$15,000 Floor-Standing Speaker Selection and Advice

I just purchased a new pair of Legacy Focus SE speakers. I've heard them many times over the years and again at the AXPONA a couple weeks back. I'm coming from Magnepan speakers! Hard to go wrong with good quality full range speakers. 

Sonus Faber Amati Tradtion. Yes.

Klipsh Horns used with a pair of subs.

Revel PerformaBe F328Be new/used

Used Big Tannoys 

Perlisten speakers are a great choice from that list.  Not sure what else is available in Australia.  Suggest the Arendal 1528 towers if available.  They are big, have multiple drivers and will fill a large room with plenty of sound to meet your list of needs.  They also make great subs if needed. 

Perlisten Audio S7T, Revel 328be and Sonus Faber would be the three that I would pick myself personally. You really need to audition these in person and see which ones work best for you and the music you listen to. They all have different characteristics and honestly you can't go wrong with any of them, even the other ones on your list as well. The end of the day doesn't matter what anyone else says,. It's what you really like. 

Narrow it down to your final two and see if you can get it in home audition with them. If not, go back for another listening session. Make sure you're playing all the music you would listen to at home and don't forget the bass. These speakers well. They are great. They are not true replication of Base. All of those brands have excellent subwoofers they can offer you.

++ Legacy Focus.

You might consider the Fyne F-703s.  I have the F-702s and am very pleased with their music reproduction.  The F-703s are, here in the USA, right at your price point.  Amplification and speaker cables will have an impact on the tonal qualities, sound stage, and dynamics.  I am driving the F-702s with 200 wpc solid state monobloc and am very pleased with their music reproduction sound reproduction, although the F-702s have only 8”/200mm bass speakers while the F-703s have 10”/250mm bass speakers, so I added two Rythmik 12” subwoofers at a reasonable cost.  The Fynes provide a superb sound stage, three-dimensional dispersion, and excellent instrument and voice tonal qualities.  If they are available in your area they are definitely worth a listen.

So many excellent options at your price point.  I'd absolutely buy used from a highly regarded reseller here for around 50% off new pricing.

I am a Rockport fan and there is a pair of Atria 2's for sale close to your budget - no relation to the seller.

In that price range you should look at the KEF Reference 3’s or used Reference 5’s.  

Another vote for Legacy Focus SE.

At $15k, I would consider used Sonus Faber Amati Tradition…….or get two REL subs and pair with Sonus Faber Olympica III or Olympica Nova III. 
I have SF Olympica III with dual REL 212 SE subs and is extremely comparable to Amati G5 without subs. I honestly can’t tell the difference, except I can turn my subs up higher if I really want to. 

Another vote for Rockport! World class speakers that are universally praised and built right here in America. Good luck in your search! 

Many great speakers mentioned here. It depends on your personal tastes, music, ancillary equipment etc. If you prioritize live, dynamic sound  without being hard or harsh at any volume level, check out Volti Audio. Very few speakers in this price range can equal them in this regard.

+1 I owned Olympica 3 for many years. MacIntosh is often sited as a good match, as is Audio Research if you want a more detailed an balanced sound.
