A pair of ECC83 double-triodes handles the input stage and a pair of 6H30 double-triodes runs the driver stage, both in pure Class A totem-pole configuration, before a Class AB Hexfet output stage with four complementary pairs per channel drives the speakers. Unison Research developed two circuit standards, a two-stage version for lower-powered amplifiers and a three-stage version for higher output, and the Unico 150 uses the three-stage circuit.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch5 dir=\"ltr\"\u003e\u003cspan\u003e150 Watts, Dual Mono\u003c\/span\u003e\u003c\/h5\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eRated at 150 watts per channel into 8 ohms and 220 watts into 4 ohms, the Unico 150 is Unison Research's most powerful amplifier and is built as a dual-mono design, so each channel runs its own amplification with minimal interaction between left and right. That combination of valve front end and high-current Hexfet output is what lets the amplifier hold its composure on large or demanding loudspeakers where smaller hybrids run out of headroom.\u003c\/span\u003e\u003c\/p\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0555\/5073\/8528\/files\/unico-150-front-silver.jpg?v=1780912342\" alt=\"Unison Research Unico 150 integrated amplifier front panel in silver\" style=\"width:100%;max-width:1000px;height:auto;border-radius:12px;margin:16px 0;\"\u003e\n\u003ch5 dir=\"ltr\"\u003e\u003cspan\u003eZero Global Feedback\u003c\/span\u003e\u003c\/h5\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe Unico 150 applies no global negative feedback, relying instead on 16dB of local feedback within the circuit. Designers use global feedback to lower distortion measurements, but many listeners feel it costs the music some life and immediacy. By keeping feedback local, Unison Research aims for a more open and natural presentation, and the amplifier still holds output resistance below 0.4 ohms across the audio band for firm control of the loudspeaker.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch5 dir=\"ltr\"\u003e\u003cspan\u003eBalanced, Single-Ended, and Bypass Inputs\u003c\/span\u003e\u003c\/h5\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eConnectivity covers six line-level inputs: three unbalanced RCA, two balanced XLR pairs, and one unbalanced bypass input that runs at fixed gain for slotting the amplifier into a home-theater system.
