59:23 If change of phase is change in direction and it heats the boundary it interacts with. Diffraction happens most pronounced with a coherent source and the diffraction angle is dictated by the boundary. The most efficient geometrical shape for diffractive phase change is circle. Best 3d shape against pressure from outside is a sphere. When certain parameters align, crossing a treshold in relation to the physics involved, the phase change on the boundary layer (Impedance change) of a collapsing bubble is nearly instant chain reaction, that can only change phase from as coherent as possible (diffraction) to as non-coherent as possible (circle/sphere). The spherical shape acts as a 3 dimensional lens, focusing the mixed phase wavefronts symmetrically, diffracting shorter and shorter wavelengths on the surface as it collapses. The instant change of phase on the impedance change layer releases heat. @JHBrandt That's sonoluminescence!

I could listen to JR all day. His knowledge and enthusiasm for us all to achieve the best from our cartridges through set-up .... is fabulous. Thanks for this.

I have the AC Essentia, Ageto, Kassnadra and Aurora's. I have found my end game system thanks to Stavros.

Hibibuddin has not played the whole kaida. He has ommitted the upaj of the kaida. That is where Ahmedjan excelled. He used to say निकाल किधर मालूम हैं।

Looks like INTJ

WOW WOW WOW, man.....this sessions are insanely vigorizing. It just makes you want to dig it more and more. Keep it comming please. For the ones like me that don't have anyone to discuss this kind of stuff it's life saving. Thanks to all of you, each one of you looks so commited to share information that is so difficult to get FOR FREE that it blows my mind. Really thank you so much for the time you have give us!!!!!!!!! Greetings from Uruguay!

Thank you everyone for this outstanding masterclass; a well spend 4 hours and I picked up a lot of ideas for non-localised sound (mono) playback!

A very nice masterclass; thank you.

When you consider brands like Audio Note (Peter Qvortrup), Pass Labs (Nelson Pass) and Decware (Steve Deckert), their philosophies are built around presenting a musical experience for the listener and from a design perspective, simplicity.

I wish he had gotten to the “simple” things/examples to tame basic room noise

Pt jagdish prasad mishraji amar rahe

can you tell me what app do u use to model the panel? thanks

great info. would love a follow up, including John ;) !

Thank for the vids, please buy yourself a microphone ;)

This is a remarkable discussion.

The main benefit of more than one sub is evening out the modal response.

Thank you for hosting this talk Karthik and thank you Ron and John for your time and your knowledge.

Thanks for the video. At the moment I see that they are clear that they defend that Sabine's formula is not correct for acoustically small rooms. It has been discussed for years but I hope that in the presentation of the papers of his investigation everything will be clear. I can imagine the criticism they will be having. It strikes me that with a broadband porous absorbent panel of only 4" an absorption coefficient of 0.8 can be achieved up to 80-100 Hz. I have already seen that they say that the panel is made with 2 2" plates and each plate with a different density. Can you explain it in another video? Without further ado, many thanks to Mr. Ron Sauro and John Brandt for these 2 videos and to the team that has made it possible to have these guests. written with translator Greetings...

Thanks for the video. Let's hope that in the next video they can fully detail what is related to that 4" porous absorbent panel (made of 2 2" sheets and each one with a different density) with an absorption coefficient of 0.8 at 80 Hz What has been said about Sabine's formula for small rooms is another issue that could be explained more fully. written with translator Greetings

Apne dada ustad ahmad jaan thirkawa ka baj baja rahe hai

\wow, that is revealing about the effect from wind turbines and peoples health

i don't listen to anthony grimani anymore a former at THX well THX real THX days no longer exist even if so what razer THX is joke today this guy is trying to sell $$ and that is what boils my blood . been there done professional projection and this guy keeps showing the same diagrams , i'm out of here as this guy is really starting to vex and boil my blood

Thanks Karthik for the video just missed it

Panditj ke bare me jitna kahu Kam padta hai Mera naman

Man I could listen to Peter ranting for hours, they should seriously consider opening up that pub 😅 Thanks Karthik & Co 👆

I am also extremely Sorry & taken aback to say that such deserving talented singer left us which is nonfilable by any singer of india. And who was totally neglected by the rest singer of india. I don't know why !!!. But I am sure my respected & beloved sangeet guru was neglected politically by all other classical singer & more. I am alas that what a low mentality they are carrying. I think they should take talim from pandit jagdish prasad. I am telling all these as a student of such talented singer.as I had taken classical talim from him . Sorry......

I met Mr. Qvortrup in the eighties and bought an Audio innovation amp, Snell speakers and Elite Roc Still sounds great 40 years on.

THX Joachim for such videos, great explanations you share for free from your experience.

Fantastic perfomance 👌🌹

অসাধারণ তবলা লহরা। 🙏🙏🙏👍

Wah Pundit g , kamaal hai.

56:47 - The Numbers Game - why THD is irrelevant to good sound

Karthik sir, I'm from chandigarh, India and am into hifi audio, have been into analog for an year now, my audio journey has been 3 yrs now, I'm 26 and after finding audio note through u channel and now I'm really into tubes, valve amps being so expensive I can't afford it, so I was thinking of making a budget one with Hammond parts, but nothing is available from inside India according to what I've found searching the web, sir can u suggest any way to source parts, if u have some old parts I would love to get them from you, I'm a straight person and I speak only from the heart, you have really changed my point of view thankz a lot.

Some people give the sound reproduction of music more importance over the actual music. They spend enormous sound of money on the audio equipment. Probably vanity and an obsession in seeking status.

Wonderful, God of Tabla 🙏🙏

Everytime i listen pandit Ji's rendition always mesmerize 🙏🙏🌹🌹🌹👌👌👌.

He was a great singer , even better than bade gulam ali as a thumari singer.

Bayan bahut gahra rakha hai ❤️❤️❤️ hamesha nahi hota esa

1:20 Finally!!! I have an answer as to wether "better" PSU's on a motor SOUND better. Thanks!!!

এটা তো নিজামুদ্দিন সাহেবের পেটেন্ট ছিল। চমৎকার শ্রদ্ধাঞ্জলি। কি মিষ্টি সুরেলা হাত। দিল্লীর বাজ এভাবে রপ্ত করা!!!!! 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

Wah Guruji. .Pranaam

Laajawab panditji.

He is not ishan

The grey eagle of the audio world.

Always a pleasure to hear Peter Qvortrup speak. Aside from the magnificent work he and Audio Note do for music, it is just great - and rare these days - to hear someone who is an original and clear thinker. Thanks for this Karthik, I really enjoyed it.

"The speaker and the room are one unit". Excellent advice on base!

Peter is so right! The #1 purpose of recorded music is that we can go back in time and re-live older eras, and experience talent that has long gone from the planet. It should be the industry's top priority to keep compatibility on the long run - if they create the habit to break with the past, then the future will keep on breaking with them and what is recorded today will be just as outdated and thrown to the long forgotten bin 50 years from now.

As a scientist the Peter may be right but as a not rich man i can't sadly afford yet his stuff to verify what he is saying. All i know is my own experience in the low tier of audio equipement and sadly it doesn't always shows the Single ended triode as the winner. But i'm eager to learn, anybody knows where i can go and listen to those amazing stuff ?
