Should you pull the trigger you say? You do realise where you´re asking this question don´t you? If not, look below, the artist was inspired by the average follower of this thread:
I can´t comment on the Willsound line, but I really like the FAAEAL Snow Lotus 2.0, I listened with nothing else for four days in a row when I first got them which is a first for me, although deep bass is not their forte. Silly question, but have you tried foam rolling with the MK3? It certainly won´t break the bank and might get you closer to your desired sound, if you tell us what kind of signature you prefer (warm, neutral, analytical etc) maybe more people can chime in and help.
