Hi @mitchco
I saw your measurements of LCD-4 vs LCD-5 here
And your comment:
But this seems completely opposite to @oratory1990 's plots against Harman Curve cc @Sean Olive
The general trends of your plots are similar too, especially the main 'problem area'.
I know you know all the Harman research for speakers but for headphones, Harman research would suggest LCD-5 is more neutral and LCD-4 would be dull (exactly my subjective response too).
I saw in your review that your EQ improved your subjective experiences but that would have made LCD-5 deviate even further from Harman curve.

The LCD-5 starts to roll off around 70 Hz and similarly to the LCD-4, about -4 dB at 20 Hz. The LCD-5 stays flatter than the LCD-4 until about 500 Hz where the response starts to rise with a broader peak from about 800 Hz to 1.5 kHz. But as one can see a sharp rise with +6 dB upper midrange energy from 3 to 6 kHz. Not only quite the departure from the LCD-4, but also brighter even than the Raal Requiste SR1a. I must admit the LCD-5 are the brightest headphones I have listened to and measured. Seems a bit unusual for a flagship headphone, especially given how relatively neutral the LCD-4’s sound and measure. Fortunately, headphone equalization is a thing. Let’s see what can be accomplished.
