Just bought an used Rogue Metis (with GE 6SN7) from a nice gentleman in Canada; unit was relatively quiet IMO with my listening volume control up to approx. 12 O'clock. My other components as follow: power amp: McIntosh MC275, DAC/transport: EAD 7000 MkIII/1000T, speakers: Clements Little "d". The Rogue is my most recent addition, and definitely an improvement, replacing a rather nice N.E.W. (this USA manufacturer was purchased by Cary in the late 90's) model P-3 triode preamp.
