It looks great on the device
Surgical grade stainless steel housing and golden front cover, make up a reliable all-metal body.

All Pro Level Materials
The specially-made 6.35mm plug is made of high-purity copper, which is almost non-magnetic, and the surface is thickly galvanised with 24K gold. The soldering wire in the plug also uses high-purity OCC copper.

Upgrade to be non-lossy
The desktop amplifier device generally comes with a 6.35mm output port, and stocks with a common 3.5mm adapter. But the quality of the included adapter may not be that satisfying, so it's recommended to upgrade to a better adapter so as to avoid getting lossy soundn quality from your device.
