Stereo set includes integrated amplifier Sharp Optonica 7100 H and tuner Sharp Optonica ST-7100 The amplifier is the top of the range and this really shows in both the sound and build quality. This is a very heavy unit due to the amount of high quality components packed inside. There are plenty of inputs which includes 2 amazing sounding phono stages for your turntable. There is all a preamp in & output should you want to attach this to a power amplifier. There are enough outputs to run up to 4 speakers, each output pumping out an impressive 60w RMS.
