Either I have been blessed with clean mains or it's not normal for amps to buzz  or hum audibly (whether audible through the casing, or through the speakers, or both).

 

 

 

Same for me, regardless of the make. Over a 30-odd year period I've never had a hi-fi component that hummed or buzzed. No doubt the transformers do make a noise... shouldn't be audible, though, unless you stick your head inside the casing.

Most don't, however in certain circumstances even your 'perfect' Supernait could hum, different distortion on your mains might exite resonances that are not being exited at the present time.

I have never said my Supernait is perfect, 

What is your problem?

These issue are quite rare but when they do occur they can be a begger to sort out.

Over the years the biggest issues were caused by Naim amplifiers and PSUs. If you are lucky just swapping one component for a nominally identical one will do the trick but if this also hums then you are in trouble.

I have seen multi thousand pound Naim systems that had to be refunded over this issue, they simple could not be made to be quiet in that environment.

I know that naim worked very hard to overcome this issue, changing spec and manufactures a number of times.

If you do not have this issue then it can be hard to understand how it can happen, but it does and it is, mostly, not defective equipment, just unfortunate circumstances.

I was refering to the fact that you clearly stated that your amplifier does not hum at all, it is therefore 'perfect, in that respect.

Nothing else meant or implied.

RE: Rega have let me down again!

Ok spoke to Cymbiosis they acknowledge it should not be humming after speaking to Rega - just need to take it in now so they can hear the hum! Legally all they have to do is repair or replace with new I think

By shear nature of a transformer, it will emit some noise. But I've not heard any audible hums or buzzes through the speakers or close to the case that's audible, apart from the Leema but that was only thru headphones.

Of course, years ago, when I chopped and changed carts or made my own interconnects, the earthing would on occasions be a little iffy.

If I'd spent £1600 on an amp and it hummed it'd lob it back... thru the window (probably).

I hope that the issue is easily duplicated in the shop.

It can be rather embarrasing to find that the different mains conditions in the shop do not exite the resonances and it is perfectly quiet.

Do not let that throw you if that is the case, just say that in your conditions the hum is very audible but this was not the case with your previous unit. 

I have experienced this many times and I would be very surprised if your dealer is unfamiliar with the issue.

A DC filter maybe the answer.

Understandable but unfair.

It is pretty unlikely that a reputable compant would allow an amplifier with a mechanical hum/buzz that can be heard 3m away to get through QC.

It is possible that damage of one sort or another has occurred in transit, but that too is quite rare.

As explained above it is the effects of your (distorted) mains on that particular transformer (model or individual item) that is causing the issue.

You would probably be making a better point by lobbing it through the window of you electricity supplier....!

Make a video of the amp whilst it's buzzing (assuming you have a digital camera or smart phone that can do videos). If it's close enough, the buzzing should be on the soundtrack. (No problem if you can hear it from three metres away whilst music is playing.)

if the dealer can't replicate it in the shop then at least you have the evidence.

RE: Rega have let me down again!

Ditch the lot and mate a Marantz 610 with a decent phono stage. You know you want to.
(That was more tongue-in-cheek than a genuine suggestion, but even so the Japs do seem to be more on top of quality control.)

I've always listened to budget amps (Rotel, Marantz, Pioneer, NAD)..............I've never experienced any humming at all.

 

 

I'm toying with the idea of an upgrade of my Denon M-38 to a budget amp - NAD (316/326BEE0) or Marantz (PM6005). At the budget level, is there any significant difference between them. I only listen to Classical Music, and will be upgrading my CD player, too.

RE: Rega have let me down again!

Hi Steve,

 

Sorry for the delay in replying I am in the USA and time differences got in the way.

Sincere apologies for the difficulties you are suffering with the Elicit R and the possibility of humming from the transformer.

I have contacted Cymbiosis by mail and have said that if the unit exhibits the same issues in their store then we will replace the unit without question, if the unit does not present the same problems then we and they will work with you to eradicate the problem in your system and room and ensure a completely satsisfactory conclusion.

 

If you could contact me directly by e mail when a solution is found I would be very grateful,

 

Paul Darwin

RE: Rega have let me down again!

Well I am able to get a refund, however my heart is telling me one thing and my head another! I really love the sound of the Elicit and I just don't have the time to go auditioning amps again,, I thought I had found my perfect amp! I guess most of you will urge me to bin Rega but I am debating to give another Elicit R another shot!

The thing that put me off the Naim is that the volume control is not a usable as the Elicit - I dunno lots to think about and yes there is plenty of competition in around the £1500 mark.

Electrocompaimnet look nice
