a good amp then good speakers with good cable in between. what are the tannoys that you aquired racehorse are they the reds. in aus m^a(t)h try vaf, krix, tannoys, kefs, go to all the places that sell good quality gear with a cd you know really well and listen to them, do not let the sales guy try and play some eagles or similar stuff that they like through them because they do that to sell speakers to idiots it must be something you listen to regularly and know really well (a cd with your voice recorded well for example also helps). the domestic tannoy boxes are great and krix and vaf are both beautifully made australian boxes. tannoy being the oldest loud speaker maker in the world holds great reliability but can be very pricey. most cinemas in australia run krix speakers
