Snell Type A's. Tweak your system upstream all you want & they just sound better & better(& better). A pair, depending on model AI-AIIIi, in good condition will run you 500-1500 bucks(make sure the woofer foams have been replaced). I've heard speakers for 10X the money(either end) & I'll still take my pair of A's.
Snell CV's for $900 are also quite a bargain.
