I'm after some advice on speakers, I've not got 1k too spend though

I bought this yesterday
Onkyo CR505 DAB
for my bedroom music (barry white, Lionel richie etc )



Play varying music ranging from damien rice, audio slave, kasabian etc

The units awesome for £220 very impressed at the clarity and volume and I've only got it hooked up to some el pantos panasonic Stand mounts.

I'm not sure on whether go for two floor standing speakers or stand mount size, I presume the floor standers would provide a punchier sound and have a wider range.

my budgets up to £150 ish if you could reccomend anything.

The unit above is only 25 watts per channel and it also has a sub output.
Would it be able to drive say 100 w floor standing speakers well? Its slowly destroying my panasonic efforts at the moment

Cheers,
steven
