I25 – modular integrated amplifier

•⁠  ⁠Overview – The Edge G3 Integrated Amplifier, released in the early 2000s, is a solid state Class AB integrated amplifier featuring high-current output stages and refined preamplification for authoritative, full-range loudspeaker control.

•⁠  ⁠Power & Drive – Delivering substantial current capability, Edge G3 Integrated Amplifier provides confident bass authority and stable performance into demanding loads, maintaining composure and dynamic headroom during complex musical passages.

•⁠  ⁠Build & Circuitry – Built with robust chassis construction and dual-mono inspired layout, the design emphasizes short signal paths and substantial power supply reserves to preserve transparency and channel separation.

•⁠  ⁠Specifications – Solid state Class AB topology, approximately 100–150 watts per channel into 8 ohms, high-current output stage, multiple line-level inputs, frequency response extending beyond 20 Hz–20 kHz with low distortion.

•⁠  ⁠Dimensions – Approximate dimensions are 430 mm wide × 150 mm high × 400 mm deep, providing substantial internal transformer space while fitting standard hi-fi racks.

•⁠  ⁠Weight – Weighing approximately 18–22 kg, the amplifier’s mass reflects its large power transformer and heat-sinking required for sustained high-current operation.

• Overview – The Musical Fidelity A120 10th Anniversary Integrated Amplifier is a British-engineered pure Class A design from the mid-1990s, renowned for warm, refined musicality, detailed midrange and engaging analog-like character.

• Sound Profile – This A120 edition delivers exceptionally natural tonal balance, rich harmonic texture and smooth dynamics that reward careful system matching, especially with full-range floorstanders and bookshelf speakers.

• Feature Set – It includes a versatile analog input suite with dedicated MM/MC phono stage, multiple line inputs and robust discrete amplification topology tailored for high-fidelity two-channel listening without digital artifacts.

• Specifications – Classic pure Class A architecture produces ~40 W per channel, high current capability, broad frequency response, low noise floor with strong stereo imaging, and internal heat management that supports consistent performance.

• Dimensions – Amplifier chassis measures approximately 430–450 mm wide × ~100–130 mm high × ~300–350 mm deep, designed to fit standard hi-fi shelving with ample ventilation for Class A operation. 

• Weight – Robust construction features a heavy-duty power supply and large heatsinks; unit weight sits around 15–18 kg, emphasizing solid build quality and vibration resistance.
