Thanks Warren. Just replaced the PS Ultimate Outlet (that was on the digital components) with an Audio Magic Stealth Digital. I think my system has arrived as well. Must be magic.
I've used the RCS with a 300B amp (using Sophia meshplates) and now with the SE45 (Emission Labs type 45). The RCS has been great with both though I prefer the SE45.
The Janis is driven by an Interphase 3 x-over/amp that is part of the W3 'system.' The crossover is at 100Hz with control for volume and phase. It's a 50w solid state amp. The Lowthers are run full bandwidth without going through the crossover.
