The Esoteric S-05 witnessed the birth of an all-new stereo power amplifier, borrowing from the engineering techniques utilized in our flagship Grandioso M1X monoblock. The new S-05 – a class-A power amplifier thoroughly focused on delivering all of music’s unique tonal qualities from a more compact stereo configuration, embracing the philosophy of the Grandioso M1X: “minimal circuitry – maximum output”. Esoteric S-05 Features and Specifications: – Finely detailed Class-A sound with super dynamics – an Esoteric’s signature tone– Dual monaural construction in all stages including a current smoothing circuit for better channel separation– Esoteric’s proprietary “ES-Link Analog” delivers music signals with exceptional high power and fidelity.– High capacity bi-polar 3 parallel push/pull circuit that instantaneously responds to the music signal– 940VA large EI-core power transformer that responds to dynamic current supply changes with high speed– Large “Grandioso grade” custom capacitors on each channel (10,000µF × 4/ch)– BTL / Bi-amp mode switch for dual amplifier configuration Specifications: Speaker output Rated output power 30W + 30W (8Ω, Class-A)60W + 60W (4Ω)120W (BTL mode, 8Ω) Compatible Speaker Impedance 4Ω to 16Ω8Ω to 16Ω (BTL mode) Analog audio inputs ESL-A 1 pair XLR 1 pair RCA 1 pair General Power consumption 245W (210W at no signal) External dimensions (W×H×D) 445 × 191 × 444mm17-½” × 7-½” × 17-½” (including protrusions) Weight 30.7kg / 67-¾ lb Audio performance Frequency response 5Hz to 100kHz (+0dB, –3dB, 8Ω) S/N ratio 102dB (IHF-A, XLR) Total harmonic distortion 0.007% (1kHz, 8Ω, 30W) Compatible Speaker Impedance 4Ω to 16Ω8Ω to 16Ω (BTL mode) Gain 28.5dB
