best speakers for marantz 8b amp


looking for speakers to pair with my 7 & 8b system. i can spend up to $4000 but my apartment isn't all that big so i need something smaller in size. recommendations for highly efficient speakers?

congrats....they are spectacular....speaker recommendations....castle harlech or howard. musical, tonally accurate, nor placement fussy, small footprint and a $ bargin......play well with moderately powered push/pull amps, and have furniture quality as good as speakers in the 10k up range.
