I have personally heard mags with an underpowered good sounding tube amp and it was bad. Sound was plain with no detail. Everything was foggy and would not play loud by any means. I would suggest after what I heard is to have at least a 50 watt tube amp. If you were to go solid state I would suggest something of at least 100 watt.
Good Luck and keep us posted of what you buy...
