Burson Soloist 3X GT, Burson Super Charger 5A, Gustard X26 Pro, HiFiMAN HE1000 V2, Singxer SU-6

The Soloist 3X GT with the Super Charger 5A is my first Burson product. I never would have heard of it if it were not for Sandu Vitalie’s review that prompted me to begin doing more research into Burson products and its competitors. This amp with its charger is a wonderful device that will remain in my chain of sound for a very long time.
