The BorderPatrol S20 gives 18 Class A watts per channel from a parallel pair of single-ended 300B output valves and can drive a wide variety of loudspeakers.
The combination of extended bandwidth married to excellent dynamics and a magic midrange make the S20 both capable and musically communicative whilst the twin external power supply units give mono-block like sound staging and complete channel independence.
Clear, clean, fluid, extended, tonally rich and natural are all adjectives used to describe the performance of this fine amplifier.
Marrying finesse and sophistication to dynamics not usually found in SET amplifiers, the BorderPatrol S20 is a fine musical transportation device.
Recommended loudspeaker efficiency <89dB/watt for best performance.
The BorderPatrol S20 can be ordered with the EXD pack where copper chassis parts, cryo-treated transformers and upgraded components serve to further increase the resolution and improve the tonality of the amplifiers. It is also available with the EXS power supply units.
