The excessive heat given off by the Uptone EtherREGEN was one of the main reasons that I didn’t want to implement it into my system. I use a passive Network Acoustics ENO Streaming System that is a dedicated RFI filter that helps to feed my music server a cleaner signal that comes from my router through two network switches. RFI/EMI and heat can really affect your music enjoyment experience if not properly addressed in your listening chain.
