Thank you!

I am jealous :)

Goid job! I know, it is my Italian blood that tricked me...don't worry I have been crucified all over for this.

Crazy prayingmantis You may want to try a wood platform such as Maple. I find that Marble or any very dense substrate seems to ring like a bell at certain frequencies: wood seems to not ring at all. I would be interested in the results of your experiment.

Blind listen tests are unreliable

blind listen tests are extremely bad at preserving intuitive preconceptions

Thanks John, probably because a lot of people do not believe that vibrations can be harmful to sound reproduction...

@@anadialog Or you just can't please everyone, all the time...oh well, the rest of us will enjoy and benefit from others.

Thank you very much George!

Very interesting. Thank you for sharing! Did you find significant improvement in your Technics SL1200G? I have the same TT...apart from this, thanks fir sharing!

no I only switched the feet and the cables. especially the ground cable that came with the TT seemed to be of very poor quality, very fragile. The standard neoprene mat, in contrary to the cables, is doing its job very well, has great vibration dampening properties. I added plates made of sorbothane with glass inlays under the Isonoe feet though, because I live in a house that is like a low-freq vibration conductor. Sorbothane is very good for decoupling lower frequencies, however it's not really suitable for decoupling higher frequencies.

these improvements only make a true improvement when playing music with much basses and things like feedback from walking around, closing/opening doors etc.

@@anadialog Recently, I might have found the best SL-1200G upgrade possible. The KAB TD-1000 liquid tonearm damper. It not only reduces vibrations in the tonearm significantly, but also lowers and decreases the effects of the tonearm resonance frequency. So a bigger range of low and high compliance cartridges will suit the tonearm very nicely when the damper is installed. It also helps tracking warped trashy records. At first I was skeptical, but when I realized this damper has dynamic damping characteristics instead of just giving resistance to tonearm movement, I took the plunge. It certainly is worth a try and is very affordable! Vibration dampening feet and mats are great upgrades, but this damper is... amazing! 👍

How cool! I did not know about this...going to try it ASAP! Thanks man, for sharing that!

Thank you Ivar! Yes, I agree. Vibrapods are great also under digital sources. This is true also because this typologies of sources is VERY sensible to vibrations, perhaps even more than turntables!

Hi Tommy, yes, you are right. I am mainly Italian so I mispronounce several words...thanks!

I was just joking, I happen to really like your channel and try not to ever miss it! Thanks for all you do!

Thanks, yes, in the end I am mainly Italian so I do these pronunciation mistakes...sorry about that. I am getting better now! ;-)

Cool! Thanks for sharing!

Cool!

No it doesnt the energy transfer is by mass coupling and the point has a very small surface area so it efectively reflects the vibration back up the cone of the spike, as well as down to the footer. Generating a small amount of frictional heating at the point of contact, to disapate the vibrational energy.

Hi there, I agree and everything but I disagree on the CD. It's not only a matter of reading but of converting, interpolation and handling the signal. People tend to think that digital is just 1s and 0s but the reality is much more complex and full of issues that filters mask somehow but not perfectly and nit always effectively. Check the video DESCRIPTION of this video where I added some scientific evidence of this: kzfaq.info/get/bejne/bqmEd5l2zLGrZac.html

@@anadialog Thank you for your Replay. As always, the matter is not black or white, but rather how to quantify the subject. On a CD, assuming correct data reading is done, all mechanical vibration that might affect the reading become non relevant. The Section that might be affected by vibration is the analog section from A/D and on (this include also the crystal that generates the A/D PLL clock) . I estimate that this section sensitivity to vibration would be no more than that of a standard Aux level Transistor Preamp. Much less than Phono Pre Amp section because signal level is 100 times higher, and much much less (1000 and more) then mechanical Analog player like a cassette deck, and further lower then a Turntable which is the most sensitive part for vibrations. So to quantify the sensitivity according to the above estimation, taking a Turntable sensitivity to vibrations as reference 0dB, a cassette would be -10db, phono pre amp - 20db (tube) - 30 dB (transistor), Aux level -40 dB. Power amp: -40dB to -50dB. At these levels, it is possible that the unit enclosure vibrations might generate higher audible noise than the electronic noise it might produce. The Above dB levels are not real numbers, are just to give some numbers behind my statements. It can be tested by applying a controlled level mechanical vibration on the product enclosure and measure the output signal generated from the device. You would want to prioritize the anti vibration treatment according to the unit sensitivity to vibrations. Thanks again for your replay, I do appreciate a lot your videos and my comments are for the purpose sharing and improvement of knowledge.

Absolutely! As I always say, this is a dialog, not a monolog! The important is that we all have a constructive and polite attitude, like you. Not everyone has that.

Too many vids give intro which title alone gives already. This video didn't say much at all, waste of time.

Maybe you know all about vibrations but a lot of people ignore completely the topic, hence this IMO is a good starting point.

Ernesto you are very welcome!

Thank you!

Hi Donald! Could help! The best in this case is to mount the soubdbar on tye wall but I bet you can't do that....

@@anadialog , I've read someone's suggestion (in the comment section under one of your other videos) to mount a turntable to the wall for improved sound as well. Why is that? What is it about a wall that improves sound over isolation in any other way? Thanks in advance.

Well, maybe that is not such a good idea after all. It depends. If the wall is a supporting wall, with a high quality decoupled shelf then it may have sense...must also be precisely leveled..

Lol

Pathetic. Use the international space station zero g or it’s just a hobby.

Nice! I love isoacoustics. The completely changed my loudspeakers performance

Ci sono altri prodotti isoacoustics che io reputo il top...guarda bene I modelli e quello che trovi usato. Altrimenti I soundspikes non sono male...

Grazie! Li ho avuti, sono dei buoni piedinia niente di eccezionale. Per me le isoacoustics sono superiori.

You could use the Isoacoustics Orea, the have rubber beneath

Hi TheTarrMan, good job in refurbishing you turntable! I would not recommend using a sponge since the foam pushes upwards and all turntables have different weight at each corner. You would be facing a strong unbalancing. A cheap way would be to use the "Deflex/Milty Foculpods", or the "SorboGel Qfeet" or simply some "vibradopds". More fancy and effective solutions would be to replace the foots with audiophile grade feet like the "Isonoe Audio Isolation System" possibly together with the "Isonoe sorbothane Isolation boots". The foot replacement is obviously dependent on the presence of screw holes on the back of the chassis and their dimension (M8, M6, M4 etc.).

I hear you! I got mine used. For what use? Speakers or other?

Not of decoupling is done properly because it absorbes the vibrations.

Hi Cesarin321! Sure, that is the AUDIO PHILAR double anti-vibration platform (audiophilar.com/en,double.html). I just want to underline that I do NOT have direct experience with this product. I just inserted the photo because it was a good example so for this reason I cannot recommend it. In any case, any anti-vibration platform of decent quality will do the trick. Otherwise you could substitute the feet (if possible) or buy a good quality hi-fi rack.

thanks a ton !!!! sadly i don't have space for a rack... so my options are limited..

Try Auralex Iso-Tone, it's not super cheap but one of the cheaper isolation platforms for turntables. Just check that it is the right dimensions. You could always level under the feet of the turntable, with cards or some sort of riser.. saves having to level the floor sometimes xD

thanks for the advice

+cesarin321 thank YOU for watching!

Dave Jones, Yes! This is a very intelligent a wise comment. I completely agree. I must admit though that sometimes the results are so evident that it is clear and obvious to anyone as the Gaia Isoacoustics of you are coming from absolutely nothing under your loudspeakers!

At the time of this video i did not purchase yet the Gaia isoacoustics III. They are quite impressive under loudspeakers...everything just opened up!

I don't know them unfortunately

I have both. The superspikes are just good spikes kept in position, that decouple. The Gaia has a complex dampening geometry. Its a totally different principle. IMHO the Gaia does not have rivals out there.

Hi Kamal, the cases you describe are in fact probably the more subtle in terms of quality increase. I must admit that a friend of mine inserted high quality decouplings under my mains filters and there was definitely a benefit, nothing dramatic obviously. After, I did the same with vibrapods and at that point I also must admit that there was no effect...cables? That is a little too much for me although it is a good idea to keep them off the ground.

Solid state devices resistors transistors capacitors well all vibrate to a small amount in time with the alternation current passing through them- this will also translate to parasitic vibration at the natural phyical resonant frequesnt of the device. These vibrations can be transfered to the casing of the unit (depending on it manufacture) hence the noticed effect of damping on some equipment. It's really only and attempt to overcome some poor engingeering implimented due to price-point/profit. Dont get me started on Thermionic tubes =microphoics big time! But are put on prowd display on the alter of audiophilia. Usually in the center of much vibration and airpressue change. usually negating anything done with vibration control elsewere.

Damn autocorrect - sorry for the spelling mistakes.

Thanks Adam!

Cool!

Your English is fine.

Depends for what!

@@anadialog Amplifier

Probably an isolated platform from Isoacoustics or Townshend would be the optimal solution!

😆

I know, I always mistaken that word...I am mainly Italian so I I mispronounce several words in my vids. Sorry about that.

Ha no worries enjoyed your video. Cheers

Welcome aboard!

I wander If those rubber deflex pannals are still here that go inside the speaker box back in the 90s ? I never had any , they were £15 UK each

Hi Dale, as mentioned in the video, solid state electronics suffer much less than all the rest of the system. Nevertheless, even solid state can encounter microphonic issues generated by vibrations. One of the weakest components are the capacitors, which unfortunately do generate some microphonic distortion. Here are some scientific articles and renown manufactures' papers that describe these issues (I underlined some passages): Scientific article: www.dropbox.com/s/sgd9bszsbkqvp6a/Capacitors_for_Reduced_Microphonics_and_Sound_Emis.pdf?dl=0 TDK: www.dropbox.com/s/3o72zwvhaz7eyag/31_singing_capacitors_piezoelectric_effect.pdf?dl=0 Mundorf: www.dropbox.com/s/dsxj3v43d86qfna/Mundorf_Fidelity_Components_Catalog.pdf?dl=0 Infratec: www.dropbox.com/s/99wxmwvajxtlyo7/infratec-application-notes-microphonic-effect.pdf?dl=0

+Tbonyandsteak, Yes...hard to implement though...

+Tbonyandsteak , Yes! Hard to implement though...

I know!! Too late...

Hi, well, it depends where...I do agree that there are more effective solutions...

But they look cool. LOL

True...;-)

+twochaudio twochaudio, serious Reel to reel is upcoming!

It seems, but it isn't. In the video description you will find a peer-reviewed scientific article that explains how capacitors, present in all electronic machines, are negatively influenced by vibrations. And that ia only part of the problem. Yes, in some cases they do implement solutions to reduce vibrations but only very few do that because in order to do it properly it is quite expensive. For instance, one of the main differences between the Technics SL120GR and SL1200G are the special damping feet.

@@anadialog The article cited discusses the a piezoelectric effect of capacitors when placed under electric field i.e. they vibrate locally on the PCB when exposed to an electrical field. This isn't something that chassis feet would be able to address. Nor do chassis feet address how well capacitors are attached to the PCB or how well the PCB is attached to the main structure of the unit. I'd be interested to know what frequency and amplitude these isolators address and see an FFT plot of the sound with and without these isolators. The Technics SL120GR and SL1200G are turntables, which I didn't cite as examples for wondering how physical vibrations influence the sound. I understand the sensitivity of turntables to external mechanical vibrations as they use a balanced arm to delicately hold the needle onto the record withins a small range of forces and use the indents in the records surface to generate sound.

The issue is real just Google it and you will find dozens of articles. Here is an example: eepower.com/technical-articles/vibration-proof-capacitor-technology/ Don't focus only on PCBs all electronics and mechanical gear suffer from this. A decent isolation will improve performance.

@@anadialog That article you linked centres on the durability of capacitors in an automotive environment, e.g. cars. It states nothing on the impact, if any, of accelerations of a fractions of those experienced in an automotive environment on sound quality from a home sound system. I'd need to see FFT plots of with & without isolatores before I could be convinced and it would be interesting to see how the Vibrapod Isolators at £22 for 4 compare against the IsoAcoustics Gaia-Titans at £600/4. To me it just seems like a way of selling small, shiny bits of metal for an exorbitant price.

Yes, because it is an environment with vibrations. There are dozens of articles out there. I am sure also with some measures. The problem is real and at more levels. Happy listening! :-)

Yes, I am mainly Italian so I do make some mistakes. Sorry about that.

If this communication was from an English co-corporation or a scholarly representative I would agree; but demeaning a well-intentioned cascade of information by someone speaking in their non-native tongue is a cheap shot in my opinion.

Interesting!

Hi Campbell, you are perfectly right...in my defense I can only say that despite my accent, I am Italian...so you are going to notice a lot of mistakes in my videos...sorry about that!

No probs, I enjoy your videos.

Hahaaaa I thought I was watching a video about fishing for a second
