bipet Posted May 30, 2020 Share Posted May 30, 2020 I ordered a Shanti in November 2019 along with a USBridge Signature. I have noticed that the Shanti has quite an audible hum. What is causing this hum and what are the implications? Is the unit faulty? Do all Shanti's suffer from a hum? Thanks Link to comment
reelben Posted May 30, 2020 Share Posted May 30, 2020 I have here two Shanti. There is here no hum. I am happy with it 🎶 Link to comment
bipet Posted May 30, 2020 Author Share Posted May 30, 2020 Thank you for the feedback @reelben, I suppose that suggests mine has an issue. @Allo, can you advise please? Link to comment
ambre Posted May 30, 2020 Share Posted May 30, 2020 Hi Rossco, does it generate a hum via the amp or does the Shanti is itself?

bipet Posted May 30, 2020 Author Share Posted May 30, 2020 Hi @ambre, its the Shanti itself rather than the amp. I was around the kit re-organising wires and I could hear a hum which I tracked down to the Shanti, more like a buzz if you get up close to it. Link to comment

alecm Posted June 1, 2020 Share Posted June 1, 2020 I have the same situation. Last month I hear hum from 30-50 cm. I thought it caused by the DC in 230v. Link to comment
bipet Posted June 1, 2020 Author Share Posted June 1, 2020 They it is normal and because of the transformer. Link to comment
Odie Posted June 18, 2020 Share Posted June 18, 2020 I have the same issue the shanti is humming not very loud but noticeable and yes it is the classic transformer noise. Is this really normal? With that price tag it shouldn't. @Audio_Allo i see you have recommended people with that problem to check something. What is it? Regards Odie Link to comment
bipet Posted June 18, 2020 Author Share Posted June 18, 2020 I have just changed hi-fi rack and its very very noticeable if you come close to it. Luckily with music on it becomes less of a problem. Link to comment

Odie Posted June 19, 2020 Share Posted June 19, 2020 To be honest I am sending the Shanti PSU back to the vendor. I don't think that an "audiophile" PSU should make any hear able noises. @Audio_Allo thank you for your support, I checked everything you suggested, I even took a look inside to see if there is something loose. @Allo would you please clarify if the Shanti power supply is virtually silent or is there a noticeable humming from the transformer by default. Thank you. Link to comment
allo.com Posted June 22, 2020 Share Posted June 22, 2020 Hello Odie Shanti has a very small hum as with any LPS . However we found that one unit in 90 (about) the hum is audible at more than 2 feet. For a few weeks now (at least 4) we are screening all Shantis and removing the ones that have a hum thats audible at 1-2 feet You probably bought one from a reseller , unfortunately those were not screened (but they are now) Link to comment

Ray99 Posted September 25, 2020 Share Posted September 25, 2020 Hi, I have just bought a Shanti and notice there is hum, it is noticable from about 4m away, on quiet music it is also noticable. Also I know someone else in the UK that has the same issue. Is it because the voltage in the UK is 240-250 volts, that is one theory. I have tried various things to reduce the hum but with only limited success. Is there anything else I can do before I send it back. Link to comment

SanjeevM Posted November 22, 2020 Share Posted November 22, 2020 Quote Buzzing sound from Shanti I had bought is just as it had been put for sale. It was silent then, but now I'm hearing a buzzing sound from the transformer. What is the remedy ? Link to comment

msaege Posted December 10, 2020 Share Posted December 10, 2020 Hi, I have just taken delivery of a Shanti, directly from Allo. I have the Shanti located in my listening room, approximately 1m / 3 ft from where I am seated. Since switching the Shanti on a few days ago, I observe a buzzing noise originating from it. What can I do to resolve this? Link to comment

SanjeevM Posted December 11, 2020 Share Posted December 11, 2020 Allo, since a lnumber of people are reporting buzzing of the PSU, why don't you change your transformer source. I've been using toroidal trafos since some time, and not a single one buzzes, at anytime. You seem to be using an EI core, which aren't very good. Link to comment
Ray99 Posted December 12, 2020 Share Posted December 12, 2020 Yes I think there is a problem with the transformer. My first unit buzzed from the start, this was replaced by Allo, at first there was only a slight buzz but after a few days it got louder, I can hear from 3m away but it’s not as bad as the first one. I could not be bothered to send the second one back to Allo in France, I have nothing else to use anyway. i think part of the problem is in The U.K. the voltage is higher than Europe, can be around 250 volts.

SanjeevM Posted December 13, 2020 Share Posted December 13, 2020 After buzzing for some time, the trafo heats up too. Link to comment
