Description :
The Krell Studio, like the MD-20 has the black-grey-black-grey-black front panel, with vertical rows of red LEDs at the edges. the left row indicates sampling frequency and emphasis, locking when the DAC receives a signal. Krell wrote the software for the logic chips which control data recovery and clock synchronization. Each channel uses two 20-bit DACs operated in push-pull configuration. With 24-bit input through 20-bit DACs the detail resolution is improved substantially. The push-pull configuration eliminates zero-crossing distortion. The DACs' output is connected directly to the analogue output stages; there are no capacitors in the signal path and servo amplifiers ensure that no DC reaches the main outputs. The analogue section employs output amplifiers based on those used in Krell pre-amps: high bias, complementary Class A designs. When played with the MD-20, instant synergy was achieved. Both units perfectly complement each other well.
