The transformer hum and slight amount of noise is normal. Hey, what do you expect for a 100wpc tube integrated amp that only costs 2,200.00? I never tried the phono stage, so I can't comment on it. If you want less noise and more refined sound, go with the Prima Luna HP integrated that will cost you 4,300 with the EL34 tubes and only put out 70wpc.
Rogue Cronus Magnum (hum/noise)
Any other Cronus Magnum users care to share how noisy your amp is? I can definitely hear a bit of transformer hum/noise when close to the amp itself, and within about a foot or so I can hear hum/buzz through my speakers. I've lived with it as it's not really noticeable when music is playing, I'm just not sure if that's normal or not for this amp? I think I can say with certainty it's not a ground loop issue, and different tubes don't seem to effect it at all. The noise through the speakers stays constant and does not change with volume.
I've asked Rogue and they said it's normal for little noise, but I don't know how much is normal??
The phono section also hums (a lot more, amplifying with volume), especially when the volume hits about 12o'clock, but this isn't too big of a deal for me as I use a separate phono pre.
