there is still one more option to go.... two amps of different power rating but under the same family. Of course the ultimate option is to use two amps of different technology say vaccum tube for high and mid range plus a solid state for bass. This is not for amateurs because there are lots of tricky things must be used to make the sounds musical. 還有一個選擇......兩個具有不同額定功率但屬於同一系列的放大器。 當然,最終的選擇是使用兩個不同技術的放大器,例如用於高頻和中頻的真空管以及用於低音的原子粒。 這不適合業餘愛好者,因為必須使用很多棘手的東西才能使聲音變得音樂。
