Good Speaker within a budget of USD10,000

Assuming you are looking at floorstanding speakers, there are a couple pairs of used Raidho’s out here.  They would be at the top of my list though you do need to have the right room for them.  All Raidho’s need 3’ of space behind them and 9’ of space between the speakers.   The X3s that are listed need a good 4’ from side walls because of a side firing bass driver.  The Cs that I saw listed can be close to the wall without issue.  

There are are tons of other speakers that I have seen listed in this thread that are great.  I would be biased toward used Wilson’s or Magico Ss if you can find them on your budget.  

If you were looking at stand mounted speakers the list would be different.  

Listening to The Black keys ‘turn blue’ on a pair of meridian dsp 8000’s I got used for around $10k and I haven’t heard better for the same money.

The problem for me is after I spend $10k on speakers I got nothing left to match components. Many companies getting into active speakers and the ones ive heard sound better than the passive version.

Agree the Meridian DSPs are tough to beat when purchased 2nd hand.  The advantage is that you don't have to worry about matching pre-amp, DAC, and amps as these are all already built into the speakers.
