A brief update, still loving the DC filament upgrade, if you are considering it just do it. I heard no downside with it, just silence at the speaker.
The Elrogs are sounding great. This is the tube I will be running assuming I can get them.
BTW, for those of you running digital systems, take a look at Roon. I did and I am going to stay with it. Well organized, great additional info available regarding artist, album, influences, etc., it's integration with Tidal is outstanding, the combo puts a huge segment of the musical universe at your fingertips via a great UI. I am really enjoying it, certainly worth a 14 day free trial.
Best,
Ed
