Things to Know
Douk Audio T3 PLUS
- ⚠The 6A2 tubes are less common than the 5654W/6J1 family, making tube rolling slightly more difficult.
- ⚠No volume control; it is a fixed-gain phono stage.
- ⚠Included power supply is a basic switching wall wart that can introduce noise.
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.
