The original SRS platform was custom ordered for the ARS amp, but was not correctly balanced and so I returned it to SRS and they replaced it with a "universal" platform that was tuned to the ARS specs. It comes with a one time upgrade if I ever change amps.
To Ryriken, I use a putty similar to blue tak to attach the speakers to the Osiris stands.
System edited: Finally updated pictures to reflect recent upgrades which include the TAOC AS-3 rack, Ars Sonum Filarmonia integrated amp and Ekornes "Orion" chair.
