How much to spend to beat $1200 10yr old speakers?

i've had my KEF reference 102/2 stand-mount's(paid $1200 new) for about 10 years now and still enjoy them-but how much would i have to spend on new speakers to beat the ones i have in all or most respects- for example, i've heard alot of good things about the Quad 11L's for $600- is it possible to get more bang for half the price these days? or maybe 3/4 the price with say the Meadowlark swift? any other brand suggestions welcome, thanks
