I have built a lampizator srpp to replace the op amps in my cd player......After various tweaks I listen in complete disbelief at the sound coming out of my speakers...its crazy ...jaw dropping.......BUT!!!!!!!! I read in Morgan Jones that srpp is the worst choice for an output stage due to its distortion.....Jones does not conclude what is the best output stage....and so I am very confused...My srpp recieves a signal from a voltage out dac....the dac also gives balanced outputs (I do not use them)...the srpp feeds two tripath 2050 amps....so what do I have to consider when I try another output stage? mu/beta/differential/cathode I am lost.....or is srpp the best for the job?
