Interestingly enough, Audioholics actually posted a press release on their website concerning this receiver (as well as Jamo's other electronics) in '04. The press release can be found here:

A few quotes from the release:
"The AVR-693 and AVR-793 feature
overspecified[?] toroidal transformers and high-grade capacitors (AVR-693: 40,000 µF,
AVR-793: 60,000 µF), for extra stability and large reserves of power." (Emphasis mine.)
"Users can also benefit from a six-step LF (low frequency) crossover as well as
individual bass management for front, surround and centre channels." (Emphasis mine.)
Correct me if I'm wrong, but individual bass management for each speaker (or at least, each set of speakers) is not very typical for receivers at this price point.
