My client's loss is potentially your gain. 
The question that usually accompanies a purchase on Audiogon is, "why are you selling"? Of course, the implication IMO is you found something better. Such is NOT the case in this instance. My client's long-suffering wife is demanding to get her magnificent great room back. The speakers have to go. Take a good look at the room and you will understand why.

At $150,500 these $500,000 retail statement loudspeakers are priced to sell, not to begin a downward iterative negotiation.  If owning the best means buying fully depreciated -- look no further. If you demand a lower price, please look elsewhere if you value your time. 

Excerpted from Hi-Fi + Alan Sircon and Roy Gregory
"... This might sound strange, but one of the biggest challenges facing any speaker system built on this scale is the ability to sound small when the music demands it. It was a test the Coltrane Supreme 2 passed with effortless, almost contemptuous ease.

What we have here is a speaker that can do big and small, loud and quiet, can transition between those extremes and do it without strain or even apparent effort. Dynamic range is genuinely uninhibited, response quick enough to pass unnoticed, and distortion – the audible addition of color, subtraction, or rearranging of information – is vanishingly low. In common with other diamond drivers, the units used here are devoid of an audible breakup, harshness, or edge. What is perhaps more impressive is that used across relatively narrow bandwidths, these drivers also manage to match the energy levels of other high-frequency technologies. Marten has succeeded in producing a speaker that is astonishingly natural and almost perfectly balanced across its considerable bandwidth.

The Coltrane Supreme 2 also projects the most natural stereo stage we’ve heard to date. Not in the laser-etched, carved from solid, reach out and touch imagery overt manner of many more initially impressive designs – but definitely the most natural and naturally convincing.

The real beauty of the big Martens is that they are one of the least overtly impressive or showy loudspeaker systems available today. Where so many big speakers scream, “Look at ME, listen to ME!” the Coltrane Supreme 2’s seem to spend all their time doing their level best to disappear. Their refined appearance is matched by their sound – they don’t project that solid, slab-like bass so beloved of audiophiles, so prevalent in demonstrations, and so rarely heard in reality..."

"... At almost 6’ high, weighing 507 lbs, and costing $480,000/pair, the Coltrane Supreme 2 from Swedish company Marten was one of the more extreme loudspeakers at the 2014 CES. But to my surprise, playing my own recording of the Jerome Harris Quartet playing Duke Ellington’s “The Mooche,” from the CD Rendezvous, it sounded delicately detailed, with a superbly stable rendering of the recording venue, Chad Kassem’s Blue Heaven Studio in Salina, KS. 

Despite having a multiplicity of drive-units—one 20mm diamond super-tweeter, one 51mm diamond tweeter, one ceramic-cone midrange unit, one 8” laminated aluminum-sandwich woofer, six 8” laminated aluminum-sandwich woofers, and six 11” passive radiators—all crossed-over with first-order filters, this enormous speaker, driven by Pass Labs Xs-300 two-chassis monoblocks, spoke with one voice, perhaps I was told because all the driver’s acoustic centers are in the same plane..."
