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

There are so many new speakers out there.Just find something you like. Polk if you don't have alot of money to spend.You can buy used ,close outs,and save alot...good luck,my man.

If you are anywhere near North Carolina, I would highly recommend dropping over to audition the Fyne F704, great speakers that would be perfect for your room and are both gorgeous to look at and listen to. Rarely come up for sale. 

Monitor Audio makes a good line up of speakers at a good range of price points.

If you are near Los Angeles, Cal, I'd recommend to audition the Wavetouch Antero V2 speaker. Alex/wavetouch

If you have a $20k budget for just speakers, I would be looking used. There is a huge selection well under that price point that would be amazing. I’d be considering Sonus Faber floor standers. They just sound and look beautiful (if looks are important). Else there are KEF blades, Lower end Mágicos. If you want a panel, I would suggest Martin Logan electrostatic speakers.  I own and love a pair of Montis. But you probably could get even newer models for under 20k easy. 
 

you have many options. Best if there was a dealer near you that would loan you some to demo in your own space.
