Hello Finn.  No hiss on phono at all?  Nothing?  I find your post of particular interest because you are using an Ortofon Cadenza Black, which not only is the same as my cartridge but it is also firmly in the low output MC category, which is most problematic with respect to hiss. 

So to be clear with the facts, with the phono input selected and the volume set to 0dB (obviously with no record actually playing), are you saying you can hear no hiss whatsoever?  Nothing, zero?

Also, if you would be happy to post, I would be interested in details of your cartridge settings and any other details of your configuration that might be relevant, such as inputs that you have not enabled, this kind of thing.  Thanks!

I'm pleased to read you are happy with the Pro upgrade by the way!

EDIT. Doh! I have just read your signature! I see that you are running an Ortofon Verto step up transformer. So that answers my question above, clearly the SUT mitigates the hiss issue, as you would expect. OK, but this leads me to a different question, can you provide any advice as to how the step up transformer impacts sound quality? Clearly it provides a stronger signal to the Devialet, which I'm thinking could well have a positive benefit, but of course you are also adding another component and cable into the chain, which is a negative. Have you ever done a comparison with and without the step up transformer, or perhaps you may have other observations?
