Schumann Resonator


I got 2 of these from Amazon...careful that free returns are applicable.  I charged them up, turned them on and holy moly.....they do help with my system.   What I hear is clarity....space between instruments, a definite difference in upright and electric bass, wider soundstage...you know...all the good stuff. At first I thought it might be increased brightness, but no....it is still the same in that regard.  I still can't believe it, and will listen again tomorrow (saved the packaging for the return)...but today, I'm about to keep them.

@douglas_schroeder Nice article.You're going to raise some temperatures around here with MC at the head of the line of true believers regarding some audiophile tweaks like this Schumann Resonator thing (which I think is among the craziest I've heard of).

I do believe (and have most definitely heard) tremendous improvement is possible with vibration control of turntables, assuming they have existing issues with that as my Rega P8 did. I doubt putting the platform under an SME table would have the same impact. I probably had the most room for improvement - a 10 pound table sitting on a credenza on a suspended floor over a crawl space. Putting it on a wall shelf on top of a Townshend platform made it sound like a new table. It sounded almost as good sitting on the credenza and the platform, but that combo created foot falls that didn't exist before, so I had to put it on a wall shelf. Luckily, I was able to do that because I would have kept the platform without the wall shelf because it sounded so much better, and I would have lived with stepping lightly near the stereo.

I also believe as AJ van den Hul states in his 100 page audio white paper/encyclopedia on his web site that moving wires has a short term change in sound until returned to their steady state. That would imply that vibrations in cables, amps and the like would impact SQ, however, I don't believe it is audible under "normal" circumstances. I put Herbie's tenderfeet under my amp and phono stage because of the low cost and theoretical improvement, but haven't noticed any. I also had the high cost Townshend pods under the amp for a couple weeks and they made no difference. This is on top of the credenza and suspended floor!

Plinius recommends leaving their amps on, which I do, and really never experimented with turning them on just for listening sessions, and my phono stage has no on/off switch. Perhaps frequently turning the amp on and off puts some stress somewhere in the amp and may cause it to wear quicker? Their products will last longer and sound better from their experience, so who am I to question?

I was told that my speakers would sound better over time as the drivers broke in, but they sounded great from the get go, and I can't say if they improved over time as there is so much variation in SQ from album to album. Plus it's not like you turn a switch and voila, they sound better. It's probably very gradual like an asymptotic graph reaching a theoretical optimal level.

Like you, I am not interested in subtle or very subtle improvements, and I have been surprised by how little my turntable improved in sound in an upgrade from the Rega P5 to the P8 while using the same arm from the P8. If I can't hear am easily noticeable change when hooking up the new equipment or change, it's not worth it to me.

I think if people want to hear a difference, they can convince their brain that they do, but if they wanted to really be honest with themselves, they would do blind tests. I asked posters on this discussion to do that, and so far only one has done it and he said it made no difference to the sound, and maybe widened the soundstage very slightly.
Oh no now I no longer know what to do for sure!

@sokogear,

"Like you, I am not interested in subtle or very subtle improvements, and I have been surprised by how little my turntable improved in sound in an upgrade from the Rega P5 to the P8 while using the same arm from the P8.

Agreed in that it’s the easy to hear changes that are most satisfying.

It’s also good to hear that the P8 is clearly superior to the P5 as they are radically different designs.

I’m sure that many Rega owners will find your experiences with siting helpful. For some decks especially, siting can have a considerable effect.

Rega’s approach to resonance control seems to feature ever decreasing mass with increased rigidity and accuracy in bearing / arm tolerances but that might not be the final word.

Even with the very low mass of your P8, siting seems to matter.



@mahgister,

"In the next week or 2 i will describe my last acoustical device more powerful than any other i used in the past..."


As ever, I’m sure your words will be of interest. Food for thought at the very least.


@djones51,

It's an interesting article which unfortunately highlights the difficulties of preventing human beings from concocting whatever stories they seem to fancy.

It's particularly troubling to me that historical images can nowadays be so easily be manipulated that it can be difficult to gauge whether they have any real veracity. 

Or are they also just stories some people want to tell?
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.
