Given the fact that both Golden Atlantic and Big 7 are the same price, do they sound equally well? I am referring to the SE version with tube rectifier and volume control. My guess is that with Big 7, you can tube roll and if you put on some very high-end 300B's like the Takatsuki, then the Big 7 could potentially sound better than Golden Atlantic. Is this correct? Does anyone have experience comparing the two? Thanks.
