soundstage any good?

Yes. It's averagely wide but more importantly it has good depth. To me a lot of universals don't do depth very well but this one does.
Impedance is 12ohms. This is very low and this causes changes in the frequency response when the source being used distributes a significant amount of impedance. Thus these will respond at their best to players with low-output impedance. The general rule is to divide the impedance of the headphone/IEM by 8 to know the maximum desired output impedance, 1.4 is the maximum desired output impedance of the FXT90 (12/8=1.4). This breaks it down to the following players via headphone out
Clip+/Fuze/Clip Zip?/S:Flo2=0.5 output impedance
Iphone 4/Iphone 4GS?=0.9 output impedance
Iphone 3GS/Cowon J3/Nano 6g(7g?)/Fuze+/GoGear Vibe=2 output impedance (these are unfortunately a bit higher than desired but are next best thing).
Whether this is a flaw or strength is up to the user to decide. I personally think it's forward thinking as the output impedance of players should be decreasing in the future. Besides, one should lean towards low output-impedance players anyway due to the performance benefits IMO. The FXT90 isn't alone in this, there are many other IEMs with very low output impedance. The upcoming Sony XBA-4 has a 8ohms and even the good old Triple10 has a very low impedance,for example. Fortunately many amps have an output impedance that's lower than 1, the Fiio models being a good budget option.
