I like hearing about the various music choices but I think there tend to be too many. Makes the comparisons too complex and brief for my simple mind.

Seriously when is he releasing a dj set? Im buying

I asked a similar question. How about some Quadral speaker reviews? Designed and manufactured in Germany and was told, there would be no interest on KZfaq? Hey ho.

Probably with some maths, you would need to find out the natural frequency of your system depending on the mass of your speaker and the stiffness of the ball bearing, then calculate the damping ratio, and then transmissibility according to resonant frequency.

It's a book of his work.

No, I don't. That inner/outer positioning is just for the benefit of the video -- to show that I have both products in house.

Copy, thanks for that clarification John, much appreciated

Whatever Wilson does, it's still a bunch of scanspeak drivers put in a resin box. Meh. What will they call the cabinet next? XXXZYZ material?

I did some Dyns last year but not a lot of audience interest in 'em.

@@DarkoAudio thanks for responding. I know you covered the active speaker which seemed to get a lot of activity. Regardless, thank you

I agree, more Dynaudio!

They are pretty easy to drive.

DIY Kit?

Emotiva makes great, affordable speakers with the same style of tweeter. Talk of quid makes me wonder whether they ship to the UK though (American company)

Actually MTM doesnt mean its d'Appolito... d'Appolito has some strange parameters in terms of spacing and size of the speakers (actually pretty tricky to achieve real d'Appolito). It's hard for me to understand why you would choose those MTM designs... vertical off axis meassurements will show pretty bad cancellation at the crossover point due to phase shift. Nevertheless, this kind of waveguide, with its sharp edges above and below the tweeter will diffract soundwaves from the ATM. Sound engineering wise, its far from perfect, but who would want a perfect speaker ;)

exactly, seems all wrong to recess a ribbon tweeter like that, my MTM's baffle gets skinny in the middle with a dome tweeter to aid dispersion, much more sensible.

I think they are made by Tom Ford. He uses that sideways “T” shape on the front corners of his eyewear.

The cabinet. Still, I agree that given the drivers, the price is outrageous.

I've seen the insides of high priced subwoofers where it's using un branded junk inside and where electronics that should be next to each other on boards are actually placed on a secondary daughter board for cheapness. Some of the pots were literally almost dead and they are charging a fortune for these. The power supplies for somethings are so poor.

Agree. We do all kinds of things to fix speakers to the surface and to isolate them from vibrations, etc. and then we see a speaker that moves and stands on ball bearings. Would like to see some measurement results between the speakers reviewed here.

Think of it this way, if the acoustic energy was already transformed into cabinet vibrations, it was lost already in the first place, and that portion of energy would never have had translated into actual direct sound. What you normally have instead are vibrations oscillating up and down the speaker cabinets, causing resonances, trying hard to find a path to exit. Ball bearings allow that exit, by transforming the movements into frictional heat, instead of waiting for the vibrations to dissipate slowly on its own. The key thing here is that the ball bearings must not flex or morph on a microscopic level, meaning you need to have the hardest, most rigid material possible for a most effective path to exit. Which is why you see companies like Ansuz applying exotic diamond or zirconium coatings to boost up the hardness levels. Standard steel, titanium, ceramic is not hard enough. The ball bearing indents on this speaker don't look perfectly finished and doesn't look like it has any coatings, and likewise for the ball bearings itself - so i don't think it's performing at a very high level.

@@meesmo4 very well explained. Interesting! I think for the level you described, the price will be a lot higher.

A similar principle is used in the products from Iso Acoustics. Their products do allow movement, yet the work and I've heard substantial improvements, even at a Pro audio trade show, which is where their first market was.

If you're just talking DAC then reasonably priced and high quality starts as low as €100-200 nowadays with something like a Topping E30II or SMSL models. I've been very pleased with my E50. The Eversolo is an all-in-one DAC/Streamer/Media server. Gorgeous piece of kit but unless you have a lot of local files or intend to listen to a lot of streaming apps it is probably overkill. Besides, a Streamer + DAC solution might be more flexible. DACs especially have come a long way in the past 5 years. Where it used to be common to need to spend €2000 on a high-end DAC those older models tend to be blown out of the water by even entry level DACs. The chips have become cheaper and there is a lot more competition, meaning prices have gone down significantly.

@@JaccoSW Thank you for your input. I decided after viewing many videos from various sources to go with the Eversolo DPM-A6. We have a ton of CDs and a couple of boxes of vinyl ( I have a Denon Linear Tracking turntable somewhere boxed away) so as storage is MUCH cheaper than when I first copied over the music it's time to do some lossless CD copying to get my CD's moved over to storage in case there is a problem with CD degradation down the road. Also looking at a USB device for laptop, thinking for the RU7 based on some reviews?

Hey, awesome components you have there! Just looked them up on the net. What are you planning to use the DAC for? If you want to play your CDs, I would honestly opt for a quality CD player instead of going the PC+USB+DAC route... Why? CD degradation (real silver ones, not copied ones) should be a non-issue, and audio quality with an old-school but well-made CD player should be still better than a self-made chain of some random PC, USB transport and DAC. ... heard a Rega CD player yesterday at a HiFi show and was really amazed. Good stuff!

Totally different tier, my friend. John didn’t review Mini, so maybe you should ask Srajan with that question.

OK. Maybe John did have the occasion to hear the Mini even without a review. Possible????

forbidden

Then tak’em off 😂 why you complaining? I’d rather have the options to try’em out

Isn’t that much more expensive than this Vc-ones?!

-10 db on the frequency response

The balls help resonant frequencies inside the cabinet(I am guessing aluminium’s natural frequency) to exit. There are other ways to do this but they chose ball bearing mechanism. Usually cabinet materials colorize the sound, a part of designing selection. John mentioned aluminium is close to Mpingo wood sound.

The Sly & Robbie albums?

Yes @@DarkoAudio
