I've emailed Rogue again and as both units demonstrated the various noise I have asked if they think this warrants a return, I guess the ball is in their court so to speak, there is plainly an audible hum and the odd unequal hum from the speakers, if that is enough to convince Rogue their is an issue then so be it and I could send the unit to be checked/repaired, part of me does think that maybe that is just the design of the unit, admittedly that's not optimal but I'm currently not willing to start playing around with retail returns over something that doesn't actually affect my listening, I do however understand how some would not find it acceptable, $1500 is not crazy money but you still expect a quiet unit, there are plenty of cheap amps that are silent.
How quiet is your Rogue Sphinx?
I have a new Rogue sphinx, I don't recall the unit I demoed to be especially noisy but I do find my unit to have some noise despite other owners describing the model as 'dead quiet'.
In both 'standby' and 'on' there is a quiet though audible hum coming from the right hand half of the unit (maybe I can hear it through the vent on the top). You need to put your ears pretty close to the unit though.
There is also a similar hum to be heard through the mid/bass unit, audible about 2 feet away. This is aside from the more common 'hiss' that is also present. Oddly if I turn my balance control left all the way, the hum becomes much louder through the right speaker only and can be heard about 10 feet away. If I turn the balance to the right the original hum in the left speaker actually decreases in volume!
I am used to speakers having a hiss but the question I ask is do any other sphinx owners notice this extra layer of hum/buzz that varies with the balance control in this way? Is your actual amplifier unit dead quiet or does it have a faint hum also?
Just trying to figure out if my unit operates typically or otherwise.
Thanks in advance.
