I'm glad to hear on your initial impressions with the LCD 4. For sure it's the full experience on the OG version and I told you it can take any EQ you can throw at it.My LCD4 arrived today. I was testing it on Soul 170HA. Tubes were U52 rectifiers and 5692 RCA redbase. It was utterly amazing. Bass to knock my head off. LCD4 takes EQ like no other headphone i have used. I tried with the 4Z but found it to be pointless. Im actually preferring the LCD4 to the AByss 1266 Phi TC which i never thought i would say. I need a few more days to understand this LOL! LCD4 is an amazing headphone and i have Abyss side by side to AB. I'll come back with my thoughts in a couple of days. What a great night that was.
LCD 4 is just a much more complete listening experience compared to the Abyss.
