Hello. This is my first post since moving back to the U.S. I have a RSP 1570 and RMB 1575 that I bought in Europe and had them converted from 240v to 120v when I moved back stateside by B&W Group. Before conversion, my normal listening volume was around 45, after the conversion I have to turn it up around 60 to get the same listening pleasure. I talked to B&W and they said it check out on the bench but I know for a fact that it's not the same. any thoughts.:cry:

Did you move the entire house and furniture from Europe too?
Speaker placement, room layout, room treatment, where you sit, etc can all effect your perceived volume.
I can't rule out efficiency changes from running at a different voltage or possible amp adjustments to bring it back to spec since it was on the bench, but if it still sounds good I wouldn't be concerned.

yep.. moved the entire house and the dogs... the equipment was in a space that was open all the way to the second floor with no walls, it now sits in a dedicated room above the garage and still sounds good but I just have to turn the volume up considerably to get the same sonic experience that I had at 240v. thanks Kevin.....Comment

could it be that the new environment is simply more energy absorptive ?Comment

yes it could be but from 45db to 60db?? the house in Europe was built like a fortress., no prefab like here in the U.S. all concrete floors solid wood doors. note sure if listening at those levels (60-65) is a strain on the amp or not. the speakers should be o.k. B&W 805D.Comment

The volume level on Rotel is not a db scale and not linear from what I've seen. My normal listening is 65, and 75 is really loud.

60 - 64 is where it sounds good so i guess it's o.k. thanks for the insight.

Here too. Small room. Sonus Faber Olympica II (Marantz MM7055) and Rotel RSp-1572. (i already had 1570) The pleasant volume is around 60-70 max! Now iam listening a cd at 56.
My unit is 220v and here in my city is 120v, and i am using a transformer voltage.Comment

I have gathering dust at my house an APC Matrix-UPS 5000, a 4.7kVA UPS that puts out very clean sine wave AC in normal operation. (When inverting from batteries to AC, the wave form is nothing to write home about: okay for computers but not what you would want to use for audio.)

Does anyone know how I can get a 110-120V 60Hz power amp to work on 220-240V 50Hz ?
I can purchase a NAD S250 (5x125W) power amp at a ridiculous price, but the problem is that it is a US version and I need to get it to work on our local power supply.
The local NAD importer is not able... -
This is just a "utility" thread to appraise folks that mostly hang out in Mission Possible about bench testing of commercial components that may or may not be of interest, posted in "Audio Hideout" and "Digital Audio".
A few components have been tested and... -
I've read some of the manuals for some of the Rotel equipent I might be intrested in. And I've noticed this.
The manuals for the power amplifier units (RB and RMB) states:
"Note: Should you move your RB-1080
amplifier to another country, it is possible

Hi to all,
I am thinking about purchasing a RDC-7 from the USA and having it shipped back to Australia where we have 240V/50HZ.
My question is, is it possible to change the voltage with one of these units, and if so how difficult would it be.
If not, I guess...
