Is the new one still silent at home ?

Noisy transformers can be caused by less than perfect mains (harmonics or slight "DC" offset).

new m6i is very quiet you can hear mains transformer if you put your ear right up against it .Before you could it hear about 3 meters away and I am sure new one sounds better so right know I am as happy Larry:cheer:

I have found that recently since I moved house the sound on my hifi has changed dramatically. I run quad ESL63s with quad amps and found that my new house the hifi sounded much warmer and less clinical. After much deliberation and investigation (firstly into room acoustics) I doscovered that my old electricity supply was from a nucleur power station (Sellafield) and my new from a coal station.
