What is a good all around high quality speaker to purchase?

there are plenty of VG-EXC open baffles around. My choice for decades is Emerald Physics though no longer made. Typically available $1000+++

+1 for Fischer & Fischer 

The best all around speakers is the one that will match your system. There are so many out there, do a. Research and look at the recommendations here too.My recommendations try Borensen speakers, Cube speakers, Fyne speakers…

A perfect candidate would be the PS audio Aspen FR 20 ! If you want more of a traditional woody design there’s an endless list of Sonus Fabre Amati up grades available. Having said that with the FR 20s in place the Sonus would be history. Why ware Tennis shoes with a three piece suit, you’ve the perfect mates set up already IMO.

The contrarian move is Yamaha NS-5000 for $15K. 

It is a synergy of resources from the world's largest producer of musical instruments with a world famous motor sports business.

Add a zero to the price and the single material driver technology will not be matched. Cabinets are sustainable plywood from their wood instrument business  with a gloss finish from their grand piano business. 

Not the most exotic or luxurious. Not huge. They are a global model for living spaces that a woman will buy. My wife bought ours.
