I got my Bryston 4B Cubed in October and have been enjoying it very much.
When I first got it I noticed a little transformer buzz but was not too worried about it since I used to own a 4B ST that also had noisy transformers.
I emailed Bryston support to ask if it is normal to hear the buzz when my ears are 2 feet away from the amp. They told me it is considered acceptable if the buzz cannot be heard more than 3 feet from the amps, therefore mine would be considered acceptable.
But lately with the colder weather, I do more late night listening when my room is really quiet and the buzzing is starting to bother me even from my listening seat. Especially between tracks, I hear it as if it is room ambiance in the recording.
Anyone else here notice the same issue with their 4B Cubed?
James, do I just have to learn to live with it? I don't want to go thru the trouble of sending it back if nothing can be done.
