Dzień dobry,
Od tygodnia jestem posiadaczem RS151. Czy to normalne, że słychać buczenie transformatora?
Pozdrawiam
No. You should return the unit.
No.
Could be a grounding loop problem.
Simplest thing is to check all of your connections in all of your gear including speaker cables and connections.
Buczenie dotyczy tylko samego RS151. We wzmacniaczu MICHI X3S2 oraz kolumnach B&W 703 S3 problem ten nie występuje.
So your setup minus the RS151 doesn’t hum… but when you add it… it does?
Check the outlets and move them around to see if that stops it… Also the cables connecting the RS151 to the amp.
Are you using XLR or are you using RCA?
If you have the RS151 standing by itself not connected to anything… do you hear an audible hum from the unit?
Since you just got it… contact the local dealer / distributor to see what they say.
Po odłączeniu wszystkich przewodów nadal słychać transformator. Po podłączeniu RS151 u mojego znajomego też słychać buczenie. Nie jest ono bardo głośne ale jednak jest.
If the device is just sitting there plugged in with nothing connected and you can hear it hum… and you tried this at two different locations… then there’s a likelihood that there may be something wrong with the unit.
What does your local dealer say?
Do you have any surge protectors or any sort of power conditioners that you can use?
RS151 podłączone jest pod AudioQuest Niagara 1200.
So there is a power filter in front of the unit…
I’d say contact your dealer and the local distributor on this…
Good luck.
You talk so proudly of the 151 yet here we are another similar issue to resolve… Just maybe there is an issue with the 151
You’ve made comment regarding my issue but you offered me zero resolve… 
Steve,
I’m not Rose so I can’t help, nor can I diagnose a problem over emails or what not.
Most of the time… its user error. You had to send your kit back to Korea for them to try and solve the issue.
I am not talking so proudly of the 151.
What I have said in other threads is that most people aren’t having these issues.
I understand your frustration.
Pawiz1 described a problem which could have been a simple issue of a grounding loop.
When I didn’t have one of my speakers connected to cables… it made the Rel Subwoofer hum. It went away as soon as everything was connected. A bad cable somewhere else in the loop could have the same effect. In another forum… helping a guy track down an issue. Where it was an interconnect cable.
Just trying to help rather than say “go return it and come here to be-itch”.
OK?
The whole and soul purpose of the forum is to assist and share… Ideas …
Not to deny others there intent to resolve an issue…
Critique to insult is disturbing at best …
But It’s interesting to see other take charge…lol
Me Well a bit deep and aging… Not a good combo.lol
So my interest are simple Two speakers a preamp/ transport streaming and an amp…You would be amazed as to the results… So to sum … To have played with music and Good equipment for many years… Putting the Rose to a classic and powerful and dynamic Pure class A…amp was a wonderful experience…
Honestly I was never optimistic about The Rose.
Read a few horror stories…
My initial thought after listening was a noticable difference
From multiple products all having limitations.
So after all said and done.
If it doesn’t work out oh well.
After tons of research there are many that interest me…
Music should only be a peaceful moment of your day !
That’s true.
I got the RS520 because it was on sale for a price that was too good to pass up.
The reviews were good and it had the power.
There is nothing wrong about being down on a product, or critical…
But it shouldn’t just be bashing the product for the sake of bashing.
Its weird what happened w the Krell.
But I don’t know if that’s Rose’s fault or Krell’s … or just a bad combination.
I know definitely that The Krell is not the issue…
I Use a CNX100 as a preamp and steamer going on Three months flawlessly… It’s a great combo as well
The Speakers do the combo well just a little short on depth and low dynamics.
Again the Rose /Krell combo started off Great!
And looking forward to it’s return…
It’s hard to believe that it just stopped working …
Software upgrade more than likely generated the the current status… Only do to it crashing during the download.
So the issue I have here is speculation…
I’m living it and Rose is like " I’ll get to ya next month"
Lol… I said the day I did the firmware update kept saying don’t do it, don’t do it! Lol
The Rose Growth and lack of US support just snowballed!
And I’m at bay !
Sorry for my rant…
And good for you and your luck!
Enjoy the music!
We apologize for the inconvenience.

Cześć ! Mam 151 od ponad 6 miesięcy . To nie jest normalne. Jeśli masz gwarancję odstaw sprzęt do sprzedawcy i reklamuj.
Transformers hum when there is DC in the mains. It is very common reason but not the only one. Quick solution - take the unit someplace else, office, school, shop, wherever, not close to home and check the hum. If the hum stays, it’s faulty transformer. If the hum disappears there is a problem with your mains

Brzęczenie słyszalne jest z odległości mniejszej niż 1m. Nie jest ono zbyt głośne. Testowałem RS151 w innej lokalizacji i zachowuje się tak samo.
