Schumann Resonator

When a geophysicist, mathematician and co designer on some of my projects came to visit I had her take a listen to my just turned on system. I asked her to close her eyes and spread her arms to the left and right edges of the soundstage. She expressed 11 to 1..

After 45 mins of playing time and repeating the same tracks at the same exact volume for her to close her eyes again and spread her arms to the left and right extension of the soundstage... ...she expressed 9 to 3 so it is the width of the room at 20.5 feet. She couldn’t believe the difference saying there was no way warm up or breakin of materials could affect electron flow and make that sort of difference. She could not express a different reason as to why. Her exposure to audio is a Bose system and her daughter is a cellist. Tom

@cd318 - my point was that I was surprised that the improvement from changing arms from the Rega P5 arm (RB700) to the one from the P8 (RB880) ON the P5 table was much more significant than when I changed the table itself (of course keeping the RB880) from the P5 to the P8.

I expected the table upgrade to be more noticeable, especially since it cost more than the arm upgrade alone. I am still glad I upgraded the table because it has a few features I really like - the better wiring and connectors to the PSU and from the arm, and the dustcover design in addition to sounding better.

It would be interesting to compare the P8 to much more expensive tables if they were placed on a perfectly non-vibrating surface. Regas have low internal noise due to their low mass, but can be vibrated easily because of it. I guess that's why Rega sells wall shelves specifically for the P8/P10. If you really want to see the philosophy taken to extremes, check out the Rega Naiad. It looks like it weighs nothing. It is the design model the P8 and P10 are based on. i think it goes for $40K and is very limited in production, if at all. Probably by special order only.

@theaudiotweak - not surprising that warming up an amp for 45 minutes from dead cold would improve the sound. I think the argument that Doug is making is about burn or break in not being important, not warm up. I think that is universally agreed upon.

What will be the amount of warm up time for a super conductive material to reach it's stasis level?

It may depend on shear waves.

They will all have shear waves and at different velocities.
