@karl_desch I suppose it's horses for courses, I tried this with my friend also listening we both felt that putting it through the SUT gave it more tonal colour, body and musical engagement. Of course there are 3 variables in that yours is an XP-27, with a different SUT and cartridge. I would be interested to know you phono stage history as to how you arrived with the XP-27.
@benjie as stated before I don't have a gain/volume.
