pmb, the 270 is an otl and the fila is a class a transformer coupled amp. the otl will sound very open and natural and the fila offer wider bandwidth in the bass and expanse. both great but different. either of them will not be everything to everyone. i know of many that cannot live without the otl's uncomplicated character and know of as many again that cannot live without the superior tonal balance and depth of the class a transformer coupled amp.
