How Science Got Sound Wrong

And I use the floor's wood grid as an assist for listening chair(s) positioning, as those chairs are moved 'situationally' also, turning around to be part of home theater, back around for music system, centered for 1, off center for two. I also have a vase on the window sill perfectly centered, which helps center my head when sitting this way or that, and gives the brain a center before/during listening.

This setup is how I found that very slight balance adjustments can make a big difference on certain tracks. Remote balance from listening position allows refinement, track to track. I wish my integrated amp had remote balance. I use my Chase Remote Line Controller now.

I found it interesting.

I find Analog LP's (lots of old analog record cutter produced ones) and Reel to Reel, (analog mic to analog tape) more INVOLVING than Digital.

I have simplified the difference as "Analog gets Overtones Right". 

I wish the preserved timing advantages of analog, and the resultant timing of overtones was discussed.

I agree about precise positioning of speakers.

Happily I have an old wood floor, like grid paper on the floor, which allows me to move them into a few 'situational' positions without a ruler, including matched toe-in. I squished a speck of paper into the grid for the 2 front speaker corners.

They are very heavy, on 3 wheels, (3 will always settle with no wobble, and their weight prevents any vibration, no spikes needed for these).

I also believe in time alignment of various frequencies, so I tilted my speakers base a bit back (also changes reflections off both floor and ceiling, and resultant back wall).
