Equipped with an over-sized toroidal transformer and individual power supplies for each of its seven channels, the GX-7 combines considerable output with quiet, low-distortion operation. Because each channel has its own power supply, the GX-7 has significantly improved channel separation. Intended for...

The RX-7 is ideally suited to drive high-quality home theater and multi-channel music systems. Based on the design of the larger ZX-7, the RX-7 has a fully balanced topology. Due to its low distortion and quiet operation, it is capable of exceptional refinement of fine detail and resolution of low-level...

The ZX-7 features a true balanced topology. Each of its seven channels consists of two amplifier stages, one for each side — both positive and negative — of the wave form. The positive input signal is amplified by the positive amplifier and the negative input signal is amplified by the negative amplifier...
