Good evening all,
I've just completed a listening session and went to power the amplifiers down and thought "Hang on a moment those noisy ETC transformers don't sound quite so noisy".
Resorting to the same NIOSH app. the noise level was back down to circa 32dB(A) rather than the 35dB(A) they had been at.
A check on the myenergi app showed we were on mains electricity rather than supplied from the Tesla PW2.......... I've left this one amplifier powered up and will run a further check this time tomorrow night after it has had 24hrs to 'come up to temperature'.
Regards
Richard
