Does the Emo/450w have RCAs for the L/R fronts?
- If so you might try running those into the integrated…
- It may be the preamp section of the Emo more than the amplifier section.
- So a way to figure that out could be worthwhile.
- Confirming that those two channels of speakers sound OK on the Marantz would also be worthwhile. (It could be that the speakers need to move around a bit.)
