The S-05XE is an accomplished stereo power amplifier from Esoteric, built with a versatile BTL bridging mode and an extraordinary damping factor. The S-05XE brings Esoteric's meticulous engineering to dedicated stereo power amplification.
Key specs that matter
Input impedance is 10,000 ohms on both balanced and single-ended connections. Output power is 2 x 30W into 8 ohms, rising to 2 x 60W into 4 ohms. Gain is 34.5dB in BTL bridged-mono mode. Frequency response spans a wide 5Hz to 100,000Hz within plus-or-minus 3dB. Signal-to-noise ratio is 104dB, with total harmonic distortion plus noise at 0.007% at 100% global feedback. Damping factor is an extraordinary 500. At 445 x 191 x 443mm and 25.6kg, the S-05XE represents a substantial power amplifier commitment reflecting Esoteric's meticulous engineering standards.
Sound and use context
Expect exceptionally clean, tightly controlled amplification reflecting the extraordinary 500 damping factor, with the versatile BTL bridging mode allowing configuration as a mono amplifier for serious dynamic scale.
Pairing
The versatile BTL bridging mode lets two S-05XE units be configured as substantial monoblocks for demanding loudspeaker loads.
Alternatives
Esoteric's own F-01 and F-02 integrated amplifiers offer alternatives combining preamplification and power amplification in one chassis.
