No i wouldn't swap, not even for £500 more!
Its the simplicity with which it fits into my system. I am sure that there are better separate systems for the money but my system wasn't. It looks great in the lounge, i have the sub on the bottom shelf of a heavy wooden TV stand with sound projector on top. No rattle.
I see it like this:
?300 - amp, ?300 speakers, stands ?80, cabling ?50 = ?730
I only paid ?720 for the YSP- 2200! No mess, no clutter, brilliant sound.
After hearing the Yamaha i would consider that brand as an amp route, but i can't think of any speakers i would like up to £500.
Of course if i had a seperate cinema room for my projector i may consider a full speaker package but would definetly try the YSP first.
