Hire some strong piano movers, and support your local workers Marc. If you are lucky, they will mess up their backs, and voila you have new customersBill, Stacore comparison is only a mute point in my specific situation. It took a Herculean effort to get them in my room, and no way can I repeat that. In any other circumstances I'd do a careful A/B against the TGs.
I'm only reporting what I hear, and what I hear is very dramatic and hugely musical. Nothing more nothing less.
Having Marc download a app, and make a youtube video ? What alternative universe are you living in Bill ? We have tried teaching him to upload pictures and post links, all in vainMarc - I don’t think it is fair to compare the Stacore to these feet like that. The Stacore platform will be infinitely superior on its ability to protect gear from vibrations - it is just the basic physics of the matter. You can test this for us on a first live YouTube Spiritofmusic test by downloading one of the vibration apps for your phone and placing it on top of your CD player (or anything else for that matter), then just tap your foot on your suspended wood floor in immediate proximity and look at the output on your phone. Repeat with the footers. Guarantee you the ability of the footers to protect your gear from externally induced vibration is many orders of magnitude lower.
The footers might have some use *together* with Stacore as a means of channeling internally created vibration into the footer chamber converted to heat.
As for Daiza. Once again - Daiza is not for protecting gear from external vibration but for channeling out internally induced vibration.
Is that in the category “downfiring” ?
Or “Zu/Zoo lovers “ ?
Yes didn’t Marc hurt himself once while he was performing some serious “tweaking “?The older ones are not as good due to the room, but understand the later ones shot in the new room are supposed to be good, though I haven't seen. Too fetishy for me. I prefer dialogue, but here there is not much focus on the speaker
Scenes on various different platforms, various toys including a perphery ring. In one scene his tube blows up and pierces his thigh.
Vibration Sources Explained.
I just want to clarify several points here. There’s a lot vague and incorrect information flying around here so I hope everyone will bear with me as I try to explain a few things.
Vibration mainly comes from three distinct sources. Ground based, air-based aka pressure waves and internal vibration generated from electronics.
First, ground base vibration can be reduced through isolation. Springs, dampers, hydraulics, and magnets are all great mechanisms. Townsend Audio and Stacore have great videos demonstration this. I’m not going to labour the point here, great job guys!
Max Townsend of Townsend Audio:
Next is air born vibration generated through pressure waves. Here’s an excellent video demonstrating the principle. In fact, if you watch the Stacore video to the end their transducer picks up pressure waves from the tapping.
What Happens When You Put A Speaker In A Huge Vacuum Chamber? Can You Hear It?
Lastly internal vibration generated from electronics here is a nice white paper on the subject.
CONTROLLING RESONANCES IN PCB-CHASSIS STRUCTURES by Tim Williams.
The conclusion of this white paper is interesting because the key is to shift the resonant frequency of the structure and the electronics is to dampen or shift the frequency so it becomes benign.
I’m the biggest sceptic here and I prefer not to make assumptions. Statements like lowering the acoustic noise floor are extremely hard to prove. I have a prisim sound dscope series 3 to measure noise in dacs etc and it’s extremely hard to get ‘real world’ measurements that back up this statement. At one stage I was hell bent on proving our isolation feet reduced the noise floor and they may do but without a proper anechoic chamber and the right lab equipment, no can do. When I started testing our feet I was expecting the noise floor to be cleaner but it wasn’t.
After a long conversation with the Graham Boswell at prism sound, the majority of these issues appear to be amplitude and phase modulation and has very little to do with nose floor. They have proved this with CD players. You can hear differences between two identical CDs in the same player and this is to do with slight imbalances in the discs themselves. The vibration differences then cause amplitude modulation in the laser circuit that can actually be heard.
With isolation devices, you hear a more detailed and clearer sounds because the phase and amplitude are more precise and cleaner. When you listen to a stereo pair of speakers you can really detect the phase and amplitude difference, you may only detect slight amplitude difference from a single speaker though. Our hearing is amazing, we can detect extremely low phase difference down to the nano second I believe, but don’t quote me on that, and why we can hear changes in sound stage for example.
Platforms will handle ground based vibration. But the material these platforms are made of are also crucial and that’s very much why the Panzerholz is so effective. That top plate is also susceptible to pressure waves. Steel is an awful material where vibrations are concerned. You may design the best isolation on the planet but a steel structure will transmit pressure waves through its structure very nicely. Nearly all our hifi component case are made of steel or aluminium which is very susceptible to these external pressure wave.
In summary you need a device that touches the case of your hifi component directly to address air born pressure waves and to make internal electrical resonance benign. Racks and platforms address just one piece of the puzzle and it’s very hard to get a rack home for A/B comparison. Finally, using the right materials is key, Material science is key, aka Tungsten.
