Listened to LZ l and ll. I thought LZ l sounded fantastic, crisp, clear, tight, dead quiet backgrounds, very impressive.
ll sounded a little muffled to my ears, Plants vocals sometimes a bit more in the background, a little bass heavy, somehow not as cohesive sounding as LZ l. After hearing how great LZ l sounded I was a bit disappointed but all in all it's still pretty good. I'll give it another go tomorrow but overall so far so good.
