I got the elephant URHQ so that you don't have to. Here's my thoughts:
-Seven Nation Army is super clean, too clean. As a producer friend of mine once said about a Nirvana remaster, "This shit isn't supposed to sound clean!"
-There's a bit more fuzz on the rest thankfully.
-It's flat. It sounds quite good. Real solid separation of instruments, more than I thought possible based on how the band recorded a lot of their material.
-I got it cause it was showing a low stock alert, and it's one of my all time fave albums and fomo kicked in.
Now....is it worth it...
It's unlikely. I don't hear a $125 increase in quality. I don't own a McIntosh or a Mofi deck. Maybe if you've invested a bunch in your equipment there's something there, I don't know! I just know that if you've invested $2000 or less that you probably don't need this version.
I do not anticipate that I will buy a UHQR again. FOMO be gone!
