Best speakers for max. $3000?

From what I’ve read about them nothing new at $3k is going to be much of an upgrade.

Here’s an apparently level headed review from Doug Schneider:

So you’re best looking at used, and even then there’s nothing obvious to report. At this point real full bandwidth upgrades start getting costly. Harbeth M40s, big Tannoys or DeVore models, Wilson’s, and yes the Thiel 2.4s may also be an upgrade if this review is anything to go by.

It looks like you’ve done your homework. Hopefully you can pick them at a good price after arranging for a home demo first.

You should seriously consider Spatial Audio M3 Turbo S. They perform way above their price point.
