GaN transistors switch at ultra-high speeds, \u003cb\u003eallowing CHORUS to generate an output signal virtually indistinguishable from the original analog waveform.\u003c\/b\u003e This directly translates to lower total harmonic distortion, wider audio bandwidth, and higher overall efficiency.\u003c\/p\u003e\u003cp\u003eUnlike conventional Class D amplifiers that rely on slower switching elements, the GaN power amplifier topology used in CHORUS achieves its performance without the thermal losses and signal degradation that often accompany high output power. The result is an amplifier that \u003cb\u003eruns cooler, takes up less space, and delivers a sonic signature that is transparent, dynamic, and effortlessly detailed.\u003c\/b\u003e\u003c\/p\u003e\u003cp\u003eCHORUS is designed with high-performance signal modulators and driver stages, carefully tuned for musicality, transparency, and resolution, \u003cb\u003ebalancing technical precision with long-term listening engagement.\u003c\/b\u003e\u003c\/p\u003e\u003ch2\u003eDerived from Harmony GaNM.\u003c\/h2\u003e\u003cp\u003eCHORUS is a \u003cb\u003etrickle-down design from the LAiV Harmony GaNM,\u003c\/b\u003e bringing the same core GaN amplification technology to the Crescendo series at a much more accessible price point.\u003c\/p\u003e\u003cp\u003eCHORUS utilizes a stamped aluminum chassis and a 160W power supply compared to the 250W unit in the GaNM. Nevertheless, CHORUS continues to excel in transparency and resolution due to its wide frequency response and the inherent advantages of GaN technology. \u003cb\u003eFor listeners seeking GaN amplification's musicality and speed without the premium Harmony series, CHORUS delivers exactly that.\u003c\/b\u003e\u003c\/p\u003e\u003ch2\u003eTwo Modes. One Amplifier.\u003c\/h2\u003e\u003cp\u003eThe Crescendo CHORUS operates in two distinct modes, each \u003cb\u003eoptimized for different system configurations and listening priorities.\u003c\/b\u003e Whether you need a versatile stereo power amplifier or a dedicated monoblock with a true balanced output, CHORUS adapts to your listening setup.\u003c\/p\u003e\u003ch2\u003eStereo Mode.\u003c\/h2\u003e\u003cp\u003eIn stereo mode, CHORUS functions as a single-ended amplifier with two independent channels, \u003cb\u003edelivering 50W per channel into 8Ω or 80W per channel into 4Ω.\u003c\/b\u003e Both XLR (balanced) and RCA (single-ended) inputs are supported, though the internal amplification remains single-ended regardless of input type. The balanced input offers superior THD and SNR performance. This is a plug-and-play configuration for most two-channel systems, offering broad compatibility \u003cb\u003ewith virtually any preamplifier or DAC.\u003c\/b\u003e\u003c\/p\u003e\u003ch2\u003eBridge Mono Mode.\u003c\/h2\u003e\u003cp\u003eSwitching to bridge mono mode transforms CHORUS into a fully differential, true balanced amplifier. A single input is received and internally converted to a balanced signal, driving both amplifier sections in a bridged configuration for 120W of true balanced power into 8Ω and 4Ω, stable down to 2Ω. \u003cb\u003ePeak instantaneous power reaches up to 165W.\u003c\/b\u003e Even when using an RCA input, the signal is internally converted to a balanced signal path to fully leverage the fully differential amplification architecture. Overall performance in mono mode is superior to stereo, \u003cb\u003ewith improved noise rejection and dynamic range.\u003c\/b\u003e\u003c\/p\u003e\u003ch2\u003eRecommended: Dual Mono Configuration\u003c\/h2\u003e\u003cp\u003e\u003cb\u003eFor the ultimate performance, pair two Crescendo CHORUS units,\u003c\/b\u003e with each unit operating in bridge mono mode. Each unit takes one channel, converts it to a balanced signal, and delivers 120W of true balanced output. With complete electrical separation between left and right channels, separate power supplies, and separate amplification stages, \u003cb\u003ecrosstalk is completely eliminated.\u003c\/b\u003e The result is a wider, more precise soundstage with better imaging, a configuration that elevates GaN amplifier performance to a reference level.\u003c\/p\u003e\u003ch2\u003eBalanced and Single-Ended Inputs.\u003c\/h2\u003e\u003cp\u003eCHORUS supports both balanced (XLR) and single-ended (RCA) inputs. \u003cb\u003eThe balanced input is recommended for superior THD and SNR performance,\u003c\/b\u003e as well as for longer cable runs and in environments where noise rejection is critical.
