And well: there is a newcomer: the M23 power amplifier. @4ohms they make about 500watts similar to using two of the Benchmark AHB2. What makes the Benchmark AHB2 so special is its high efficiency and very low distortion and noise levels. This combination yields arc welder power stats. Especially in the case of the Master Series. You might look at Benchmark Media Systems’ AHB2 power amplifier ($2995 USD) and assume that it has been in production since 1991. And tube preamps have higher output impedance than solid state preamps. Specifications: DAC3 HGC. Both products are extremely competitive: good pricing, good performance and – our opinion – a sleek appearance. py an yw sz ht fi cu px zj it
