what is the best sounding speakers for under 5000.

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.

A third vote for AudioKinesis. Duke's speakers do Zeppelin just right--most don't IMO--and I'm a major Zeppelin head. Just the right amount of finesse for classic rock without masking anything. Bonham is trying to bash his way out of my room right now on Zep II, and I'm loving every minute of it.

Magnepan 3.7s and haggle a little bit?

I’ll second the Ohms. In the past 40 years, I’ve owned/reviewed the following speakers ranging from about $300-10,000/pr. Wharfedale W60, EPI 150, Braun L710, DCM Time Window, Spendor SP1/2, Mirage M3-si, Monitor Audio Studio 6, APL Serenade, JM Labs Daline 3.1, Micron Karat, Wisdom Audio 50, Clements 206di, Shamrock Eire, Equation 7, 9, Silverline S12, SR15, SR17, Panatella, Sonatina, Sonata, Galante Rhapsody, SAP Quartette, Klipschorn, Klipsch Belle, Heresy, KG4, Shahinian Obelisk, Omega Super 3, Harbeth C7II, Lamhorn, Altec Valencia, JM Reynaud Twin, Trente, Offrande, Magneplanar 1.2, GPA 604-8H, Ohm Micro Walsh, 100, Ohm 3000.

I’d rate the Ohms on top for overall sonics, ease of use and their ability to play music.
