No contest, buy the ls50 wireless, it is active = better bass, uses DSP (maximized use of the drivers, room / Speaker placement correction, wireless streaming. It is the best kitchen system and will have a better resale value.
i would not invest in $$$ high End electronics for the passive ls50. After all it is not that good. It is a low efficiency speaker with little bass and poor dynamics.
if looks are not that important I would buy a pair of JBL LSR305 or lsr 308, 1.5m Audioquest 3,5mm to cinch cable, chord mojo + poly. This is the best bang for buck system of this decade. Lacking ultimate resolution and neutrality of higher end systems but with dynamics many higher End speakers only can dream of.
