what I noticed at the shop was that the humm was not so loud maybe because they are using expensive main blocks and cables . and WHF maybe keep original power cable for review but the rest is high quality block .......
but you are absolutely right for 500 £ it should not be there . I used to have speakers on my pc desktop and once I noticed that hummbuzz I couldn't get it out of my head , pretty annoying
I Mac , Leema Elements amp-dac , Rega RS5 , Chord cables
Squeezebox touch ,Leema elements phono stage , Rega P3-24 , Ipad 4
I had a problem with mine humming see link
I ended up just keeping it as it was not noticeable when listening... but you can still hear it if you are reasonably close to the speaker
I've just purchased a Brio-R based on reviews in this publication and love the sound but after a few days, a faint but very audible buzz emerged. I find it pretty hard to imagine the company just letting that go but it appears they've comprised and hope that folks won't mind.
I do love the sound and am debating whether to just put up with the buzz or return it and go in another direction. It's so annoying, the pitch gets into my head and I end up obsessing. A great amp should at minimum run quietly.
Has anyone out there compared the new Marantz PM8004 vs Rega Brio-R? I'd be really curious and appreciate some feedback.
Thus far the buzz is definitely a buzz-killer...
I recently purchased a demo version of the Brio-R here in the States. I've had it for a couple of weeks with no buzzing or humming, but I'm definitely concerned. BTW, the little guy sounds terrific with my Salks--maybe a little under-powered, but still very nice.

Got the same problem.
In the end it was a SBT problem.
It is extremely sensitive fot strong magnetic fiels.
Have a realy powerfull amp (large coils).
On top of the amp there was always a buzz , humm, music terible.
I could not find a cause for the problem until i lifted the SBT from the amp during a song.
A take some precautionary masures and for now the prblems are solved....
Took me ages
No, it's humming.
I'm writing to Rega over the weekend citing this post amongst other things. This just shouldn't be happening with a £500 amp. It doesn't spoil the SQ but it is annoying that I have to keep remembering to switch it off and I have only had it for less than a day!
Hi Sizzers, any outcome on this? I'm about to buy one after a dem and although the demo unit was quiet, these stories have me a little converned.
ZP90 > SIA2-150 > SCM40
Buy the demo unit.
Marantz M-CR603 • Rega R3 loudspeakers • AirPlay • Apple iPad Mini • Apple iPhone 5 • Apple iMac • Apple AirPort Extreme 802.11N • Humax HDR-Fox T2 • Panasonic TX-L32D25B • Sony BDP-S390
It's the wrong colour.
I wrote to Rega last Monday detailing the problem and pointing them to this post here, and below is a copy of the relevant part of their initial reply:
The e mail quoted on the What HiFi Forum unfortunately is taken completely out of context.
It is a little curious, though, that the only mention that I have found of this problem is on these forums here as I've not come across it anywhere else. Anyway, following this I disconnected all the appliances (including boiler etc) and switched off all the circuits on the main fuse box with the exception of the 1st floor sockets (my system is set-up in my bedroom), plugged the amp directly in to the socket with the just the speakers connected and the hum was still there (I also tested this in a seperate room). I then carried out exactly the same procedure on the ground floor with exactly the same results. I reported this back to Rega and he took this for an opinion elsewhere, the outcome of which is that they are sending a new amplifier to the dealer which hopefully should already be there by now (checking on this later).
I would just like to say that Rega have been excellent and extremely efficient throughout. I sent the letter out last Monday and their initial reply was sent at 9-00PM (!) last Tuesday evening, and just after lunchtime the following day they informed me they would be sending out the new amp so a big "Thank You" to Rega.

Thank you, that goes some way to reucing my concerns. I have a very clean and constant mains supply so the Brio should have a good chance of being silent. You'll be the second to know if it's not.
Well I hope it's not going to be sods law when I take it back and it's silent!
My Marantz PM6003 and Pioneer A400 have never hummed, and nor did a NAD-whatever I had for a couple of days a while back. I'm not an electrician but I think I can safely say that it's not caused by any internal interference in the house.
Well so far so good.
So you've bought it then.
I'm sure my replacement tomorrow will be exactly the same. Enjoy!
Yes, I took a chance and rather nice it sounds too. Fingers crossed that you're lucky with your replacement.
Only "nice"? Even with the hum mine sounds better than that!
What have you got your's hooked up to.
