On my replacement amp you have to put your ear less than 6" from the speaker to hear the faintest buzz which is absolutely no problem whatsoever. If you weren't listening for it you really wouldn't know its even there.
Has mentioned my first amp you could hear audible humming at 12 feet, which at best meant you had to turn the amp off if you wern't playing a CD as it was so annoyingly intrusive, or at worst it impinged on particularly quiet sections of certain tracks (Laura Marling springs to mind).

I ended up getting my money back after realizing that the humming is just a part of the package.
Now I have bought a Roksan Kandy K2 instead - more expensive, no humming + an even lovelier sound!
I have kept my Rega DAC, since it matches the Kandy K2 nicely.
Next is a speaker upgrade to match the qualities of the Kandy K2 - leaning towards Epos M16i floorstanders.

I also own a Rega Brio-R and I can also hear a tiny bit of humming when the volume is at 0. I don't sit very close to the speakers, so it is not a problem for me. When turning up the volume using the remote, the humming gets louder.
This is a minus, but it is no problem at all. I am very pleased with this amp!
I have a one week old Brio R with buzzing and humming. I can hear it from anywhere in the room and it is especially noticeable at night when everything else is quiet. It also swithces to Input 2 everytime I turn it on. I thought this was some sort of feature.
I have a 2 month old Brio R and have heard no humming whatsoever and very pleased with the sound!
Regarding input 2, this must be feature as when I turn mine on it switches to the last input used which is input from my DAC

Humming,buzzing through the speakers is just part of the Brio-R package,I'm afraid. The more sensitive your speakers the worse it will probably be. It sounds like I've got a wasps nest inside my MA RX1's with the Brio-R connected.

Re-read my experience and have it replaced.
My Brio R does not and has never buzzed or hummed, I've even turned up the volume full (without any source) and can hear nothing. I really don't think it's acceptable to have it buzzing and if it were me I would get it changed especially as its a £500 amp!
a humming from one speaker and lack of standby made me sold mine.

Are you still using the Brio-R? I notice you no longer have it on your signature. Given the fact that your replacement seemed to tick all the right boxes, it just piqued my curiosity. Please don't think me rude for asking.
A series of very nasty circumstances forced it's sale, and equally sadly my "stop-gap" Alpha doesn't tick many boxes at all.
Have any of you guys considered running a di-magnatising tone through the amp. You can get it on those disc laser cleaners with set-up and diagnostic, it may be worth trying.
I was shocked at the response letter suggesting 'cheaper' brands don't hiss but 'quality' kit does, I'd have to tell the author of that letter to role that up and shove it were the sun don't shine as for the 'most speakers don't play 50hz'....hilarious
I took my Brio R back to the local dealer this weekend. The sales guy could hear something was wrong but seemed to be saying it wasn't too bad. He got their repair/tech guy to come have a look. He started messing with the volume among other things and I told him the volumed doesn't affect the buzz. He immediatly said "Bad power supply." They ordered a new one for me so I hope the new one works. But they both agreed that I had a bad unit.
I hope you get it sorted!
As previous posts have mentioned, it's the design, I don't buy it because my Brio R does not and has never buzzed or hummed but it has given me many hours of enjoyment.
Its a cracking little amp and I couldn't warrant the extra for a Nait 5i or Kandy when I auditioned it.
The Brio R is a cracking amp and if you get a good one it is a good buy. However, I personally think some of these humming issues are totally unacceptable on a £500 amp irrespective of whether even more expensive kit suffers in the same way. My £300 NAD doesn't hum or make any extraneous noise at all and, to be perfectly honest, the performance gap between it and the Rega is pretty tiny in my experience so I certainly wouldn't accept added noise for the extra £200. My advice to anyone suffering from these issues is to go back to the supplying dealer and insist on repair or replacement. Consumers shouldn't have to put up with these sorts of issues on expensive kit.
