So my L12P came in and i have to say, i think we found a real winner here after one slight mod.
First thing that hit me was the soundstage. This IEM has the widest soundstage I've ever heard in any IEM currently or previously owned, almost HD800S type stage. Due to the wide stage, Mids. are a bit recessed but I fixed this by using Filter 2 on my DX240+AMP8 MK2 pairing.
Bass is just the right amount. L12P is very resolving. treble is just about perfect but yet smooth, almost EST like smoothness yet still clear.
Initially it also had too much mid-bass and treble wasn't as extended as I'd like.
What I did was remove the grill to reveal the 4 sound bores. The little wax grill has no filter of any kind behind it and so has nothing to do with the tuning of this IEM. grills actually mess with mid and high frequencies the most. also has an effect of increasing bass bloat a little.
With the Grill gone, this thing is now perfected. This IEM presents the song the way it was recorded. I was very impressed when I played some tracks with lots of instruments. L12P didn't even blink. it lets you hear everything in it's position from left to right and distance/ positioning of instruments.
L12P has more mid-bass than OG monarch which makes bass guitars and deep low piano keys sound more realistic. Monarch has slightly sharper (not in a bad way) treble vs LP12P which still very resolving never the less. This is with zero burn in.
Burn in continues today.
Fit is amazing (Will fit even a baby lol). Reminds me of my QDC Anole VX. You put it in your ears and forget about it. All your brain focuses on is the music unlike my OG Monarch where you feel the size the longer you listen.
Stock tips sound the best (Wide bore with a very short stem, shorter than anything else I have). Don't know what kind they're are but I put the extra set on my TheiAudio OG Monarch which helped widen it's stage a little more. (I experimented with AZLA Short and exslastic, spinfit 100 Plus, JVC spiral dots)
I also tried different cables from 100% copper, to $350 Gold, silver, Palladium plated ones but copper + silver plating sounds best to my ears.
At $569 this is a real steal guys. Get one asap and remember to remove the grill.
