Humming ,buzzing Brio r

Well never thought I would say this when listening to my hi-fi but silence is golden!

And a big thanks to Paul Darwin at Rega for getting this resolved so quickly. Fantastic customer service. 

Nice one 

Cheers mate, but I was still dreading plugging it in!

However, they had tested it before sendnig it out so I wasn't too concerned but was still sweating! lol

So, now you can switch it on without using sound barriers! Now it is a   Brio...

Haha Yeah you're right. I've had a really good session with it tonight with no anxieties for a change. 

It seems that exists to kinds of Brio's in the market. Those who have and those who not have the Buzz/humm i'll ask for the Brio that don't come with the extra, it should be cheaper...

further developments on this issue ...

When you first plug in a Brio-R you hear the rush of power filling the caps and a hum that subsides very quickly. At this point there is a light hum/buzz that I can hear with my ear about 6 inches from the speaker in a dead quiet room. There is also a low level transformer hum at the amp that you can barely hear with your ear right next to the amp in a dead quiet room.

I'm one picky SOB and if it were audible while I listened to music (at any volume including very low) I would be bothered. It isn't and I'm not. Every amp I've owned that has been able to communicate like the Brio-R has had this kind of noise in common. BTW I mentioned this somewhere in this thread.

The amp has been on without being turned off for a few weeks now I can tell you that besides the Sonneteer (a $2800 amp) I have not owned an amp that allows me into the musical discussion between artists like this one does. The Sonneteer Alabaster was able to do that with just a bit more resolution and I mean just a bit. I couldn't be more satisfied.
A little more info to follow up on what I said about Naim. The following is a quote from the Naim forum admin, Richard Dane;

"High performance toroids, as used by Naim, are very expensive but give unmatched sound performance. If they have a weakness, it's that they can buzz when there is pollution, excessive DC or interference on the mains. Ironically, it seems that the higher the quality of steel (and correspondingly the better sound performance), the more prone a toroid is to buzzing. Naim go to enormous lengths to try to ensure that any possible transformer buzz is minimised, but it's almost impossible to prevent it entirely without compromising the sound performance of the transformer. If you want to know more, ask your Naim dealer to arrange a tour of the Naim factory, where you can learn more about this. They have been working on this issue for as long as they have been fitting toroids to their equipment. I guess they will continue to do so until they find a higher performance alternative."

This has been done to death at the Naim forum and this is not a complete explanation (far more complete ones do exist on that forum) but it is simply a quote I ran across today from Richard. The Naim forum is one of the most tolerant of criticism I've seen from a manufacturer.

Exactly what I have now, not 12 feet!

Thank God I have a mediocre Marantz amp. It doesn't buzz, hiss or hum.

Has anybody seen the inside of that Brio-R? Isn't there a little bit of place left to shield the transformer?

Me too. TBH I hadn't bothered putting my ear that close to the speaker to see if I could hear a buzz, seemed a bit irrelevant.

I was thinking of buying a Brio R to replace my RA04 Se amp since it is supposed to have a good phono stage, but all this talk of humming on this thread has put me off. Perhaps squeezing all the electronics into such a small box was a bad move by Rega. I am still looking for an amp with a good phono input, for under £1000. Has anybody any ideas ? 

I have  .  The Sonneteer Campion: fine phonostage, extremely musical amp and under 1000,- !

And mine is still not humming or buzzing even after 11 years....

yeah, the Brio R Seriously, this thread about humming and buzzing is making the whole issue bigger than it actuallly is. I never ever heard it in mine, except after reading this thread and putting my ear to the speaker. And yes, I too have a 'small hum'. But a Naim has it too, and the explanation is perfectly viable. 

But this all doesn't matter if you start playing music. And each and every time I do that the Brio R makes me smile. Big time!

I agree, but it's also fair to say that Sizzers first amp had a fault.

I don't care if Brio r hums or buzzz I'm going to buy it anyway!!!!!!!! Just wanted to share what is happening in other forums and other brands, which in my opinion Naim is so believable (if not more) than Rega, and has the same little problem! this makes them so special and magnificent and is related to the technique cofiguration! The Rega Brio R is a bestseller, and in the future no doubt that will be a collectible item!
