I should start with speakers. This I know. I’d like to establish a new system.

I like the idea of traveling to audio shows. I’ll need to keep an eye out for where and when can work for me. And yes, I’ll need to take my time. I was getting a bit antsy once I restarted my journey. Reading reviews and discussions herein along with the vast array of products gets me a bit worked up. I can be too impulsive. After all, the hunt is fun.

Choosing a speaker first may be a good direction to take, however making that choice should and really must involve some serious auditioning. If it were me attempting to make my speaker choice FIRST, and assuming that I discovered a set of loudspeakers that really "rang my bell" (assuming that the audition involved some music and recordings that I enjoy and am familiar with), after the audition, I would make careful note as to the exact components used in the audition. Next, I would attempt to locate another knowledgeable brick and mortar dealer that has the same speakers but is recommending different system components to drive them.

This approach gives a person an opportunity to determine how those speakers perform with a different set of variants. If you come away from audition two, with a satisfactory conclusion, than there is better than a 50/50 chance that you will truly be satisfied with the purchase. Especially if you choose your components as a 
"post facto" approach, and of course, select components by reputation and hopefully, by audition.

Frankly I have found over the past 30 years or so of working with a wide range of audio reproduction components at all price levels, that most people I have run into tend to do their selection process in reverse to what you are planning. Honestly, I can't authoratively say either approach is the best road to take.

One thing I can inequitably say and recommend to you, is to "stay away from audio shows as a definitive way of making component selections".. Frankly, I haven't heard an audio demonstration since the late 50's at a major audio show, that really" rocked my boat" and has stuck in my mind all of these years. 

I noticed HARBETH as a recommendation. HARBETH is very high on my list of top speaker choices, but - - - I consider HARBETH a musician's speaker. Classical and Jazz sound incredibly realistic, (depending on room setup) They are not necessarily the most likeable choice for a person who has musical tastes in the direction of "ROCK", FUNK"; ABSTRACT MODERNISTIC SOUNDS, etc.. Especially to a person who prefers disproportionate, over driven bass reproduction.

There are a lot of fine speakers out there depending on taste. {Choose wisely grasshopper")

“HARBETH is very high on my list of top speaker choices, but - - - I consider HARBETH a musician's speaker. Classical and Jazz sound incredibly realistic.”

My music taste is all over the map. I do like classical, acoustic and human voice. I’ve mostly left the hard rock of my youth, however I did enjoy “Becoming Led-Zeppelin” at an iMax theater this weekend.

Huh, What?? Harbeth is not a musician’s speaker.

This is a musician’s speaker, made by the guys who made all the musical instruments.

Harbeth knows something these guys didn’t? or what?

@yyzsantabarbara  A local guy to me is selling an almost new Blade 1 Meta for $18k. His ad and 2 others for under $20k are on USAM.

That's great to know. I don't know how the OP feels, but in my view, $18k or so on speakers almost depletes his $20k limit. If I had speakers as good as the Blades, I'd probably want a bit more in reserve for a power amp and other aspects of the system to fully optimize those speakers. $18k leaves him $2k, which doesn't leave enough budget, IMHO.
