ryston’s 9B is a legendary line of multi-channel amplifiers. This new Cubed iteration lifts the performance of theaters and other multi-channel applications to new heights far beyond expectations set by inferior options. Now with each channel capable of 200 watts, more speakers than ever before can be driven with ease. Unlike most multi-channel amplifiers and receivers, the all new 9B Cubed features up to 5 self contained channels. Since each has a fully independent power supply, high output on one channel won’t be a drag on the others, so every note will be dynamic and clear.
