You are asking for the holy grail. I believe that the only preamp that sort of match your needs is an older BAT-3P? All BAT preamps are balanced and this one has remote and even an optional phono card. Tube changes should not worry you much....but then, there are preamps that use 6 tubes, the First Sound used just 4,2 0A2 tubes (around $10 a pair?) and 2 6922 or 88cc tubes, these are a little more. But, you do not need to get carried away with people telling you that New Old Stock tubes are better, modern preamps are fine with new, well tested tubes that do not have to cost you a liver or a kidney.

PS: The BAT I am telling you about runs easily into around $1500, used.
