Lamm and some Rowland preamps are multi voltage, so you may want to check out their amps, assuming they are in your price range.
120/240 V amp question
I am going to be moving soon and I was wondering what brands of amps can work well in either voltage scenario. Looking for an amp that can put out at least 150W per channel. I am thinking that most solid state amps can do this but not entirely sure. Bel cantos - i think?? Any other brands?
