Anyone know what else is in an Audience aR1p?

I've been thinking of building a high current version of a Felix for my amp. I've tried the aR1p. It sounds very nice, but I sometimes get the feeling on very powerful transients that there's a bit of compression or maybe softness compared to running the amp straight into the wall (Maestro outlet which I like very much, BTW).

So I popped the cover of my Audience to see what was in it. At the input side there are two .015 uF Auricaps, one going from the H to G, the other from N to G. Then the choke, then 4 devices in the expected H-N arrangement - a 1.9 uF cap, a .015 uF cap, and then two devices which are jacketed. Based on the the way they are wired I'm assuming they are two more caps of unknown value. My question is whether anyone knows what they are?

I'm not asking to uncover the secrets of the Audience design, really, but more so to understand why they went this route and how its results might be different from the Felix design. Is it possible one design might be better than the other for higher current devices like a power amp?

tonyptony, sorry to (slightly?) diverge, but can you tell what value the choke is?

Thanks,
Jim

No, I'm afriad not Jim. It too is jacketed. I have to assume (hope) they used a choke rated to support a theoretical 15 A load since the aR1p is rated for 15 Amps. If that's true then it can't be more than about 4 mH or so.

Yep, I agree.  Thank you, sir.
