For the not so technically minded that means it's a really good stable amplifier unit when the speakers demand a lot of power to drive bass without distortion or treble with detail and finesse and it will cope with inefficient speakers. The standing temperature is lower than that encountered in Class A series designs because it's a Class AB design.

It occupies a niche in audio systems for the person that really loves big dynamic sound like movies, orchestral pieces and of course playing music loud!

The physical construction of the SB-301 is based on the SA series designs so it has the same distinctive aesthetic as the Class A products and indeed much of the electronics topology is derived from that Class A history

This amplifier delivers all the dynamics, finesse and transparency that Plinius is renowned for. Like all Plinius products it is very reliable and will rise to the challenge of difficult operating conditions time and time again.
