Hi
@deigm
Class D is only appropriate for power amplifiers, so no the Upcoming Pre1 pre amp is based on some of the highest performing OP amps available. It is fully a fully differential (balanced) configuration.
The basic spec is:
3x balanced xlr inputs (fully compatible with RCA sources with adaptor cable)
1x RCA MM phono input
1x fixed level xlr balanced output (tape out)
1x fixed level rca output (tape out)
1x variable level xlr balanced output (volume controlled) 10v rms.
1x variable level rca output (volume controlled) 5v rms
2x 12v trigger outputs
Fully balanced topology
Remote controlled power, volume and input select.
Extraordinarily quiet and low distortion with Sinad >120dB.
