As of yesterday I have four Synergistic Research Purple fuses in my system. Unfortunately I can't upgrade my Oppo BDP105D ;^(
Supernait 3, Naim nDAC,Teddy Pardo XPS and Teddy Pardo TeddyCap SE.
The Oranges are very good as well but I prefer the Purples in my system. The Oranges have killer 3D soundstage imaging but the Purple's are more dynamic in my system.
I also have over 325 hours burn in on the Furutech GTX-D Gold receptical. It has a very consistent and coherent neutral sound. Clean clear extended high frequencies. Also highly recommended.
I purchased upgrades from Chris VenHaus of VH Audio. Excellent, courteous and knowledgeable customer service. FAST shipping too.
