'Talking' ain't necessarily 'Walking'
It's the easiest thing in the world to 'talk' a good product, and 'talk' improvements to this, that, and the other.
I'll believe it when I see it.
You've 'talked' your product Up a heck of a lot, Fang, and along the way, implied that competing products use inferior approaches.
In short, you have a lot of your own talk to live up to.
I, and others, will be watching with interest to see what (eventually) turns out to be real and what turns out to be hyperbolic vapour.
As I've said a number of times, if the 901 turns out to be as good as you claim it to be, I'll seriously consider opening my wallet; it's just that until this thing really enters the marketplace, it's just a fantasy paperweight.
For all it's faults, the DX100 remains a fabulous-sounding single-box portable player. I respect it for that. It's real and it sounds great. When I have the cash to spare, I'll almost definitely be buying another one. A real fabulous-sounding player (even one with bugs & quirks) trumps a fantasy-perfect player every time, no contest.
People say the same thing about the Tera Player, that has an amazing SQ. Mind you i had DX100 for a whole month before i sold it, the SQ was beautiful but the player wasn't perfect.But if Hm-901 turn to be even better without the pop up sound i will buy one.Also iRiver AK100 might be good enough for the money, time will tell..
