just to get an idea on the KEF sound signature, i audited the iQ10 for quite a while at a dealer place paired to a marantz cd player and marantz integrated amp (pm6003 i think). it still sounded a bit on the bright side.
might be because the unit have too little playing time on them, but the monitor audio bx2 sounded awesome out of the box.

was considering the kef new q series or the monitor audio bx series because of the good review, but in the end upgraded to the monitor audio as i preferred their sound more.

the dealer didn't have the new q series to audit but i heard the iq60 (IINM) before and it still strike me as a bit bright to my ears.

preference i guess.

again, purely preference but i (we) did tried putting a bookshelf of similar series as a center channel flanked with floorstanders of the same series vs the dedicated center speaker and the dedicated center speaker sounded better.

and turning on and off the center speaker (while sitting dead center), i still think a dedicated center speaker sounded better.

the last few days i spent a few hours auditing the q300, q500 and q700 with a q600c center speaker plugged to a marantz sr7005 for movies and then run the setup through a marantz cd6004 + pm6004 integrated amp for stereo.

played the same transformers dark of the moon scene which i am familiar with, then run tracks from norah jones, michael buble and best audiophile voices 2. and just for fun after spending the few hours listening to the 5 star whathifi awarded setup we run a pair of b&w 705 through the same cd6004 and pm6004.

i'm a freak for midrange. so i'm biased towards the sweet midrange of the b&w. the kef q series have better sense of space and more emphasis on treble. which is a good thing for movies. but not so for music. playing music they still sounded a bit thin and dry sounding to me.

the 705 is a used set, selling cheaper then the q700, at the same range as the q500. not in the same class i'm sure, but since it's cheaper than the q700 might as well try it out.
too bad already booked by someone and awaiting pickup.

if i were you i'd bring the 609 to a place that have the speakers to test it out.
polite speakers (laid back) which sounds really good for music don't have that extra zing that a brighter/more aggressive speakers have especially for movies. tho that extra zing could probably sound harsh and fatiguing when playing music.

so there's a compromise that you have to make. as to how much compromise you could live with is a question that only you can answer.

wires made from silver and/or have some sort of silver coating in them generally carries the usual silver sound signature, which is bright. not a bad trait if properly matched as they're also transparent, highly detailed, lots of sparkle, open, wide and the usual characters associated to high frequency emphasis.

having heard the kef q, xq, iq series i associate them as being bright. a silver cable to a bright speaker might not fit some people. though some could tolerate such piercing sound, i definitely could not.

i've seen hifi choice midlands park (seeing that you're in penang) have a few models of the q series. and some chord silver cables the last time i was there. they also have pioneer and marantz avrs on display. try and visit them for an audition to gauge your level of tolerance.
