I have a pair of NC-400 based mono kit (built by own) , Ucd3xMP amplifiers for my own.
And I imported some NCore based amplifier for my friends.
This PA-S250NC is excellent!
- rigid body makes this well frequency reproduction balance
though not easy to open top plate... I had to struggle with many screws...
This amplifier may use uniiversal amp chassi but better than most of amps in this price class or upper class.
- Well considered simple construction
Simple and it seems easy to maintain.
- Good sound from initial
