 Hello
        Recently bought the Gram Amp 2 SE and it's wonderful. A massive improvement on the NAD PP2 with my Rega/Cyrus setup. One thing I wonder about though is the constant high pitched sound coming from the power supply(the basic one). Is it supposed to do that? I can only hear it when no music is playing so not a problem. Is it to do with the green energy aspect?

Roy,

Welcome.

You are not the first to ask.

See this link to my reply to a very similar question.

BTW, the "low frequency" refers to lower than 30kHz which is still a high frequency - I'm sure you will understand the reply.
