Might be living overseas, electronics adaptability

Hello,

I came from Europe this summer with my system. I really had a very well balanced installation, I was most happy with. So I bought a good step Down transformer, plugged everything, let it heat a few hours.

the result was… howful! Blurry bass and medium, yelling high etc but no power

tried another transformer, no better.

i think this is because the power signal is so processed due to the difference of 50/60Hz that it is unstable and when you need real power it does not have enough inside to give the dynamism and let the system sing. What do you think?

I called and wrote to some major local brands and audiophile shops, most told me it was either expansive or they don’t do it even for a 10k amplifier… 
so I kept my two vaccum stages in their box and bought the one I have now in my system now which can be switched manually. 
there was no issue with my TD, the power works with both voltages. It is never a problem when the output is DC. 

have a great night!

generally, a quality transformer should work. 

The problem is, most transformers are no name Chinese products and you won't know until you try. There is no VWs, Audis and Porsches of transformers.

Also, return policies aren't generous in Europe like they are in the US and even if you can take them back, the store won't pay for your amp]s damages. 

I would contact NAD to be a 100%.

I’ve made the move you are considering. USA to Portugal. Keep in mind that any electrical item with a motor or heating element are poor candidates for voltage converters.  EU is 50 cycle vs 60 cycle US standard. I contacted Hegel about my H390. They recommended not using a converter due to current draw. A €60 visit to a Lisbon Hegel dealer got the conversion done. For my Rega P6 , a European wall wart took care of the problem. That worked because its motor is DC and the wart provides the correct power. I sold my cd player due to the ac motor problem mentioned earlier.
