Dear Paul, thank you so much for letting me understand the limitation of TOSLINK. I just realize that TOSLINK - 44.1kHz to 96kHz 16bit, 24bit COAXIAL -- 44.1kHz to 192kHz 16bit, 24bit, DSD 64 Before I think TOSLINK better than COAXIAL because it is nosie proof and much cheaper cable. Now I aware that TOSLINK can only handle upto 96 kHz / 24 bit, without DSD playback capacity. Perphas I have to flow away my optical cable and switch back to coaxial digital cable again. Thank you Brian

It would be so funny if you guys make a little "screen saver" for the P20 or a cup of coffee rotating around as if in a microwave!

Excellent video Paul. BTW, opto-isolation is regularly used to enable computers to safely control powerful and potentially dangerous equipment that run high voltages and currents that would quickly fry them if anything untoward occurs.

If I may be a bit curious and ask all of you: Would you hear the difference between a 48 kHz toslink and a 48 kHz AES connction? Or 96 kHz if you like.

MR PAUL I wanted to ask if you would recommend a different amplifier to drive my 12" DVC subwoofer/s in my car than a d class mono block amp?

You are the King of Digression my gawd

I have swapped out my standard average Toslink fiberoptic cable with a CHT Solutions product and I could tell the difference between the two. Brightened up and slightly louder than before. This is used to connect my Onkyo DV-SP500 DVD player with my Denon AVR-3808 receiver which powers Tannoy Revolution speakers. I'm happy with the outcome.

There is some serious audiophoolery here. I think unintentional. TOSLINK transmits at 125 mbits/sec. It is not even breathing hard at 192khz/24bit, even consumer grade and often with cheap plastic optic connects. So for hifi stereo great. For the new Dolby surround for movies it does not have a standard past Dolby Digital 7.1. So, you need HDMI for the latest DD HD or DD+.

Thank you for explaining why I was not happy with the Toslink connection from my CD to my pre amp. I thought the optical link should have been superior to cable and it wasn't in that case.

Me too, love the design of your products.

Hai My Speaker optical digital audio in available but my led digital audio out only how to connected

Exciting information. Great innovation

Are there optical for music, and optical for movies? I purchased the pearl one from AQ and sound so clear and clean but lacks bass compared with others

hi Paul I really enjoy your video. I never miss any video you upload. Can you please make video on hdmi vs optcal cable whichi one is better ? thanks a lot

Great video, love it when I learn more than I was expecting too. Keep up the good work.

optical is very good connection if you have 2.0 system

I've seen digital reinvented so many times at very high prices when existing technology far exceeds many of the high end solutions. The TOSLINK has issues as other than the plastic fiber. The rest of the product best resembles a TV remote control with a 40 KHZ subcarrier and limited in bandwidth by multipath and reflections in the cable. Optocouplers have their own issue when used without line transmiters and receivers as is the case with MIDI. (yes MIDI is optically isolated) MIDI is limited to a maximum of 50 feet at a baud rate of only 31250 HZ. This is due to the cable capacitance and non linear LED load on the far end of the cable. DMX512 for lighting control has much greater range than MIDI because it uses a balanced line transmitter and receiver with a cable termination that matches the impedance of the data cable. DMX-512 can go for 100's of feet at 250,000 baud. DMX 512 is also optically isolated as the receiver drives an opto coupler to the dimmers in the dimmer receiver section. For MUCH higher data speeds without optical is transformer coupled at both ends of a data cable with the cable terminated into it's nominal impedance. This solution is cheap, everywhere, and very high speed. For carrying packet data it is used for Internet to connect your router to your modem and possibly desktops, game consoles, etc. If you simply used the cable layer technology for high speed data transfer, you wouldn't hickup at 96K data rates, but blow past 100MHZ on a cheap CAT5 unshielded twisted pair cable. The technology is there. It is 100% galvonically isolated on both ends of the cable. You don't even need to use IP data packets and use something with extremely low jitter and common system data clock. Why people re-invent the wheel to go at much lower speeds at much higher cost absolutely astounds me. Use the proven physical layer and send your data stream.

Can the PS sprout take RCA cable or does it have to be optical cable only?,

I'm excited to hear about the TS-DAC, Ted is brilliant and giving him creative and financial freedom is exciting to think about, what's the ETA for this dac?

Posting this if it helps. I had static coming from the adapter Toslink from tv to old receiver and I solved it by programing the audio options on the tv by pressing tv+ optical option just optical gets static. Hope this helps.

the cables alone don't eliminate noise. they just can't pick up noise but the noise that's already in the signal is always there. quit thinking about eliminating noise, it's not possible. you can only prevent noise from getting into the signal in the first place.

I wonder how galvanically isolated USB interfaces compare in regards to noise removal, such as in Schiit Audio's Unison USB.

i run toslink from my mb connection on my computer to my klipsch heratige " the fives" and sw121 sub set up and it sounds awesome for a 2.1 set up

Use the Audioquest Optical Forest on my Cd player.. It's really good, got it for free from my hifiklubben store.

Optical toslink cables itself normally go to 192kHz in my experience. But a older reciver etc can be limited to 96kHz. My PC can sendt out 192kHz via toslink optical but my older reciver can only take 96kHz. So it seems it mostly depends on the equipment and not the optical cable itself.

I love your non-answers!!!

"usually limited to about 96k, so if you want to do high resolution audio, they are not a good way to go.." So I guess 96k isn't considered hi res anymore? Ha!! ok....

I just want to make a comment on the cost of a DAC since it seems to be a source of ridicule. As someone who spent $4,000 on a Koetsu phono cartridge back in 1992, the equivalent of $7,000 now, I appreciate the value of the front end of a system. The two most important parts of the playback chain are the transducers. That is, the source, be it cartridge or DAC (it's not a source if it's not yet analog), and the speakers. Spending a lot of money on amps and cables is a waste if the first and last stages are not right. My turntable system, if you could still buy it, which you can't, would be around $15,000. My DAC, which you can still buy, is also about $15,000. My DAC is the equal of my turntable, and this is the first time since digital was introduced that I can say that. So, Paul, go for it. Make the best DAC you possibly can. (And the best speakers too!) Then take some of that technology and trickle it down to the more affordable DACs in your line. Not everyone can afford the BHK Monos. That doesn't mean you shouldn't make them.

This needs to be said Maximum recommended length: USB 16ft 5in Ethernet 100 Mbit/s 100 meters Fibre 100 Mbit/s 2 km (100BASE-FX)

Computers, or desktop computers are extremely noisy AC wise. Considering everything inside them is DC voltage. Take a non-contact AC voltage detector and within 2 feet it is going nuts.

The quest for sonic nirvana never ends.

Was the signature DAC ever bought to market? I don’t recall seeing it? What happened? @psaudio

So, Toslink optical S/PDIF is limited to 24/96 . What is IEC958 limited to?

0:56 Hey! It's Cal Worthington!

Plastic toslink cables perhaps were not made well enough in the early days when it was first introduced (early 80's) but since then manufacturing techniques have made them to be very good transmission lines. The SPDIF protocol meant for consumers itself is the limit on the specified data rate, not the cable itself. It was designed before all the multi-channels we now have. The similar professional standard AES/EBU SPDIF can use optical cables and be any data/sample rate. They do not use plastic cables simply because the loss is greater over a studio's typically longer runs. The 2, 3 or even 4 feet normally required for home audio installations is NOT a problem with plastic optical cables.

Paul, big fan here of your videos and your products, though i cannot afford them, and now two new exciting products coming up! But $20k for a DAC?? Anyway more power to you guys.

can you please help me fit my home theatre in my room perfectly

I find toslink cables make a difference, in a more expensive cable there are less reflections and that creates jitter (imperfections in timing) and I hear stopping of notes way clearer with a better cable, just don't buy $2 toslink cables. Also, the most dramatic difference is found in SPDIF sources, not all sources sound the same. You may find a bluray player with toslink out sound different than a bluesound node 2 or a chromecast audio. It also can be differences in the transceiver that sends the light. Toslink is a way to cut distance between 2 devices, if the source device is crap, it won't come some magic at the other end.

How is your pricing actually working? You are going to charge (in UK) roughly £25.000 for a DAC while 2 BHK 300 monoblocks are £30.000 (+ £6.000 for BHK signature pre-amp)? I thought that Chord Dave at £8.500 is insanely priced but you beat them 3x!!!

2:53 lol

Keep in mind that there are cheap optical and high quality optics Cables

You are awesome 👌

watch the signal if you bend 'em

Yes Ive mistaken it with microwave 😂

That one expensive microwave oven. I'll take one :)

I wonder why they still use optical connectors. Never any good sound from them. Your new product with separate digital and analog on better quality optical connection sounds interesting. Only I suspect the analog part of it still be the most critical component

If you wear hearing aids------ none of this matters.

If that P20 could speak.

Might be 20k, maybe 30k 😆🤣

A few points here about fiber interfaces. Agreed, TOSLINC is junk. It's a plastic fiber. While it does offer galvanic isolation, it's rare that any consumer system will actually benefit from that. Too many other ground paths to make much of a difference. Next "half a mile"? yes, multimode fiber can easily do that. Go with single mode and you get 50-100 miles! So in your new product just use a Multimode SFP module and that will keep the costs down. Take advantage if the billion dollar IT industry! They are what makes these devices affordable in other electronics applications. But one problem with fiber is jitter. Fiber interfaces inherently have higher jitter than electrical interfaces. It's going to be trade off between jitter and noise in your upcoming split DAC. Due to all the other necessary ground paths, I would probably go with an electrical interface like balanced I2S which you have successfully implemented over an HDMI cable. But hey, I'm sure you will test both and pick the best option.Just keep in mind, fiber is not the panacea many like to think. It's great but not without some of its own issues.

geez, 1600 buck for a power cable? maybe the price is so high because virgin redheads essamble the cables on fullmoon on every first saturday (when Jupiter is in sight)

Not sure but if you want the cables money definitely seems to eliminate out of your pocket to get them lol

Eat A Bug?

No, they don't!

Analog switches inside a server? I don't follow you. Do you mean transistors operating in their linear region? Or the idea that 'digital' is more of an abstraction than a physical differentiator? I have often wondered why optical links haven't caught on more in consumer stuff. Enterprise computing equipment use them quite a bit, even for relatively short runs. Obviously they're not concerned about audio fidelity, but bits is bits, and noise is noise; too much of the latter can make getting at your Oracle database just as difficult as getting good sound.

30,000 bucks at last digital Nirvana are you sure If I buy this I will never to buy any else ever again that's any better??

I was amused at the thinking behind turning a digital cable analogue, it seem PS Audio want to change the modern understanding of why digital signals have better integrity than analogue on its head; probably to convince their analogue nutters to buy the system), PMSL!. "We lower the highs to they dont saturate"), but thats the whole point of digital Paul; so the 1's and 0's are as wide apart as possible preserving signal integrity. That guy obviously knew electronics very well at the start; then as the years passed he has listened to so much drivel hes actually started to believe it.

Looks like a printer to me..

Looks like a microwave oven! 😂😂😂

So how is analog box pure analog if ur sending a digital signal to it?? Lmao

Plz replaye

Just nonsense, my streamer happily sends 192khz via optical to my DAC.

Mmmmm mamma mia lmaoo

Ok, so TOSLINK cables are plastic and not glass fibers? I don't see how that can work, but for for the sake of argument, let's go with that assumption for the moment. So here is the question: TOSLINK are the only optical cables available to my knowledge for audio......unless you know of others. So are there other optical cables available for the consumer? Good luck selling those $30k pieces. I would not want to be the manufacture investing in gear like that in this economy or what it is about to become. Diminishing returns city!

Paul got sidetracked once again hawking $20K amplifiers and DACs, this time. I don't come here to gush over your gear rather the technical details that have -0- to do with PS audio. TOSLINK is still around, BTW. XBOX

Just FYI, both coaxial SPDIF and AES3 are both inductively coupled at both ends. There are no ground loops as no grounds are shared. Both schemes as well as optical SPDIF are fully digital and thus immune to noise. Balanced AES3 just improves the noise immunity with respect to the digital cliff - meaning longer max cable lengths. So no, optical does not mean = higher quality.

Please don't eat a bug.

30 K $ DAC ? LOL

Do I win a sprout for being first?

Wait..... 🤔..... Wut ???? Analog logic ???? You mean quantum computing technology, yes ? At the absolute cutting edge of technology.... I'm impressed ! But no....😏 I saw what you did there ! 🤗

Skip to start 1:40

Now I am starting to get very annoyed by Paul. He is constantly selling [yes, he is selling] equipment that is WAY beyond what is necessary to produce absolute high-end audio. He is talking about PS design approaches that produce differences that can ONLY be measured by top-end electronic diagnostic equipment. In terms of what the sum difference is to any human, it is totally utterly undetectable. PS makes its money from gullible people with little or no scientific/electronic knowledge,who have lots of money to spare. [I am from an electronics engineering background]

This guy uses these videos to promote his business and components that’s why he is in front of his product every time,some good information,but it’s he’s real agenda,don’t be fooled

Boy, oh boy! Just mention your going to sell something that cost $20,000 to 30,000 and listen to them cry foul! Can't afford it? Improve yourself....and then get a better paying job or stop your crying!
