So, I’m trying something a little different. Now that I have the HD58X, I actually have something that’s naturally pretty close to the Harman target (except with a bit less bass and a bit more treble, both of which suit my tastes well). Going back to the LCD2C, I’ve become interested in what makes the LCD series special and just enhancing that a bit. In that series, the most special is the LCD4. Now, I’m sure the LCD2C can’t replicate all the technicalities (in particular the speed of decay), but its distortion is actually competitive and I wondered if bringing the frequency response closer to the LCD4 would yield any dividends. As usual, diyaudioheaven is a valuable resource. Solderdude compares the frequency response of the LCD2C to the various other LCD series headphones. What seems to make the LCD4 different from the LCD2C are two broad differences:
- No peak at around 800 Hz
- Slightly higher level of treble starting at 2 kHz and up
So, I made an EQ profile to roughly mimic the LCD4:
- Peak/Dip -1.5 dB at 825 Hz Q 2.00
- High Shelf +6.0 dB at 4 kHz Q 0.47
I have to say, so far I like it. As noted before, the dip at 825 Hz makes vocals sound just a tad more natural. The slight treble boost across a broad range opens up the sound somewhat, seems to improve imaging a bit and helps percussion in particular sound a little more punchy and sparkly. It still preserves the general character of the LCD2C but gives it a little shot of adrenaline. So far I like it.
