I would rather put the extra filters inside the Pro so you only have one controlled point of filtering on the circuit, too many added PE's on the same circuit will close down the top end real quick with this design...it's best to tune all the filtering through the dual resonator filter. The V Pro is set up similar to what you described, you get the same benefits as multiple PE models, dual PE II's, etc. Use the extra filter to tune other circuits in the house....every tuned circuit on the same phase is audible through the stereo, so you don't loose anything from your investment, and you don't experience any top end closed down doing it this way. As I mentioned before, the V basic design allows me numerous areas that can be tweaked in order to turbo charge the PLC's performance. Best to sit down and talk to me right before you place the order so we design a filter that meets all your needs. The Pro that I built for myself has two added filters and it sounds fantastic and really does a nice job on video reproduction. It also appears to work really well with common Audiophile tweaks like Bybee's, Quantum Symphony Pro's, balanced a/c, etc. The Pro combines parallel filtering with magnetic and resonate....the some of the parts really make a killer package.
Jen spoke to me last week or whatever about Ti-Shield inside the wall box, how did that work out for you? Please excuse...I'm a little punchy this evening...haven't slept in the last two days and wired to the roof.
