### ⭐⭐⭐⭐ Recommend for people to start their audiophile journey
*by R***P on 29 April 2025*

the v3 is really good for the base. It is also ideal if Fosi comes up with a hybrid amp with tubes for the Mids and Highs or another tube amp with the same gain as v3. The Volume knob is smooth, but a bit too smooth, and I think it would be best to have the volume marker in flourescent for better visibility. The binding posts could have been better organized. Overall a good class D amp.
