I personally feel the X5 is a bit too big, as well, even though I don't dispute your above logic.
When I look at the DX90, I think they have done really well to keep it down to only 140g and 64 x 100 x 17 mm. They have shown that a compact DAP can be made, at a reasonable price, without compromising audiophile performance.
I am a fan of both iBasso and Fiio, so please don't anyone think I am trying to 'name-drop' iBasso in a Fiio thread - I'm only mentioning them because the DX90 and DX100 are relevant to discuss in the context of choosing features for a new flagship Fiio DAP.
It's relatively easy to make a DAP that has audiophile performance - but what is the point if it's still too big to carry in a trouser pocket? You might just as well use a stack, and there's already a very wide range of products, from numerous vendors, to stack together...
It just annoys me when people who are mostly desktop-gear users push for desktop features in a new DAP as a higher priority than size/weight. This is the mentality that they will use the DAP in their car or in their rucksack, on the way to work, and then use it on their work desk during the day. This is utterly pointless when they could easily use a transportable stack to serve the same purpose. There are those of us who desire as many audiophile features as is reasonably possible but still being able to use the DAP whilst walking with it in a trouser pocket and not wobbling around all over the place, looking obscene to passers-by and damaging the pocket / pulling the trousers down.
This is why I previously stressed that it will be extremely important for Fiio to figure out which is their target market for the X7 (http://www.head-fi.org/t/713734/how-heavy-can-you-accept-in-order-to-achieve-better-sound-and-appearance#post_10444918)
Do Fiio wish to build another DX100/HM-901 brick or do they want to try to offer something more compact that will be usable by people who actually wish to use a DAP in their trouser/pants/jeans pocket all seasons of the year?
Until that has first been decided, all other discussion about the X7 is, effectively, redundant.
