Who It's For

Vinyl systems and HiFi front-ends that need clean gain, source switching, or tone shaping before a power amp. The SK01 fits turntable setups, desktop preamp chains, and living-room systems that already have passive speakers and a Class-D amp.

Setup & Connectivity

On the desk or in a living-room rack, the SK01 is easy to integrate: expect headphone outputs for IEMs and over-ear cans, phono-ready or vinyl-friendly I/O for turntable chains. Review the photos and feature list on this page, then buy through Amazon when you are ready — the same Fosi Audio hardware sold on the official store.
