Help me emulate the best speakers I've heard

If you think the sound of the Shahinian Compass is the best you've ever heard, I suggest you may not think as highly of anything not made by Shahinian Acoustics.
The designer, Richard Shahinian, designs very much and closely to his own taste. All his speakers above a certain price point (about $6000) are polydirectional multi-driver units with 8" bass drivers in a modified transmission line enclosure terminated in 10" passive radiatiors. The Compass, while having only 2 drivers and no passive, is an attempt to duplicate some of the omni-directional qualities of his more expensive models. The obvious sound preferences, besides the spaciousness of poly directionality, include powerful dynamics, explosive bass and a rich midrange.
I have heard (and owned) only the Obelisks (c.$8k) and the Hawks (c.$15k). I have not, unfortunately, heard the Compasses but I am assuming they will share the family resemblances I have suggested and therefore, like the models I know and love, will be distinctive, not like any other speaker, really.
I have owned Ohm Walsh speakers, also omnidirectional but "single'' driver. They cast a soundstage similar to the Shahinians but they lacked the succulent midrange, the overall dynamic impact and the powerful bass.

But you can't, unfortunately, go to a showroom to audition. They do not market to the United States. The reasons for this are a bit obscure but definitely relate to the (not untypical among highly talented people) crankiness of the elder Shahinian.

But here's the good news. A new pair of Compasses costs only $4800 factory direct. That seems to be right on your budgetary cusp. And their factory is right here in New York. There is a waiting list since they sell heavily to the rest of the world.

I have no connection to this company. What I do have is a deep respect for their business practices, their straightforward honesty, and their glorious products.

By the way, the company is now run by Richard's son, Vasken.

The Vienna Philharmonic playing Bruckner in Carnegie Hall produces a full, rich, plump, microscopically textured wall of highly fattening tone which can fairly be described, overall, as 'succulent.'
This sort of symphonic plushness has been well captured on, for example, many Decca/London LPs. I heard the CSO under Solti in Davies Hall and was almost overwhelmed by the sheer physical gorgeousness of the sound. On a steady diet of that kind of experience, I am sure I would put on at least 25 pounds.
And, though the bass is a serious force here, and the harmonic richness certainly depends a lot on the smoothness of the 'treble', I believe live midrange is often and somewhat reproduceably caloric enough to be placed on the menu with Savoy Truffle and rock solid images.

As for comparing the Walsh 200 with the Obelisk and the Hawk, I drove both with a Sunfire Signature 600 which produces lots of nice current on demand. The Ohm is a fine loudspeaker but I was comparing it to two specific Shahinian models (and, of course, ultimately to live music) and--compared to them-- the midrange was A LITTLE BIT leaner, less 'succulent,' and the bass, while beautiful, detailed, deep and very musical, had not the dynamic power of the other speakers NOR OF THE LIVE MUSIC I MOST LOVE.
The original question had to do with the questioner's feeling that the
Shahinian Compasses were the best speakers he had ever heard. Again I say, if that's how you feel, you probably will not like other manufacturers' speakers as much. In other words, 'emulating' the Shahinian sound is difficult to impossible.

There's a pair of Shahinian Arcs listed right now on Ebay for a buy-it-now price of $1000.
That's a steal even if you have to invest another $1000 into factory restoration. The Arc is the next model up the line from the Compass and is almost certainly similar in sound to the it only moreso.
