Well, I spent a couple hours investigating this further tonight. In a nutshell... RANDOM result.
First off, I had pulled the "transmitter" off the top of my permanent doorbell chime, trying to determine how it works, what frequency, etc. When I put it back tonight, I couldn't (initially) get it to to trigger at all with my "In Trutina" test track. After replacing the batteries, and adjusting it's exact positioning a bit, finally got it working. I tried five repetitions of the test, using coax out to my Benchmark DAC, with "mute" off, then on. This time, I got random results, with the chime ringing once (sometimes even twice), or occasionally not at all, even before changing the "mute" setting. Having the analog RCA cables attached or not did not matter. However, I found that if I adjusted the Benchmark volume attenuator ONE click up or down, I could "turn on" or "turn off" the effect pretty consistently, regardless of whether the mute was invoked. When I posted my initial "chime" observation a couple days ago, I had only done two repetitions of the test, and quit, since I had 100% consistency on my findings. In retrospect, I should have done a few more repetitions to be sure. I think what happened is the Benchmark Volume setting was "straddling" the range that can trigger zero, one, or two, rings, possibly depending upon where I was standing during the test. I still "think" the analog muting DOES have audible improvement (in my setup), but can no longer offer my "chime extender" as objective proof. Hopefully somebody with an oscilloscope, or some other more "objective" measure, can definitively prove whether or not the mute tweak is real, or just a ding-dong theory. :) -- sleepysurf squeezebox2 (with elpac linear psu) to benchmark dac1, direct to sunfire cinema grand 200 ~five (vertically bi-amped) driving ml aerius i's, blue jeans cables.
