Help with high end bookshelf speakers

If you want to try an excellent sounding bookshelf speaker that can be had used for under $500 a pair, I would recommend the KEF Reference Series 101. It's very well made and similar in design to an early Rogers LS3/5A. It even uses the same drivers but with a different crossover. If you don’t like them you could probably sell them for what you paid.

You Mentioned reflections. I like the idea of the Revel M126 with matching stands. They are really good with reflection due to the tweeter 5th gen wave guide, they have some very nice finishes, and they sound good with the Hegel series. 
Another option is the KEF R3 or R3 meta with a Nordost Heimdall speaker cable. It good for reflection, great for off axis, and it comes in nice finishes. 
last would be the Dali Minuet SE. it can be mounted on the wall, put on a shelf, or on a stand because it was designed to be within 8” off the wall do to the 45 degree angle port design. It only comes in burned walnut. It basically a Dali Micro KORE. I would use a speaker cable without silver. I would even try the $40 Micca speaker cables on Amazon. Yes I own/ use them on my second system. 
I know these are common brands but I have actually had experience with these combos. I hope his helped out today. 

I'm curious why I didn't get the usual suspects when I asked about a high-end bookshelf speaker i.e. Sonus Faber, Dynaudio & Revel. Makes me wonder...

Because for some reason, and despite being asked repeatedly by several others, you’re providing no info on budget, what speakers you’re using now, what specific improvements/sound characteristics you’re looking for, or if your looking for new or used.  Stop wondering and just share this basic and critical info and you’ll get much better and more specific/targeted recommendations here.  Sheesh.  Help us help you.

In the past I have enjoyed great sound from BW 805 d4 in a bookshelf set up. 

Full disclosure:  I also have a pair of Brand New - with warranty- of white BW 808d4 available here for $6500. This is below the price for an open box pair.
