Classical recording methods vary widely, and one can find good examples of each as references of what can be done generally, how they sound in an overall sense and in comparison with each other. But using a fantastic sounding recording made with lots of microphones may not be an appropriate benchmark for comparison with the two microphone stereo recordings most around here are making, and most modern classical commercial recordings are made that way, for large ensembles at least.
For some excellent recordings made using simple two-microphone only techniques, including large ensemble classical stuff, you might check out some of Kavi Alexander's recordings on the Water Lily Acoustics label. I love the recordings of his I've heard such as his Grammy wining "A Meeting by the River" with Ry Cooder & V.M. Bhatt, and have been meaning to check out his well regarded two-microphone symphonic recordings as well. He's recording style is closer to the ways we do it than most classical recording engineers.
