I’m also worried about how much of the harmonics in the music is LOST by the amp?

Can also be lost in the type of amp used, when phase shift happens to the 2nd 3rd 4th harmonic structure of the fundamental, mids and highs notes above in this case Class-D >1khz.
As can be seen (red trace) there is 75 degrees!!!!!!! of phase shift at 10khz cause by the switching noise "output filter" in this Class-D amp, and still 40degrees!!!! at 1.5khz. https://ibb.co/cCL1M8k

This is an older design that does not reflect modern class D amps. A good class D amp will have less than 1 degree of phase shift at 20KHz.

I live in hot as hell Sunny South Florida. My house is open beam ceiling (no attic). Upstairs without air conditioning on is 95* +!

I finally got around to getting the roof top Siliconed to knock down the heat and UVs= lower electric bill. What I didn’t expect was the impact it would make, quieting my listening/TV room. For the first time in 25 years, no traffic noise from nearby I-95 and I-595!!! And when I turned on the TV the sound was relaxed, not echoing in the room.


Listened to a variety of music that I am very familiar with, including; Bonnie Raitt, Chris Isaak Heart Shaped World, Jennifer Nettles Playing with Fire, which is one of the worst recordings Ive experienced, but I love the songs. To be fair, some songs are pretty well recorded, but the title song Playing with Fire is a hot mess, but I hear so much more of the music, chorus, etc, then ever before.


Well, I finally hear a lot more of the nuances that was/were recorded. The entire sound stage has opened up in a very big way, notes are much more complete (think micro details)


Glad I did this before my Voyager amp arrives mid week. I need to get a handle on how the silicone changes the sound before I put the V in the system
