MUSE houses the transformer in a separate chassis to keep magnetic fields away from the audio circuits. The result is a quiet noise floor and wide dynamic headroom that preserves low-level detail and big musical swings.\u003c\/p\u003e\n\u003ch5\u003eGain Stages and RIAA\u003c\/h5\u003e\n\u003cp\u003eThe first stage uses a Class A topology derived from professional microphone preamps for optimal low-level signal handling. RIAA equalization is executed with a passive network chosen for stability and accuracy. Subsequent Class A gain stages bring the signal up to line level without adding glare or haze, so transients remain sharp and tone remains natural.\u003c\/p\u003e\n\u003ch5\u003eComponent Matching and Channel Precision\u003c\/h5\u003e\n\u003cp\u003eCapacitors are measured and paired within tight tolerance, then installed as matched sets per channel. This attention to part selection keeps left and right channels aligned in level and phase, which you hear as a stable center image and coherent soundstage.\u003c\/p\u003e\n\u003ch5\u003eMUSE Power Supply Details\u003c\/h5\u003e\n\u003cp\u003eMUSE employs a low-noise toroidal transformer, a capacitance multiplier stage, and very high quality voltage regulators to deliver two highly filtered and tightly regulated DC rails. Keeping the transformer outboard reduces radiated noise inside the audio chassis. The included UK-made DC umbilical uses silver-plated OFC conductors with FEP insulation, cotton wrap for mechanical damping, individual AL-foil Mylar separators, a high-density tinned copper shield, and ChorAlloy-plated multi-pin XLR connectors for stable, low-impedance terminations.\u003c\/p\u003e\n\u003ch5\u003eMechanical and RF Control\u003c\/h5\u003e\n\u003cp\u003eBoth Apollo and MUSE are machined from solid aluminium billets with thick back plates that fit together as a continuous Faraday cage. The mass and rigidity of the housings reduce mechanical feedback and keep RF out of the gain path, which lowers perceived noise and preserves microdetail.\u003c\/p\u003e\n\u003ch5\u003eIndependent Testing\u003c\/h5\u003e\n\u003cp\u003eThird-party measurements confirm extremely low distortion, excellent SINAD, and RIAA accuracy within ±0.1 dB from 20 Hz to 20 kHz.
