Having never heard it, I cant speak to the Perfectwave, but you are doing your EMM DCC2 SE no favors by hooking it to a Levinson 37 transport. Nothing wrong with the Levinson per se (I used to own one) but having heard the EMM with the CDSD transport... which unlike a regular transport enables the DCC2 to act as the digital systems master clock... I can assure you that youve heard only the "tip of the iceberg" as far as the DCC2s performance is concerned.
