Not sure how this would translate to you RAAL headphones, but I’ve warmed up my sound by wiring a low value cap across the amp terminals. You can get a couple of inexpensive orange drop caps to see if it works and determine which value hits the spot. When you find a value that does what you want you can get a quality film cap.
I used mainly 100nF and 47nF, but you can drop the value much lower if you feel it attenuated the tops too much.
Top shelf 100nF film caps can be had for around $30 a pop.
