On units after serial number MZ0293xx27xxxx the improvement may be around 5.3dB, due to Marantz's upgrade of the original opamp. Some improvement can be made by simply changing the op-amp to the AD OP275, but for the full improvement the entire modification below should be performed. Note that the XLR-ECM switch now becomes XLR-Input Select.

Any alteration of a unit still under warrantee may void the warrantee. Performing this modification is at your own risk, and we can not offer any technical support with this modification. Insert SE01 here AD OP275 from WE02 pin 2 to RE18 Rec Level 100 22/50v BP 1
