For me, the last day of a show like FSI is for checking up on rooms that I somehow missed (and that I heard people talking about), and re-visiting rooms that were particular favorites.
Rooms that I had missed, but was able to catch up on, included the Tenor Audio/Avalon/Audio Aero room, the Fidelity Audio/Nagra/Verity room (with Rene Laflamme playing the superb high-resolution version of his official FSI show recording), and the Ayre/Verity room: all offering great sound—and all in a price range that's expensive by almost any standard.
At a price substantially lower than these stellar offerings—although not quite entry-level—was the room featuring ProAc D Two speakers driven by the Leben CS600 integrated amplifier. This just seemed to me like a well-balanced system in every way: sound quality, with equipment that's not over-the-top in price but offers solid value, and has an elegant appearance. I was quite taken with the retro look of the Leben CS600 ($5000, EL34 tube-based, hand-built in Japan, with point-to-point wiring) which just oozes quality in a way that recalls the classic Marantz components.
