The G55 provides clean, superb-quality amplification for surround-sound and other applications requiring a block of five channels. Each channel delivers 100W into 8Ω. Massive twin toroidal transformers and over-engineered power supply ensure that power is always available on demand for high levels and heavy transients. 25 pairs of selected, thermally and electrically matched output devices maximise inter-channel uniformity and the highest efficiency and performance. The result is a clear, open sound with detail as well as punch where it’s required – at any volume level from a string quartet at midnight to Metallica at high noon. Both balanced and unbalanced inputs are provided: unbalanced inputs are balanced before they enter the amplifier itself. Fully DC-coupled, the signal path contains no capacitors, while those in the power supplies are audiophile grade components. The amplifiers are of a unique low-feedback design for minimum transient and interface intermodulation distortion, offering superb clarity and transparency right across the audible range, with an output impedance that is close to zero and suitable for virtually any high-quality passive loudspeaker system.
