{"product_id":"trilogy-921-integrated-amplifier","title":"Trilogy 921 Integrated Amplifier","description":"\u003cp\u003eThe 921 is Trilogy's solid-state integrated amplifier, launched in 2023 and described by the company as its \"entry level\" model. Rather than build a preamplifier and a separate power amplifier into one chassis, Trilogy chose a single, ultra linear gain stage that does all the voltage gain necessary, connected directly to a compound output stage reminiscent of the larger Trilogy power amplifiers and using the same Japanese bipolar devices.\u003c\/p\u003e\u003cp\u003eThe topology has extremely high bandwidth, low distortion and very good loudspeaker control with only a tiny amount of overall shunt feedback. Rectification and the smoothing capacitor bank sit on each of the left and right amplifier modules, and a separate winding on the mains transformer feeds them independently. To keep signal and current paths short and minimise interaction between them, the layout is stacked: the voltage gain cell sits above the main circuit board that carries the output stage and power supply.\u003c\/p\u003e\u003cp\u003eRated output is 75 watts per channel into a recommended load of 3 to 16 ohms, from five pairs of RCA inputs. Frequency response runs 5 Hz to 100 kHz within half a decibel. The 921 is phase inverting — worth noting when setting up a system, since absolute phase can be corrected at the loudspeaker connections. \u003cem\u003eThe Ear\u003c\/em\u003e made it an Editor's Choice in January 2024.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated power:\u003c\/strong\u003e 75 watts per channel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended load impedance:\u003c\/strong\u003e 3–16 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTopology:\u003c\/strong\u003e solid state; single ultra linear gain stage into compound output stage; tiny amount of overall shunt feedback\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInputs:\u003c\/strong\u003e 5 pairs RCA phono sockets; input impedance 50 kohms; sensitivity 500 mV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 5 Hz – 100 kHz +\/- 0.5 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistortion:\u003c\/strong\u003e less than 1% A weighted at rated output into 8 ohms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e inverting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower consumption:\u003c\/strong\u003e 1 W standby \/ 300 W maximum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions \/ weight:\u003c\/strong\u003e 465 x 312 x 106 mm (465 x 350 x 106 mm including connectors) \/ 11 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Trilogy","offers":[{"title":"Natural","offer_id":49211047870683,"sku":null,"price":8500.0,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":49211047903451,"sku":null,"price":8500.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1363\/6553\/files\/Trilogy_2BAudio_2BApril_2B2023-1-EAR-AP_HF_2B_N.jpg?v=1788279882","url":"https:\/\/almaaudio.com\/products\/trilogy-921-integrated-amplifier","provider":"Alma Music and Audio","version":"1.0","type":"link"}
