Please note that no factory warranty applies. The A-9150 is a meaningful step up from the A-9110, adding a built-in DAC, a dedicated MM\/MC phono circuit board, and Onkyo's proprietary Discrete SpectraModule to a power amplifier section that is already significantly refined over the entry-level models in the lineup. The Class AB amplifier delivers 30 watts per channel into 8 ohms and 60 watts into 4 ohms, powered by a customized high-output transformer and two large custom audio-grade capacitors feeding discrete output-stage transistors cooled by an aluminum heat sink — providing the high current delivery needed for confident, authoritative speaker control across dynamic and complex musical passages.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Discrete SpectraModule is the standout engineering achievement of the A-9150, boasting a slew rate of over 500V\/µs — far exceeding what standard IC chip-based circuits achieve — enabling flat linearity well into the megahertz range for full-bandwidth signal reproduction and a larger, more precisely defined soundstage. Digital sources are handled by an AKM 768kHz\/32-bit DAC with Onkyo's DIDRC (Dynamic Intermodulation Distortion Reduction Circuitry) filter, which eliminates ultra-high-frequency noise introduced during D\/A conversion before it can be amplified. Two optical and two coaxial digital inputs support PCM up to 24-bit\/192kHz. The dedicated MM\/MC phono circuit board features its own separate equalization stages served by a customized discrete head amplifier for MC signals, preserving the full depth and vitality of vinyl playback. Four gold-plated RCA line inputs, A\/B speaker switching with gold-plated binding posts, a front-panel headphone output, Direct mode, and a remote control complete the package.\u003c\/p\u003e","brand":"Onkyo","offers":[{"title":"Default Title","offer_id":45043273924661,"sku":null,"price":400.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/1704\/1461\/files\/6B02370A-5497-49B2-A59B-220204466356.jpg?v=1778271618","url":"https:\/\/alleliteaudio.com\/products\/onkyo-a-9150-used","provider":"All Elite Audio","version":"1.0","type":"link"}
