Even apart from MQA, the SE's are a big step up from the 8000.2's, especially with the latest software package (3.08), which brings everything into greater focus.

To come close to their ability to recreate performance spaces, you'd need two normal full-range speakers augmented by two subwoofers, plus amplifiers and cables to make it all work, plus a high-quality digital front end.

To match or exceed the 8000SE's, you'd need a system consisting of, say, a dCS Rossini or Vivaldi (with outboard clock), a SOTA amp like the D'Agostino Momentum Stereo amp, Wilson speakers (Sasha or Yvette) with matching Watchdog subs, and high-quality cabling throughout -- all of which will take up a lot of real estate and cost significantly more money.
