Hi to alla of you from my new account. Just wanted to say I am back with a complimentary Roon account from my employer and thus will have this new profile. My former; Lars-Göran_Andersson is buried and will not appear again as of now. Just to let you know, I am working as a R&D engineer at Jorma Audio, Sweden, designing mains filter, cabels and do research about various ground noise issues in hifi systems. Just to let you know about any bias that might be appearent
Welcome back, we await the measurements and facts you discover about these issues.
