I feel the first one has a little more sparkle to it. I think I actually prefer it, but I think it's the one without. Though I felt the mix was a bit phasey sounding (something weird going on stereo wise???) and a little too indistinct and mushy already for me to really ear it properly. Don't know.. All we know it is early days in the testing process so I'll wait longer before I decide on it yet!
