Looking at Marantz PM6006 vs Rega Brio power output we can conclude that Rega Brio is a bit more productive: here we have 40/8 and 58/8 W/Ohm respectively. Thanks to the built-in converter CS4398 (24 bit / 192 kHz), the amplifier can be used as an external DAC. To do this, on its rear panel there is a coaxial input and a pair of optical inputs.
When I opened it, a power supply unit with a powerful toroidal transformer and smoothing capacitors with a capacity of 10,000 uF was striking. “Trans” is located in close proximity to the front panel, being a natural barrier to high-frequency interference from the indication circuits. Another source of interference is a microcontroller controlled by IR signals from the remote. The output stages — low-impedance emitter repeaters assembled in a complementary manner on 150-watt Darlington transistors — operate in class A. Careful design of the circuit has led to a radical increase in stability and lower leakage currents.
