what is the best sounding speakers for under 5000.

I was going through the same thought process as you recently. I just got a set of PSB Synchrony Ones. I still have my Stratus Golds. The Ones are similar but better overall, from bass to treble. They are just more open, smoother in the treble and go lower in the bass with great articulation. I was quite satisfied with the Golds, but the Ones truly are better.
Not a huge difference in overall balance, just cleaner from top to bottom. I listen to mostly classic rock and jazz. If you liked the Golds, you will really like the Ones.

I would take a good look at Vapor Audio's Cirrus speakers. They start at about $3600 and go up with upgrades and matching stands.
I have a pair of Vapor's sibling speaker called the Breeze on order. I will be picking them up in a few weeks. The Breeze was a more affordable option for me.
Also used Joseph Audio Pulsars, the new B&W monitors with subwoofer .
Salk floorstanders are nice too. Devore Nines used.

I would recommend a home audition of whichever Ohm Walsh model is appropriate to your room's cubic footage. First, I would speak with Ohm by phone to see if your amp would be a good match. I haven't heard your PSBs, but I have heard others, and I personally found them a bit too bright for my tastes. My Ohms are very smooth, warm, yet detailed. They offer a very un-box-like sound, with a huge soundstage, and deep, powerful bass. I listen to a wide range of music, including rock, and they do a wonderful job with everything, IMHO. Your budget will cover all but the top of the line model, IIRC.

Yep Audiokinesis. Amazing value for the money.
