Looking for some sound advice, if you’ll excuse the pun. I have a Nord Purifi power amp with a Rogue Audio RP1, mostly I play CD’s through a Roksan Caspian CD player, as well as LP’s on a Michell Focus One turntable, I know the Nord is dead quiet, because I previously used an Arcam Amp as a preamp, wasn’t too pleased with the sound though. The rogue gives a much better all round sound stage , and with remastered CD’s it can sound stunning, but there is a hiss, not noticeable when playing but to my ears very noticeable in the absence of any music. Also the volume control clicks when turned quite loudly, and sorry to list a multitude of ‘problems’ but if you have the phono stage on and leave the turntable playing, switch the selector to Line you can still hear the turntable through the speakers almost as if it is bleeding through. Is it a case of finding someone to service the Rogue ?
