Good point by Brf. If you don't want to purchase a separate phono stage at this point, though, keep in mind that you can use the built-in phono stage of the M6Pre in conjunction with the SLP-05. You would do that by connecting the tape output of the M6Pre to an input of the SLP-05, and setting the input selection on the M6Pre to phono. The line stage of the M6Pre, including its volume control, would not be in the signal path in that configuration.
