Thanks for all the great replies! I ended up getting the UW40 and have been listening to them these past few days. Too early to make definitive opinion on them but from Crappy memory they do not sound as good as my old W4's. I had multiple pairs of them so I must have really liked them. I know they are supposed to have the same quantity and quality of drivers under the hood. Maybe I need to burn them in more? Doubt it, but I will do so anyway before final opinion. But just in case, I just RE purchased an old pair of W4 and I will compare them A B side by side with multiple sources including vinyl. Don't hate on me if I like the old ones more. I will definitely update this for anyone who is interested like me. Oh one thing I for sure do not like is the cable and the fact I HAVE TO wrap it around the back of my ears. Its becoming less annoying but I never used to wear all the old ones that way. Also bummed that they didn't come with the old white triple flange tips that they used to. I would cut the last flange off and they would then fit my ears perfectly sealed. Wish I still had the w3 to throw into this comparison as well.
Damn you head fi, Just when I think I am out, you drag me back in! To be continued...
