Congratulations ! It gets better with some burn in time...every time I listen to my 3 Vivaldi pieces...I am just happy. And I'm a vinyl bigot...The Vivaldi and a great SACD or DSD download can amaze. I haven't tried the upsampler yet either...but suspect I will soon. My dealer has a Scarlatti...all 4 pieces..and up sampling cds sounds better to me on his system.
Humm... Humm... I don't think so. After my experience with Paganini's 4 boxes (I sold the Upsampler after a couple of months), I could say that if you don't use computer (or another stuff) you don't need the Vivaldi Upsampler.
I have Siltech Double Crown for interconect and digital cables. The power cord is Nordost Odin. But for loudspeaker cables I use a regular electric cable, something like 40 dollars 5 meters, because IMO if the cooper is very good any speaker cable is good.
