Simon, from Australia, Has a purists system, perfect turntable, really nice amp, and lives in a terrific place.
Hey Bill
1. The Ah 700 horns are running and they are beautiful – very happy with the sound . Soundstage is wide and instruments place precisely. I have been switching back and forth between the Ah horns and some 550 hz tractrix on the same drivers – Your horns are clearer and the treble much more precise and sweeter. They are clearly more neutral. Midrange tone is beautiful
I am still running tractrix for the midbass – the horns are cut out but not yet assembled – too busy at work at the moment but will let you know as soon as they are done
The sound is noticeably less open as you get to the cellos as compared to the violins – the conical are definitely more clear and wide open.
I am very happy with the horns but just to let you know the mounting brackets did not fit once bolted to the driver – the bolt circle is inside the flange on the horn so took a couple of hours with a file to get them to mate – just for future reference .
Thanks Simon

Hi Simon,
Thank you very much for your kind words. I'm glad to hear the sound to your liking.
Many years of work and testing have gone into the AH700.... your comments are echoed by others who have AH! horns.
I would be glad to send you a new stand. Filing aluminum is not the most fun.
I now have a precise jigging system and threading machine.
When you get your mid horns going, let me know.
Best,
Bill

Hi Bill
My Stuff does not get into boxes very quickly ( thankfully have girlfriend who appreciates the sound rather than the looks ) so most of it is not photo worthy.
The amps are DIY single stage rs241 – parafeed and the photo shows a separate power supply
I use K+K audio phono stage and the Semi DIY table with a Teres signature motor pod and an advanced analog air bearing tonearm with a zyx cartridge
PS, not sure if i said it but you are very welcome to publish any comments
