Just received today my new 15.4mm 150 ohm variant drivers!
I stay you guys tuned for the first try with them tonight
And as promised, here are my quick impressions of these drivers.
There is for sure much enjoyment in the mids and highs, but bass feels lacking punch and dynamic, does not rumble at all (almost no subbass). Slightly sounding "congested", not very natural and transparent.
Soundstage is average but coherent and intimate.
I tried some MX500 shell modding to see but unfortunately drivers does not respond well and remains the same sounding. I tried also to remove the white coton tuning (that we can easily find on ali), and put another more common but same sound. I tried without anything and same sound too.
I recommend them for musics that don't requires much bass, better for vocals or instrumental I would say.
I decided to remove them to solder again my previous 150 ohm reference drivers (that I shared recently).
From my DIY experience I remarked that the sound is altered by drivers which makes 80% of the overall sound (approx), other 20% are : 10% on tuning shells tune, and 10% in the quality wires used (copper/silver).
When a driver sound bad from the beginning, no need to let it burn for so many hours to expect any changement, as it will already sound at least 90% of their best. That is why I dont spend much time keeping the driver units I don't like (don't worry so much, as I don't throw them after that
)
I'm currently experimenting some various "coton" tuning (or other materials), into yuin shells, we can do incredible changements which affects the sound to perfectly match our tastes.
Next step: can't wait to receive my 130 ohm beryllium drivers, and the 32 ohm PET recommended by
@HungryPanda !
I expect a lot from these and competition between my reference 150 ohm will be hard I guess.
