Bengineer Posted April 11, 2021 Share Posted April 11, 2021 I just got one of those sub $200 Thor poweboards, 8 sockets. In a quiet room you can hear it. That electronic squeal, like a very high frequency constant noise. Is this normal for these things? Does it eventually go away? Should I just aim for something better, Isotek one or something else?

TDX Posted April 11, 2021 Share Posted April 11, 2021 If you remove everything plugged to it, is there still any noises? Link to comment Share on other sites More sharing options...
muon* Posted April 11, 2021 Share Posted April 11, 2021 I have a Thor Smartfilter 8 at my feet now at my computer, makes no noise, maybe return for another unit. BTW, many including myself have found that while the Thor boards work OK for most audio components they are not good for amps, they tend to limit dynamics with amps plugged into them. I use some smaller ones daisy chained for my CD player but have my amp plugged into a non filtered board. 2 Link to comment Share on other sites More sharing options...

barbz127 Posted April 11, 2021 Share Posted April 11, 2021 I have two 4 port boards that have done this from new. 18 months later they still do it. I've just moved the noisy boards out to the tv where I can't hear it. Link to comment Share on other sites More sharing options...
aussievintage Posted April 11, 2021 Share Posted April 11, 2021 Send it back and just get a normal powerboard. Spend your money on music you like. You'll be much happier. 4 Link to comment Share on other sites More sharing options...

I'll just find another spot for it. Why odd? We should not put up with faulty products. Shoddy manufacturing and poor quality control is riding on the shoulders of complacency of consumers. If you bought it this way with no warranty or opportunity for return, then you should be happy to bin it, or re-deploy it, when it fails to provide the expected functionality - as you say you will. 3 Link to comment Share on other sites More sharing options...
muon* Posted April 11, 2021 Share Posted April 11, 2021 (edited) They make a very noticeable positive audible difference with my CD Player plugged into them. I would not get rid of them, just return for non faulty one and use it for anything except amps. Edit: Ah! @Bengineer just saw it is a second hand unit.

Bengineer Posted April 11, 2021 Author Share Posted April 11, 2021 *new* but bought here so no warranty don't think. Bank 1 is fine. I'll just use it for the two speakers, DAC/amp combo and the PC or something. Just waste of 4 ports. Link to comment Share on other sites More sharing options...

Just remember, that is only your own personal experience, coupled with anecdotal "evidence" from others. I think I remember you are anti DBT etc (apologies if otherwise), so I will leave it at that.

I am really glad you guys can have a laugh about it. Truth is, I nearly didn't post that comment - worried about yet another brawl starting. 1 Link to comment Share on other sites More sharing options...

deafenears Posted April 12, 2021 Share Posted April 12, 2021 Maybe contact Thor Technologies and see if it's a known thing or if they think it's faulty. Or just put your headphones on, or IEM, or crank up the speakers so you won't hear it Link to comment Share on other sites More sharing options...

Thinking it may be one of your components plugged into Bank2 that is somehow generating the noise. 1 Link to comment Share on other sites More sharing options...

075Congo Posted April 15, 2021 Share Posted April 15, 2021 Just reading the Thor Technologies website re warranty. Even if its a second-hand unit it would be worthwhile seeing what they say is going on. From a PR point of view you would think they would not be too keen on a SNA discussion on their products worth. Their website puts them forward as the real deal. Cheers 1 Link to comment Share on other sites More sharing options...
075Congo Posted April 15, 2021 Share Posted April 15, 2021 Contact Nick Forster-Jones their National Sales Manager on 1300 766 140. Maybe he will offer some technical support. I would mention that you have been seeking the advice of 'fellow Stereonet members" on this forum. Be interesting to see what reaction you get.
