Mark.......I also owned a pair of Altec Valencia speakers for years. I drove them with a McIntosh MA230 integrated amplifier, solid state preamp and 30 watts per channel tube power amp and a single chassis. The Valencia's had the same 15' woofers, plus the same horn and compression drivers as the Voice of the Theater but were easier to blend into home decor.
