Things to Know
Fosi Audio SK01
- ⚠Built-in battery is unnecessary for a desktop unit and will eventually degrade/fail.
- ⚠Input is limited to a single 3.5mm jack (no RCA inputs without adapter).
- ⚠Form factor is tall and narrow, making it easy to tip over when heavy cables are attached.
Topping L70
- ⚠Rear panel is extremely crowded; thick XLR cables can be difficult to unplug.
- ⚠The 'clicking' sound of the volume relays is audible inside the chassis when changing volume (normal but surprising to new users).
- ⚠Display menu system is somewhat cryptic (abbreviations like 'H-G' for High Gain).
