this up is because a lot of issues arose with pad rolling my first two m1060s. When you take out the stock pads, sometimes the filter comes with it, sometimes it doesn’t – this is uncertainty can't be changed or brought under control. If it doesn’t come off with the stock pads, you’re basically screwed in terms of warranty. Generally, the stock felt coming off, adhesive looking “used” or parts of the Vegan pads getting on the adhesive in the process, will make it pretty easy for Monoprice to see that pad rolling has happened, and will make it easier for them to void your warranty on basis of it. And I can assure you that as a newcomer you will end up taking on and off the pads more than once, as the Vegan pads themselves are so large that they float over (forcing you to carefully adjust so that everything is fitted perfectly).
The M1060s are fantastic “flagship killer” headphones as they are out of the box. I recommend the paper towel/coffe filter mod as the only necessary one; if you really care about keeping the vital 5 year warranty, as well as not spending an excessive amount (~$80) on Audeze pads. Even more so when taking the shoddy build quality of the headband, which I’m almost positive will not outlive the warranty period, into consideration. After a month of use, the screws are already screeching by the slighest movement.
EDIT: My comment above is based on my experience with the Vegan Leather-Free pads. I don't know how the Vegan Leather, Dekoni Sheepskin or any other pads are on the M1060.
