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.

You indicate that you purchased this new. You should take it back to the dealer (if you bought it locally), and if the problem exists when the dealer hooks it up they need to address the issue. If it can't be duplicated, the dealer should be able to advise you so you can determine what system interaction is causing this.

Also, if you are comfortable doing this, power down the unit and remove the power cord, then remove and reseat all of the tubes. It may resolve or alleviate your problem.

As Bill_k suggested Rogue has great customer service, and you can call them too.
