I can't speak to your specific inquiry as to the Benchmark, but I currently own the 8260 and Perpetual Tech. setup with Modwright Sig. mods. While the 8260 gives a warm and muscial presentation, it is not close to the transparency, detail, etc. of the perpetual setup. I don't know how a stock Benchmark compares to a modded Perp. Tech. setup, but I would think there is more potential with the Benchmark (considering future mods).
