Here is my breakdown of this song using almost all of my IEM's on hand.
You should really try the Auvio tips from Radio Shack on the FXD80, you owe it to yourself......those and burn in could really change your mind.....better details all around, even with the bass. Are you recommending the FXD80 as bass heavy, or are you hearing the wonderful detail in the bass?
Been using my fxd80 on the tube recently. Isolation is pretty decent for an open phone due to the deepish insertion, much better than FX40. Few things bug me about the cable though: I think the rubber things on the earpieces are annoying and seem to serve no purpose other than limiting insertion depth as the microphonics are still pretty bad with them; Why is the y split so long? Looks silly and forces me to use the slider, something I've never needed to use before.. ; Microphonic as mentioned before..
You try throwing those over your ears? IT eliminates all microphonics and is comfortable that way. They also stay put for me better too worn over the ears.
I usually wear all my phones over ear when possible (including FX40) but the rubber things that I mentioned I dislike also prevent a nice over-ear fit. It kinda works but it just doesn't feel right as the rubber things push the cable too far away from your ear. It is worth still wearing them over ear as you said, I just think it would feel more natural if they had a normal cable insertion.
(the sound quality makes up for it though.. I'm just nitpicking the things I would personally change)
+1 I thought those strain reliefs would be a pain, they're actually pretty good and aid with insertion.
And im in love with my FXD80's, they are such a great iem with my rocoo and some florence and the machine.
Bugger it, i'll throw them on now.
Goodbye driver flex!

Another Auvio vs. comply:
Comply tips usually muffle the sound. By using the reversed side, you get the benefits of the foam without the muffling effect.
I think FieldingMellish started it, but the brand is Auvio, and not Auveo. Just wanted to clarify that. 
I have asked this before but no one replied, how is the Timbre compared to the FXT90?

Very true. I echoed these sentiments in my reviews/impressions. OOTB, the midbass is relatively flat, midrange/upper midrange was slightly forward.. along with the treble/upper treble & sub bass being slightly accentuated. They certainly sounded bright.. OOTB.
I've got well over 100 hours on mine, now.. and they've noticeably changed. The midbass has filled in, adding warmth.. but not interfering with the timbre of the midrange (vocals sound fantastic on the 80.. very clear, dynamic, transparent, and detailed). Treble has certainly smoothed and become more articulate. As I said, the treble will knock your socks off, ootb with crispness & sparkle. In time, they really settle down, smooth out, and provide better balance with the rest of the spectrum. The treble remains fantastic with it's sparkle, air, and clarity.. but it sounds less colored and bright... and more articulate and better suited for longer term listening.
If anything, though.. these lean to the warmer side of things now (as the midbass lift is more apparent, but impressively tight).. the treble isn't rolled off or excessively smoothed over like you might expect from a stage monitor... I still marvel at their clarity, presence, and sparkle. This coming from a self-confessed RE272 fanboy.
That's what's very enticing about this sound.. the delicate walk between a colored & balanced sound. To hear it done this well.. let alone at this price point.. is truly astonishing.
I'll repeat what I've said before for those new to the 80 and evaluating it.. the 80's are sensitive to recording quality: it's not hard to hear poorly recorded stuff sound shrill or wonky. DO NOT mistake this as the character of the phones. GIGO.

Not sure if any of this answers your question, but here ya go..
FXD80's timbre is better.. which is some high praise cause the FXT90 has excellent timbre.
People need to go back and read my FXD80 vs. FXT90 review.. I think I summed up a lot there.
tl;dr? The FXD80 houses the FXT90 in every conceivable way.
I'm sorry if I didn't read your post, I will try to find it.
It's hard to imagine the FXD80 trumps the FXT90 though...
From the price point, the FXT90 is still more expensive right? Correct me if I'm wrong
