Seeking horn array loudspeakers with a maximum price of $17,500.00 per pair.

There is a new update coming for Klipschorns or LaScalas.  Those would be serious contenders.  The Bryston is just wrong for the speaker direction you want.  I would sell that.  $3 to $5k will get you a nice tube amp or small Class A solid state.

If you want to keep the amp, Magnapan may be a good choice. 

Horn speakers: Volti, Fleetwood.  There are some nice looking European horn loaded speakers but don't have any info on them.

Get the speaker before thinking about selling the amp for something someone thinks is better. Why do people insist on just throwing people into holes for no reason

Hornsub here.  I have a Speakers System Veneered in 1/4" Walnut including Custom Electronic Crossover.  JBL 2440 drivers with 2445 diaphragm that cross over at 300 cycles out on multicell horns.  Lows go to 15" electro voice drivers. I am using all Audio Note tubes 7 watts per channel.  The speakers were built for me when I was 30 years old, and I am now 95 years old.  I listened and have had many different speakers and I always went back to these horns and kept them. The price is $4,000/pair.  I live in Hemet, California.  If you are interested, please contact me at 1-951-927-9964 or email me at oroehl84@gmail.com.

Could it possibly be that these people have experience with horns and different amps and can offer sound advice? No, of course not. That would make too much sense....
