Avantgarde Horns and tube amps. I have AG Duos driven by my tube amps (Verdier Control B preamp and valve psu and Quad IIs) and a vinyl front end (Platine Verdier, Schroeder model 2, Allaerts MC1B). Vocalists really ARE in the room with you. Listen to a well set up pair of AG horns and you'll be stunned by the vocals.
