Best SET speaker combo under 5k new or used

Polk lsim707 with SAE 502 amp ,Nad C588 with Ortofon Blue Cart.,,Schitt Mani pre phono ,Zixang Sgeng tube pre Amp ,Onkyo C7030.But I change my equipment often.

I'm thinking you could get Coincident Frankensteins paired with Coincident Triumph Extreme II  for just a bit over 5K.  That is a pair that works really well together.  I rebuilt the crossovers in my speakers for about $500 and added a sub.  Really nice, especially with upper tier 300B tubes.   

Not sure why this post didn't generate more response.  Seems like a reasonable request for information, although a 5K limit on an SET amp/speaker is a little low even used.  

ok, let’s raise the bar to 10k

May I ask what SET is? 

SET= Single ended triode.  As a typical example, an amplifier using a triode tube, such as a 300B, with one tube per channel.  

Dennis Had sells his single ended (masterpieces of point to point wired brilliant sounding things) hand made amps for around 1700 bucks more or less, and a pair of Klipsch Heresy IVs (I use a Had amp with Heresy IIIs, and it's the best rig I've owned in decades) are around 3 grand or so. 

Decware and Omega have nice synergy according to many (including me). I use Decware's SE84UFO with Omega Super 3i's and DeepHemp 8 Subwoofer. Lot's of SET magic for under $3000.

The new Tekton 2-10 Perfect SET for speakers with one of the amps you already have in mind.
