@babadono I do a lot of mastering for electronic music and sometimes I use the 4BX for playback just to check how good they are, but yes you are right the master will be only as good as the original pre-master mix down track/s. Anyways I was wondering if you could mod mine similar to yours but with no external PS and no balanced xlr I just want it to sound better with those THAT components and the LME49720 op amp upgrade. My PS transformer is just 100 volts there is no provision for multi voltage taps on the PS.
