I'm not sure what's wrong with some people's hearing on the discussion pages but the SR 9 is by no means 'bright', nor does the FR graph make a lot of sense either but that's a whole other story...
I am just curious if said people who mentioned this headphone as being bright have actually heard this & what are they using as source ?
I made a comment several months ago regarding SR 9 sound sig which I will repost :
'Subjectively & personally, SR 9 is better than the MSR 7 sonically & technically.
Though 'better' is relative & I suggest you demo if possible as only you know what you like nor does anyone else have your hearing, head & ear shape, etc nor should you judge by a sole review...just my humble two cents...
There are other head gear certainly which potentially outclass this both technically & sonically but for the deal here, it is hard to be not tempted, even with standard drop waitng time.
This headphone requires good, well recorded quality sources to really shine & does matter, regardless the format.
A decent to good DAP or desk setup will make these work well too, provided said good, well recorded quality sources definitely apply.
SR 9 sound in subjective terms, is more refined with a lean towards more pro tuning where highs & bass response is concerned though by no means is this classed as pro audio headphones but sits somewhere between pro & consumer.
A good amp, tube or solid, not necessarily with DAC, will also make the SR 9 sound really good.
As per the sound signature, these are definitely not for bass heads but can handle good bass as stated.'
As a final point, considering how much this headphone goes for retail in most parts of the world, this is really good value.
Trust your own ears & your own opinions, also listen to as much good quality sources as you can, format is also largely irrelavant.
Hope everyone has a great day !
