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.  

I totally agree, I'm afraid. I bought a Brio-R last year and enjoyed it but the buzz was a concern, though not noticeable to me from across the room.

Now sold and currently using the rather fine Caspian M2 - until (possibly) Naim upgrade their integrateds.

RE: Humming ,buzzing Brio r

I have the dac which I took back for a buzzing issue but the dealer tested for audio hum and this is not an audio hum, it's powerpack hum, I decided to live with it.

Now got the apollo-r and that hums too, both units in unison make a pretty loud hum.

The dac will now be out of warranty so I have left that too late I guess, but the apollo-r I have only had for two weeks or so, just love the sound of this kit but can't live with both of them humming, like opthers I like to leave the kit on 24/7.

Worthy of note is I have a brio 3 on the same mains and no hum what so ever, so it must be I think a problem with using smaller cases and the powerpacks untilised to make that possible.

It's a shame you can't phone rega direct as this would really be such a good thing, in my experience the dealers are never so great in sorting this kind of thing out.

NO buzzing on any my Rega gear.

If you look hard enough it's not difficult to get Regas number, they are very helpful and it's an unwritten given that they will honour warranty for life

RE: Humming ,buzzing Brio r

That's a quick reply Smile  thanks

 

I will look harder for the number, just had standard 50hz reply from dealer and pointed him to this thread and asked if he will speak to them.

 

As pointed out above it' not like it's cheap gear, although as we know it is excellent value for money, will keep you posted.

RE: Humming ,buzzing Brio r

Tube amps have some hum and hiss. The brio is solid state but the circuit design of the Brio has some hum and hiss, It is also more prone to RFI. If you can not deal with hum and hiss in any measure you might not want to buy a Brio. The degree of hum/hiss/buzz will vary according to location of amp. It's a pretty well established fact that the Brio does this. And for the record the one I had did too (a brio 3). The noise of the brio could likely be eliminated by using more negative feedback in the circuit, but of course would be detrimental to the sound quality. Basically Rega probably decided The Brio sounds best with a bit of hum. If you still want to get Rega gear, the Mira and Elicit do not have the hum of the brio. If you want totally no noise coming from the amp, and that is your main objective,  buy a Bryston.

RE: Humming ,buzzing Brio r

just replace the main cable with something better ( like I did) and hum will be no more.

Looks Rega is very sensitive to any RFI frequency and original main cabel works well as an aerial Smile

I spend £65 on main and can't hear any hum. 

try to play with positioning as well might help without investing any money.
