The RAL are working out quite well. I'm also experimenting with the Running Springs Duke power conditioner on my 220s. I'm running a Duke for each amp on its own dedicated 20 amp circuit (on opposite phases).
It's funny you mention the AirSine as I might be heading to a friend's house today to do a comparison on the RAL versus the AirSine. Granted, it will not be on my system with the VAC gear, but it might be constructive nonetheless.
I definitely prefer my 220s on the no feedback setting. When I start to add feedback, the music loses a lot of air and openess. It is like a veil has been placed on my entire system. It is still very musical, but in the context of listening with no negative feedback, the shortcomings are readily apparent. According to Kevin, the use of feedback is system dependent so let your ears be your guide.
I also have a Phi 2.0 Master Controller on the way! We'll see how it stacks up against the linestage section of the Meitner/EMM DCC2. The Phi amps have a lot of gain and I'm using the DCC2 at the very low end of its volume control (25-35 out of 99) so I'm not sure if that is having a negative impact in any way. Plus I'll be getting a killer phono stage which will leave me no excuse NOT to get a vinyl rig!
