Schumann Resonator

@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. 

mahgister,

Take it a little lighter. Whatever you want to write, wait until tomorrow. Your post was a bit contradictory in some places.

"You are an unpaid sellers of new products my friend not someone able to build a system, someone who BUY ready made electronic components..."

What does this mean? Is he a seller or a buyer? Those two may be different. Is there some other meaning of that sentence? Could you rewrite it?

"I created for 500 bucks my own system, not with upgrades but with elementary scientific facts..."

"By the way i succeeded to reach a great S.Q. at NO COST....."

Is it no cost, or is it $500?

"I dont pretend to have the greatest system , read me right please, but my modest system work at his optimal quality working...."

That is great, but it has nothing to do with the rest of it. It only says that your system is as good as it can be. Which my transistor radio is, too. Except that my radio is not that great despite being as great as I can expect it to be. I am not saying your system is not great, you have a model up from my wonderful old speakers which means it must be the best out there of course, but that your statements make very little sense.

Why being so mad that people buy more expensive things from time to time? Why does that bother you?

Calm down a little bit. From this distance, it seems you are losing your composure.
