Interesting comments Zoom. However, the reason I feel that the LCD-3 is creamy/smooth is because of the midrange, not the bass. In fact, there are many professional reviewers who refer to the LCD-3's midrange with these adjectives.
In any event - I'm not new to technically proficient audio equipment, having spent time with other planar magnetic headphones and owning a home theater system featuring Heil motion tweeters (a close relative of planar magnetic drivers). While I agree that it does take some time to acclimatize to new audio gear, fifteen days is more than sufficient for an audiophile that is at or beyond the level of advanced-beginner. The key here is to not continuously A/B reference against your existing setup - but to give the new items time to reveal their nature. A good recommendation is to listen to new gear for three consecutive days before coming to any conclusions or cross-checking against other gear. Certainly I've done that and more.
One thing, you said: "The LCD-3 definitely extracts more detail, so I think it could be veiled". That doesn't really make sense, as the term "veiled" is used to describe a phenomena where something appears to be standing in the way of the audio detail and the listener - as if there were a thin cloth between the headphones and your ears. The 4db drop between 2-3kHz that Tyll from innerfidelity measured can cause this type of experience. I'm not sure if its acceptable to link out to other resources, but if you google for the following title, you can review his notes on the experience of veiled LCD-3's: "Preliminary Investigation of the Audez'e LCD-3 and LCD-2"
I suppose a shorter way of saying all that would be: I prefer the LCD-2.r2 over a veiled pair of LCD-3's.
Still - I live about 5 miles from the RMAF 2013 location, so I'll have another opportunity to listen to the LCD-3's there. I was a little bummed that I didn't see Audeze, Fostex, or WooAudio on this year's participant list. I'll give the 3's another listen at CanJam - but they'd have to sound significantly better than the veiled set I just had in order to come back onto my radar. For now, the TH900's will be my only flagship, unless they just don't have the technical chops of the LCD-2's.
My bad. I meant to say: "The LCD-3 definitely extracts more detail (than the LCD-2), so I think it (your pair) could be veiled"
Ultimately it boils down to your own preference. If you like it, then that's that. If you don't, well, you can look at other options
Regarding the time needed for evaluation I stated was just a personal thing I do. I like to test out a bunch of stuff and repeat it if possible a couple of times over different days with different moods and different energy level. This usually helps drive me to a good baseline performance. Sometimes, something dull on a particular day might seem way too laid back. Although on other days, the same piece can seem quite perfect.
Most people don't wait around anything over two weeks to get a grip on things. You already have experience with high end equipment, so I'm sure you have your method down. Let us know what you think of the LCD-3 the next time you hear them.
