I've had a few days to listen to the Evo, so I thought I'd drop in and share some thoughts on what is now one of my favorite IEMs. I owned the LX (several times), LX SE and still own the Odin, so EE sound is not new to me. I should also mention I never even used the stock cable
I was most excited about the bass and it has exceeded my expectations. I loved the LX bass as well, but always found it to dominate the signature (not in a bad way) and the Evo deviates here with similarly deep and punchy bass, but a more balanced tuning overall to my ears. The bass, to me, is sort of in between LX and Odin where Odin has that amazingly tight and deep sub-bass focus, but Evo brings in more quantity and a larger amount of mid-bass which I welcome. The low end in general is super punchy, controlled, textured and moves serious air when the music calls for it.
Into the mids, I hear a lot more energy and crispness where the original had a thick, natural mid-range. Into the upper mids, vocals can have a ton of energy and sound forward depending on the track, which I enjoy a great deal. Electric guitar solos resonate in an engaging and textured way - I find that the Evo works incredibly well for band-based rock music and things of that nature.
For treble, I always wanted more from the OG and I am happy to have received it here. Treble sounds sparkly without being unnatural, though it's smoothed a bit compared to something like Odin. Traillii set the treble benchmark for me, but Evo is tuned for more of an all-day listen in this department and I have no complaints. The whole package is, without a doubt, a keeper for my tastes. I've tried a bunch of genres as well and I haven't heard it sound bad on anything yet.
On the topic of the BCD, well, I also own the Mason FS and my take is that the BCD adds texture/air throughout the frequency range. It's really hard to say, though, because I cannot hear the same IEM without it to validate. But, notes are so well-defined and have an almost physical weight to them, so my simple brain tells me that's the BCD
As always,
@MusicTeck is great and got this thing to me quickly and also a huge shout out to
@doctorjuggles for this gorgeous cable that I'm loving on Evo. It's an 8-wire gold-plated silver and it provides a very resolute, detailed sound with great clarity. In comparison to Centurion, this is a touch more natural and smooth where Centurion gave some serious energy to the upper frequencies. Anyway, pretty generic thoughts I suppose, but I'm extremely happy with this IEM and it was worth the wait.
