@@lekmannen9990 thanks. True about directivity. It will be better to use two smaller (square) grs planars per side and angle them inwards to the left and right a bit. It will broaden radiation

He has had many speakers and he also has the Magico Q7 and almost all is very high end and he wanted to listen something cheaper.

@@timschutte3961 compared to the Q7s almost anything of human seems like a toy High end audio is addiction It is impossible to go back without feeling pain

@@kendavis3604no $$. Jay has 500x more

@@lexiconthx1 sure, jays preamp does not have $100k parts, and also ps audio fr5 dont have $2k parts. All im saying is, if matching basic speakers with ultra high end electronics makes sense, the opposite also would be nice, to match $200k speakers with chinese amps with sparkos opamps and with fiio r2r dac for $160. It feels like many are affraid of such test? For example, ive heard $30k speakers with $1k yaqin amp and result was awesome.

@@SonicJourneys-lo1rk Andrew Robinson does exactly that with a lot of his reviews. He will pair a set of speakers with different receivers, separates etc. He tends to find that he gets the most out of a set of speakers when they are paired with better electronics. Key word here is better not necessarily more expensive. I personally think Audio Research preamps and amps sound just as good as the Boulder that Jay has. for example. I'm honestly not familiar with yaqin equipment so I can't comment how the Magico's would sound with their amp. I think one of the XPA amps from Emotiva would drive them really well though especially a set of XPA-DR1's. I personally think Jay was trying to show us though how good the PS Audio Speakers actually are especially for the money.

@lexiconthx1 agree on all points. Or Accuphase instead of Boulder. Even AudioNote amps can be bought for around 15% of boulder preamp cost, not including gryphons cost. But jay doesnt like tubes. Anyways, Jay has to explore other gear, as it could get boring with same type of equipment, esp when he produces 400 videos a year.

@@SonicJourneys-lo1rk Accuphase makes really nice equipment. I was also really impressed with the AudioNote room at Axpona. They had a really great setup went back to that room many times. I'm also lucky that I live close to Quintessence Audio so I was able to hear the Audio research gear and boulder gear in their listening rooms. I could see myself buying audio research but not spending the money on the boulder. The boulder sounds great but not worth the extra money to me over the audio research. Never got to hear the Gryphons because they never have them running at Axpona. If they are so great why do they go and not demo them?

I don't consider it accurate to say that PS Audio developed the speaker drivers that they are using. The type of drivers that they use have been on the market for a long time. Like most manufactures they probably used pre-existing drivers. They may have tweaked some parameters of the drivers and have them manufactured for them. However, considering these bookshelves use a 6th order filter and are only 83 db efficient hints at the probability that the designer used drivers that didn't match each other well. If one is developing their own drivers the goal is generally to match them as close as possible to maintain a flat frequency response and similar polar output at a crossover point that will allow high power handling to protect the drivers from damage or optimally to prevent high distortion levels at loud spl. I have not heard these PS audio bookshelf speakers. They may sound amazing for the price but looking at the specs it appears as though the goal was to use some of the drivers from the flagship to maintain a family look and not develop new drivers to reduce cost. The drivers used probably do not match well so a high order filter had to be used which means cheap parts had to be used for that because of the high component count. With high order filters there is significant group delay, phase shifts, reduced efficiency, and dynamic capability.

​@ninjareynolds You really don't know what you're are talking about. You're just hunting for viewers. It's sensitivity not efficiency. Efficiency is expressed as a percentage, sensitivity can be expressed in dB. As has been suggested, build your own speakers and do your best to review and sell them to your viewers. Speakers with low sensitivity is usually the result of padding down to extend the lower frequencies and the result of a very small enclosure. You can't defy physics.

@@carlosoliveira-rc2xt Ok, well you're wrong. I actually do know what I am talking about. Yes, sensitivity is expressed in dB and is a measurement parameter for the acoustic output reaction of a driver when provided an electrical signal of a specific wattage or voltage rating. Efficiency is a measurement of how much power is wasted within a speaker system compared to the sensitivity of the individual drivers. I don't care about views considering I don't have a channel. I design and build my own speakers. I know physics can't be defied which was the entire point of my post. In simple terms a speaker system can only meet 2 of 3 targets as it relates to size, output capability, and low frequency extension. Usually the reason high order filter networks are used doesn't have much to do with enclosure size unless a person is putting a high pass filter on the woofer as well. High order filters are used because one is attempting to use drivers up to their extremes where they get close to their max power handling capabilities thermally or mechanically, beaming starts, destructive non linearity of diaphragms and significant resonance issues occur. There is obviously a great deal more that goes into speaker design than I am going to put into a youtube comment. I'm not going to go through all of the details to prove to some random stranger or attempt to be perfectly precise to prove to a random stranger I do have knowledge in the area of speaker design. I'm not a professional, and I'm always learning. Like I said, those speaker may sound amazing however the fact remains that many major compromises had to be made to use that driver combination together. It's not something I would do for myself. I'm designing a speaker system at the moment using similar planar drivers that PS Audio used in the FR30. I'm planning on it being a 4 way with the hopes of it being partial dipole and it will require a balance of compromises with a more complex filter network than I'd like to use.

@ninjareynolds You are some kind of obtuse aren't you? How can anyone take what you say seriously when you use "efficiency" to mean "sensitivity ?" If you knew what you were talking about you'd be embarrassed every time you say efficiency instead of sensitivity. All speakers are inefficient devices with most speakers being 1% efficient and the biggest all horn speakers being 20% efficient. You see, it's expressed as a percentage not in dB. Efficiency - percentage Sensitivity-dB You can pretend to know what you're talking about and feel free to cut and paste anything I have stated here, you know, to appear knowledgeable.

@DrBroncanuus - Explain how your ir anyone else’s idea of a cheap amplifier can damage the speakers 🤡

@@Eric-z6f If you need to turn up the Vol. then degrading the signal to noise ratio thus sending too much noise to the tweeters could destroy them.

@@DrBroncanuus Kool-aid. That amp has solid signal-to-noise ratio across the entire bandwidth up to 200W+ into 4 ohms in monoblock mode.

@@ConorHanley please specify what do you mean by "open design"? Ive selected the drivers to have the least problems with crossover, which is first order, active. The other goal was to have the lightest membranes as possible. And cabinets made from organic materials.

@@bygrace2683 No brand. Its my own construction, active crossover. The sound is spacious, dynamic, often majestic and very fast. Neutral tonality. And i dont even use good DAC or streamer.

@@tofffsymagic1099 thanks. My own build. Woofers from SB acoustics, full range but they drop from 10khz. So i EQ them -12db at 8 and 16khz . Crossover is 1st order at 2600 but can be at many other points. Tweeter is planar which has good output down to 300hz. Digital crossover, bi amped. Plywood cabinets with slate on the walls, like a tank. I think with 10 in passive radiator bass could be even better

@@jaymorin7131 I mention Ohm.

I have Ohm Walsh and I love them ❤

@bengtekman8616 congrats.

Not true, Mirage made highend omni directional speakers which i own for 20 jears and still love them every day

@@robertstart2577 Yes they can be pleasant if you want ambient relaxing sound, but they can never reach the clarity and accuracy of a regular directive speaker. The room reflections just blur up the sound and there's nothing anyone can do about it, short of heavily acoustically treating the entire room. And that would mean the omnidirectional speaker would lose it's main design feature: reflections.

Lllllets get ready to rumbbble...

@@antonsyd7077 thanks for clearing this issue. such coherency is a trade off with high freq extension and distortion at high spl. Perhaps transparency and air also. Clarisys has entire range covered by ribbons, so as Alsyvox. thats hard to beat. I bet AN doesnt want to go multiple small woofers way...

@@CzakNorms-em8nw grs planar and SB Acoustics 8 inch papyrus woofer. Alternatively i could put Scanspeak glass fiber 22cm. The unique thing about such driver combo is that crossover can be set anywhere from 700 to 7000Hz

@@thelastofthedinosaursYou rise good points here. Ive heard kt88 in Unison Research amp and to me they sound spectacular, despite that it was in too small room and with box speakers not open baffles, which i prefer. Check latest sub from swiss SoundKaos, ripole with cabinet made from stacked plywood. I agree that sub should improve clarity of AN woofer( less intermodulation distortion), thats why i think strongest competition to AN is Voxativ with their Ripol sub and extremely good fullrange driver. I would however cut voxativ at some 5000hz and add raal tweeter

Sound Kaos seems like a real boutique brand. They dont even have an amplifier and a crossover for their sub yet they say on their Website. Wow. Fezz amplifiers should be quite good and worth the money.

​​@@SonicJourneys-lo1rkthe voxativ sub is 29000 Euro 😳

​@@SonicJourneys-lo1rkWith a normal sub like REL you will not improve distortian because the speaker will still play the low frequencies as I unverstand it.

@@thelastofthedinosaurs really? I see 12.5k usd for 1 unit on their page

@@2madamimadam290 Yes, tone is important. Transients also. No ringing of the cones and cabinets. And a proper amplifier. While audio note wont beat the dynamics of 105dB horns or space of MBL, they make effort to sound as natural, as true to life as possible.

@@Robert-id9jx the price is veery high. My est. Is you can diy similar speakers for around $40k
