This is a bit disappointing to hear since I just placed an order for a Z7m2. But good to know.Been using the Z7 for a couple days now on first listen there's an immediate lack of detail compared to Z1R, shimmer are still there, it just feels more blunted up high, certainly doesn't reach up as high, bass has less punch doesn't reach as deep, the Bass is defjnitely the one characteristic of the Z1R that jumps at you in first listen to the end man surprisingly, I kinda missed it's bass more than treble.
But then I listened to it the morning after it and all feels normal again.
Yeah, honestly, if you're not a critical listener and just enjoy the music they definitely aren't that different, its just whether you want to get more or not.
I think we all want more but if it weren't for rent and this urge to eat that kennerton flagship would be on my head right now.
