I own a tempest 2, have owned the sphinx 2 and the RP1. I can attest to how incredibly noisy all of this gear was. The sphinx 2 was less so and was actually manageable as my speakers weren't very sensitive at the time. The RP1 created a ridiculous amount of noise unlike any other preamp I've ever owned. It was sold. The tempest likewise has a crazy unlistenable amount of noise compared to any other amp I've ever owned, even when just using the onboard passive preamp, a hum X, conditioned power, it generates massive noise that is clearly audible at 15'. I've decided to take a break from Rogue Audio products because of it.
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.
