Headphoneus Supremus
Philips Fidelio X1 or X2 added. Still don't know which to pick lol.. Leaning towards the Philips Fidelio X2 or AKG K712 Pro.
The 712 reportedly was released to "correct" the perceived shortcomings of the K and Q 7xx headphones.
More specifically, a tendency towards edginess in the upper midrange and treble, and a thin-ness
to the bass. While retaining the great sense of openness, broad soundstage, and ...precision,
of those other models, particularly the early "K" models.
It did correct those issues, in the opinion of many...(me included )
But hey, they shrunk the soundstage! Pro's and con's about that
since many thought it was too large.
A little less treble, a bit more roundness to the bottom end,
a smoother upper midrange...and there's the K712, more or less.
But,
OP> Based on what you've mentioned here, that "added" bass
is not going to be sufficient for your wishes.
The X1 is an excellent headphone with some comfort issues,
unfortunately. (Check the review in Inner Fidelity, among
others.) The bass is terrific for an open headphone.
I've not heard the X2, but that's where I'd be leaning if I
were in your shoes.
Hope this helps
