While I'm discussing the LCD-i4, I thought I'd bring up a discussion we had about it on the Head-Fi.org Facebook Group. Fellow Head-Fi'er
@bmichels was asking about the merits of the LCD-i4, vis a vis a more typical closed-back IEM. I answered (screenshot below):
Like
@bmichels, my top IEM has been the full-range electrostatic Shure KSE1500, since its release. (
We shot a whole Head-Fi TV episode about the KSE1500.) It's the most resolving IEM I've heard; and, given the excellent isolation it provides, it's rather like listening to a fantastic full-range electrostatic headphone while sitting in an isolation chamber. However, when I heard the Audeze LCD-i4 I knew straight away we might have a low-level resolution challenger for the KSE1500. Direct comparisons between the two are challenging, though, with the KSE1500 being so closed, and the LCD-i4 being so open.
I wasn't kidding in that Facebook chat--we did end up visiting the
Roush Industries NVH Lab the next day to use one of their anechoic chambers to essentially eliminate the the
closed-versus-open / isolating-versus-non-isolating difference between the two. Here's a quick video we shot while there:
As you can see, we ended up going with the Chord DAVE instead of the Chord Hugo 2 once we saw that we had ready access to a power outlet, and to afford as much detail retrieval performance as possible. While the Hugo 2 is as close to a portable DAVE as I've yet heard, I'd still rather listen to the DAVE when it's readily available. Day to day, though, because I'm not often in the same place for very long, the Chord Hugo 2 has been my primary source since its arrival.
Here are some photos:
So what were the key takeaways from this visit?
- When you essentially completely do away with external noise (HVAC, traffic, people moving around, fan noise, etc.) you realize even more how open-sounding the Audeze LCD-i4 is. Even outside the anechoic room, the open-back Audeze has an obvious (and not surprising) advantage over the Shure KSE1500, in terms of openness, width, and depth of soundstage. With the isolation--with little to no external auditory distraction--it's like my brain allows the soundstage of the LCD-i4 to fully realize itself. I wish I could shut the world out like this on-demand (without having to visit the lab).
- In terms of low-level detail retrieval, my impressions when listening inside the anechoic room to both the LCD-i4 and KSE1500 does suggest that the LCD-i4 does indeed resolve (to my ears) micro details every bit as well as the KSE1500. Again, its ability to resolve low-level detail is obvious even in a typical room setting, but listening to it in this silent lab environment is a very impressive display of the LCD-i4's full resolution.
- The detail retrieval of the Chord DAVE --> KSE1500 and Chord DAVE --> LCD-i4 combos is mind-boggling.
In case you're still wondering, then, why on earth anyone would want an open-back in-ear of this caliber (and price), I'll repeat what I said in the Facebook chat: It's like having a flagship-class open-back headphone that fits easily into my backpack. It's so small that I carry it in addition to my closed-back in-ears, so that I have the choice between closed and open depending on my setting (and mood).
As I said in that short video above, we'll be putting together a
Head-Fi TV episode about the Audeze LCD-i4 relatively soon, so I'll have more to say then.
NOTES: The Audeze LCD-i4 we used for this is a pre-production unit. A production-version LCD-i4 will be arriving soon.
