Our SSA-644 amplifier is the quintessential power amplifier. It is designed to have incredible transient response and dynamics while retaining a completely transparent character. It is capable of producing a wide, transparent, fully holographic soundstage. It is a terrific amplifier to use when testing components or cables due to it's incredibly revealing nature.
