The Vandersteen 3A is a higher-end variation on the theme established by the company's first loudspeaker, the 2C. The latter is still available, though much updated into the current, highly popular 2Ce. A four-way design, the 3A has separate sub-enclosures for each drive unit; the whole affair is covered with a knit grille-cloth "sock" with wood trim end pieces. A rear-mounted metal brace allows the user to vary the tiltback—an important consideration for best performance with this loudspeaker.
Denon's AVR-4308CI impressed, with very good power results, and virtually perfect noise and linearity performance. Power with stereo channels driven handily bettered Denon's 140 watts spec, and performance with 5 channels driven was only a scant half-dB shy of that mark, at 126 watts.

Pioneer's latest A/V receiver produced uniformly excellent bench results: linearity and S/N were close to perfect on both PCM and Dolby Digital signals, while distortion and frequency response were nearly as good (the latter, in particular, on 96/24 PCM).
As seems usual for Onkyo, the TX-SR605 showed just how technically accomplished mass-produced electronics can be today, with perfectly flat frequency response and perfect D/A linearity to -90 dB (and beyond). Both are as good results as I've measured, and while my memory isn't infallible, I believe this to be the first time these two particular aces have been drawn by the same unit.
