The McIntosh MA5200 is an integrated amplifier with an onboard dual differential DAC and moving magnet phono stage. It also includes an excellent headphone amplifier. The amplifier is conservatively rated at 100 watts per channel in to 8 ohms. Laboratory test results indicate actual output at 135 watts per channel in to 8 ohms and 200 watts per channel in to 4 ohms. The amplifier's sound is beautifully balanced with an ease of presentation and musicality that McIntosh is famous for. Please read the outstanding reviews of this integrated amplifier and see my excellent Audiogone Feedback.
