Hi John! Man in a Suitcase! I too have been traveling a lot lately...composing this msg on my phone in the Miami airport. Assuming you travel with laptop, I suggest a Squeezebox, ICE amp, and speakers of your choice, maybe some of your single driver specials. The newer ICE modules use SMPS, and my mono's weigh about 2 lbs each with 6x6x2 inch Al case. AC voltage adaptable.
