Thank you. Mine are 2005 / 2006 vintage. They still may not have gotten much break in, though. They look mint. I just tried them out with my Headroom Ultra Desktop amp. Interesting that with the S cable, they are less efficient than my Denon D7000's. Low gain with the Denon's, medium gain with the Ety's. They are pretty close as ER4P's, which seems reasonable, 25 ohm Denon's, 37? ohm ER4p's. I only got a couple of minutes with them. The diferences weren't dramatic, and I'm not sure which I like better yet. If the ER4P's do feature boosted bass, I might like that better. We'll see I guess.
As to the "boosted" bass, I listened to "Temptation" by Diana Krall. It's one of my evaluation songs. The string bass sounded distinctly like strumming rubber bands, vs. quite deep and rich with my Denon's. Very tight and detailed, but just lacking a bit of body. Yes, they are polar opposites, yes, the Denon's are fun, rich, deep, and not all that accurate. That said, I do love them, and they are not that far from the sound of good $4K speakers throughout their range, save for the slightly sucked out mids.
I'm looking forward to getting to know the Ety's, and to see if they stay with me. Interestingly, these are the first tri-flanges that seem comfortable, at least in the short run.
As to the Apuresound cable - dang! My Ety's are used. The cable is like 140% of the cost of the Ety's! Anyone want to sell me a used one?
