Looking for speaker recommendations that I can purchase on Amazon.com

Here are some quotes from KEF LS50 reviews:

https://www.whathifi.com/kef/ls50/review
"Given a little space to breathe and mounted on a pair of solid stands these monitors sound terrific. The first thing that strikes us is the quality of the bass performance."
"the LS50’s innate transparency means that any flaws in the partnering kit will be apparent. But get it right and you have what is one of the best standmounters below £1000, and easily one of KEF’s most musical efforts in years."
"the LS50's high frequencies sounded very clean, with no grain or steeliness. This is a high-quality tweeter. The LS50's treble did sound a little soft at first, compared not only with the DeVore O/96 (reviewed by Art Dudley in this issue), but also with the mellow-balanced Sony SS-AR2 (reviewed by me in October). The ostinato hi-hat cymbal in "The Trader" sounded a little subdued, though cymbals in more recent recordings, such as my own Rendezvous (CD, Stereophile STPH013-2), were reproduced with a natural tonal quality and precise, stable stereo imaging."
"Listening to our two sopranos, Julie Adams and Carin Gilfry, and comparing what I was hearing through the KEFs with my memory of what I'd heard live at Bill Schnee Studio, I would go so far as to say that the LS50 is one of the finest speakers at reproducing female voices that I have heard"
"Next up was the identically priced but somewhat larger Bowers & Wilkins CM5 (reviewed by Robert J. Reina elsewhere in this issue). The CM5 was noticeably more sensitive than the LS50, and had a lighter, airier balance, but was also slightly laid-back in the treble"

"LS50 is one of the best small hi-fi speakers I've heard at any price."

"The LS50 is tuned for smaller rooms and is meant to take advantage of the room gain that can give mid- bass response a boost."
"The KEF LS50 is one of the most all-around-satisfying little speakers I’ve reviewed in some time."
"The mid- and upper-treble range is smooth; the sibilance region is controlled— crisp and clean, but with compliance."

Selected quotes from reviews of the Dynaudio Excite X34 2-Way Floorstanding Speakers.

What is "upper treble shading"? Is that the opposite of brightness? Could shading be something positive in my case?

http://www.theabsolutesound.com/articles/dynaudio-excite-x34/ "In tonal balance, the X34 is reasonably neutral with the exception of some upper treble shading, and a hint of mid/upper bass ripeness. Strings could be sweeter—they tend to be a little dry, and violin section layering is not quite fully explored."

"you should combine them with amplification that doesn't add anything from itself to the upper midrange, or maybe even is a bit shy in this area. These speakers aren't really bright sounding, but they are capable of delivering so much information that less expensive amplifiers are not able to deliver. ... I would suggest pairing them up with amps offering a bit warmer sound. Heed, Roksan, Advance Acoustic – you should look among these. Clones Audio should be a nice partner too. Or some tube amplifier."

"Their sound signature is somehow specific so you need more time than usually to discover what this sound is about. To achieve this kind of sound (that many will recognize as the right choice) Danish designers had to make many choices. One of them was a choice of tonality. X34 offer „fresh”, open sound – I've already mentioned that. They deliver a lot of information – we know that already also. To use these features to the maximum a decision was made not to roll off the upper midrange. I'm talking about the range between 2-4 kHz that is powerful and unambiguous."

https://www.whathifi.com/dynaudio/excite-x32/review "We love these Dynaudios. We're keen on the Excite range as a whole, but it's these X32s that shine brightest. So bright in fact, they were triumphant in our 2008 Awards. ... With the arrival of new competitors (namely the Spendor A5s), we are starting to see small chinks in their armour, though. One is that when pushed to very high volumes, they do lose a little clarity and composure. The other is that the treble could do with a bit more sparkle."

http://www.hifi-review.com/153256-dynaudio-excite-x34.html "Excite X34 speaker systems showed smooth, organized sound. The dynamics is emotional, without overkill. Bass is well performed and quite deep and powerful. Musical scene is clear and spacious. A neat upper case fills the scene with naturalness and lightness. Timbre resolution is on top. The smallest details are well seen. Localization of the sound sources is slightly blurred. The sound of cymbals impresses - you feel metal, but not the bounce. The speaker systems manage to transfer the character of composition, the composer's idea. Electro music sounds very good."

Vandersteens are way more sophisticated than a Box
I heard the brand mentioned above last night again in one room the Vandersteen 3A Sigs another easy choice
Vandersteen phase and time correct use propitiatory drivers in a stepped baffle-less muli enclosure to negate unwanted boxiness and reflections that add artificial brightness. All drivers are in sinc with the pulse of the microphone preserving all the music's fundamentals and overtones intact.
 Unlike other speakers where some drivers in phase and others 180 out.
Kavi Alexander used these to master A meeting by the river. Rye Cooder Indian recording artist Hindustani Virtuoso Bhatt playing together won a recording achievement.
Vandersteen would want you to have the personal support that you deserve. The promise of making sure performance is delivered with all the details dealt with where mail order clerks just aren’t trained for this
Your call on what you deserve.

People who can’t be bothered to proof read their own professional work aren’t people who’s opinions I give much value to.

I’m pretty sure that should be, whose opinions I give much value to. I agree by the way. 😄
