I think the comfort of the HE-6 is decent - for me anyway. However, a member named Lohb makes a great suspension system that is usable for pretty much any of the early HiFiMan phones. Really nice workmanship.
Here's the setup - I've had it for two weeks now and coupled with the leather Audeze pads, makes the comfort incredible.
I like the look of that - especially how it fits bald heads like mine
I have been using a seat belt protector over the headband and that provides excellent comfort also, but can get a little warm in summer (which is about to start in my part of the world). I'm thinking the suspension system might provide the comfort AND not bake my brain in summer.
On a HE6 related topic, I was doing some A/B testing over the weekend with my modded HE6 driven from my WA5 vs my LCD-X driven from my Taurus Mk2 - and the HE6 won everytime.
The Taurus Mk2 + LCD-X combination is very, very good - reference quality, I think, but the WA5 + modded HE6 has it beat in everything. The imaging and soundstaging of the HE6 were a clear notch above the LCD-X to my ears. Going back to the LCD-X almost felt like a 'veiled' version of the HE6 - a little less detail, a little less soundstage and imaging, not quite the same inky black background. The only time the HE6 didn't outperform was a few moment where the treble seemed to get away slightly - I'm wondering if this was because I did a lazy 'partial fuzzor' rather than a 'full fuzzor' mod - as shown below.
Next I will mod my HD800 and see how that compares. The LCD-X, despite being an excellent headphone, is clearly outclassed by a well-driven and modded HE6 IMHO.
Are other HE6 + LCD-(whatever) users out there finding the same thing? Or am I on my crazy lonesome in this view?
