Thanks for your comments.

For those that might be interested in how it works, the SP (speech circuit) is actually a combination of a gentile compressor paired with a three dB boost in the critical voice frequencies.

To calibrate this feature we actually listened to two shows produced by Aaron Sorkin: The West Wing and The Newsroom. Both shows are characterized by quick dialog and in the case of the West Wing-overlapping dialog, which can create challenges in delivering crystal clear intelligibility. The speech circuit dramatically improves this issue. In addition, for late night listening, the circuit is invaluable.
