Hey ohhourami, I read about these mods on your HE-6. Just want to have feedback from what you've done since I just completed the full Fuzzor mod with similar initial impressions of loss upper treble with Vegan pad. Interesetingly, the bass has gone down slightly too which is quite opposite of what most of H-6's modders achieved. I have also used the tape ring and mounting the pads directly without the original plastic ring.
With the 1/4 disc felt and foam piece removed, I applied the full Fuzzor felt mod and after attaching the Vegan pad back, my immediate impression was a hugh loss of upper treble to the point of sound worst than my LCD 2.2! And this is with a fully open grill mod too! I decided to try the leather version of the LCD pad and a good part of the treble came back. This pretty much confirms that the Fuzzor as we all already know that it dampens and control the high freqs. However, it seems as if the Vegan is an additional dampening material to reduce the highs further.
At the moment I prefer the leather LCD pad since it brought back the missing highs but still like the softness of the Vegan. I am thinking of removing some of the Fuzzor felt as some of you have already done and determine what is a good compromise for my ears. I am still trying to understand why Hifiman placed that 1/4 disc felt where it was - does it also affect bass response or strictly controlling the mid to upper range behavior??
Also looking at your freq response, you've gained 2-3 dB on the low end after the mod or was it due to some other mods?
Anyway, this hobby is great and keeps getting more interesting now with the HEK on the horizon!!
