- In this video I am visiting inakustik the manufacturer of HiFi cables at all levels, power products and music production and re-distribution. They are based in a stunning area in South Germany.
I am visiting them for a second time to learn about AC power quality and how it can affect the sound quality of a HiFi system. Part of this is the theory behind the problem. The second part is learning about the inakustik power products that help solve these problems.
Huge thank you to inakustik for allowing me to visit them again

Thanks for watching the video, please remember this is a complete one man production in terms of the video and audio work. My intention was to feature more in the video myself, however I forgot two very important microphone adaptors so only had one working microphone so had to shoot the video with only ever one person speaking. Thanks all the best
I was too absorbed in the video to notice, until I saw your message.
Great work Terry! You always go above and beyond. Cheers!
Super cool Terry, I love these behind the scenes HI-FI video on how things are made. Always something to learn! Thank you!
Thanks Terry great factory visit to Inakustik, enjoyed the video.
Thanks Russell
I’m sold!! I want one for every piece of quality electronics we own! 🎉
What an incredibly clean working environment. Very impressive. Well done review.
Excellent video Terry, this taught me a lot I didn’t know.
Thanks Terry! Very interesting info, and presented with more detail than I've seen elsewhere. Keep up the great work!
That’s amazingly kind of you mate thank you very much
Perfect video Terry , thank you
Thanks very much for the kind comment :)
Great video Terry its always interesting to see behind the sceens of a high quality audio company and very interesting to see their designs and why they have chosen a particular path to lead them to very well engineered products, more please.
Thank you Matthew
Outstanding video, Terry.
Thanks Eric
Great video very interesting and informative 👌thanks 👌
Just upgraded my PrimaLuna EVO300 integrated amp with a better quality power cable (unfortunately another brand as I have only just come across Inakustik) and the difference was amazing. Mind blown! More clarity, definition & resolution. More spaciousness. More musical details. Thought this may have been snake oil but am now completely sold on improving your power source for significant improvements in music quality. Timely and excellent video on an important and often overlooked subject in our HiFi systems. Will now be looking more closely at the Inakustik solutions however they are not inexpensive but can see from your video the quality and engineering that goes into each product. Good German engineering just like my Porsche 928 :-) Thanks
I have always used silver cables since they became available and for my ears there is nothing better.
Thank you for your time and effort. The next time I'm in Germany I think I'll look them up.
Cheers
Gold is even better
Why didn't they show the measurements with the power station that eliminated DC offsets?
the same reason why they don't use 'power stations' w/ their high precision fq generators or oscilloscopes :)
Great work,I,d love to see a video showing you test home batteries to power hifi,Eg bluetti or eco flow,Anker there are many brands.
Interesting as always, the channel is "pursuit perfect system". As an aside, I would welcome you revisit the perfect system options in relation to budget and the impact of diminishing returns taking into account I always respect your comment its always down to personal listening pleasure. Also how's the vinyl journey?
Great video Terry. You have a lot to answer for. In my case it was IsoTek - a couple of years ago(?) your vids caused me to invest in a Mosaic Genesis... Seems pricey - until you hear the results. Your recent work has been world class ;¬D Greetings to you and yours
Thanks very much Anthony and yeah the Mosaic is the one I always wanted :)
I've been contemplating buying an active grounding device made by Telos. Seeing all those 11 volts coming off one of the ground RCA out terminal of a CD player (8 mins 35 secs into the video), that was enough for me to "pull the trigger" on getting the Telos GNR. The unit is second-hand to suit my budget (AUD$12K for a brand new GNR) and the dealer is so confident of Telos build quality that I am getting a three year warranty instead of the standard 3 months warranty on second-hand gear.
Part two with cable design and construction would be great any listening tests ? did the DC voltage go when when fitting those filters ?
Hi Paul, this was a part II really, here is part one about the cable designs czcams.com/video/5tFr2JgeaEw/video.html. The test wasnt really showing what would change just that it exists and therefore solutions to make this better make sense, if that makes sense :)
I think part of the reason for the ground difference is the power saving switch mode power supply most hifi components have (in addition to the transformer). Switch mode power supplies are rarely isolated (for some reason).
🙋♂️THANKS TERRY,🤗 FOR HELPING US TO …MAKE SOUND DECISIONS 😁👍💚💚💚
I also wish they showed us the measurements on the cd player and amplifier when connected to filter and purification.
I asked about that, but that wouldn't change the result of the AC being connected to the DC as that is inherent in the power supply. That is a big point of the test its happening all the time
@@PursuitPerfectSystem wasn't this something they told us that this should fix. + Noise. That's way it would be nice if they at least could have shown us... 🙂
No thats not what these products are designed to do, they cant change the products behaviour, they are deigned understanding the problems exist, fix what is possible then alleviate whats not possible to fix with a solution upstream.
@@PursuitPerfectSystem so what he talked about the DC offset that this should fix. Ref. The first module isn't happening with the DC offset on the cd player and amplifier? I'm a bit confused now.
Sorry yes the DC offset gets fixed - that puts the mains in symmetry and not offset but that wasn't what the first test was showing, it was showing AC couples to DC through the primary and secondary parts of the transformer and you cant fix that, but instead they fix the noise upstream so noise doesn't go through the component through the coupling. I am trying my best to explain it :)
Thanks for a great review but where do you get the products shown in the UK.
There is UK distribution through Karma AV so they will be available in UK retailers
Pity we haven't got a clean sinusoidal mains supply as we did 50 years ago before thyristor and triac ac voltage regulation.
Awesome review. Thanks
I'll buy one eventually but 4000 EUR is a bit much for me currently. Any cheaper stop gap solutions out there?
Is this a solution to a problem that doesn’t really exist in real life?
I would loved to have seen real world measurements showing huge improvement on the output side of the audio equipment attached, but alas nothing.
I hope you had a nice trip.
Kindest regards,
Brian
The measurement needs to be what happens to the speaker, because the whole system is connected together not just one individual component. That is what the intro was for explaining that important thing and some of the theory.
Plug it in and see if the speaker sounds different or the same easy :)
@@PursuitPerfectSystem I know, but that’s pretty subjective.
It’s kinda like having a nicely cleaned car and you find that it handles better after the wash (it’s same car).
The aftermarket “tweak” industry still has a ton of work to do to actually show improvements.
I’m not looking for trouble, and I’m truly appreciative of the work you do. 🙏
Take care,
Brian
Yes I agree it would be good if more useful data existed, but useful is just as subjective as listening. I am glad I had shown to me how AC power is connected to DC because some people think its not possible so that was very informative to me.
Clearly snake oil, especially the power cords,, as if the miles of cable to utility don't count, but 3 feet of cable makes a difference
Thats what people always say expect electricity doesn't flow like water and the last 3 feet is also the first 3 feet closest to all your other system cables, but there is a problem with all the other cable too hence the need for a power station - its what the video is all about
Cool! Did you hear a difference with their power distributor plugged in? Better than Puritan Audio Labs 156?
Check out the last 5 minute of the video I explain it all there
@@PursuitPerfectSystem My bad sorry! Just remembered you once interviewed the guys at Puritan and was curious.. Thanks!
The hifi equipment in the video was non grounded AC connectors. Wouldn't the result change if using grounded AC Schuko with all equipment using same ground or even star grounded mains block?
I was wounding the same thing, I don’t know.
17:45 The input side has a third prong......right? 🔈🔉🔊
17:58 That slot board has 3 wired to the socket.... ya, it's running a ground.
I dont think it would make any difference because the test is just showing the AC is connected to DC through capacitive coupling in the power supply. Some people claim AC cant effect DC because they are totally separated but the test shows they are not - super interesting test
Exactly my thoughts Balooba, I don't want to make people to be evil, but im not sure if it wasn't deliberately done.
One of the tests that wasn’t performed was putting the two components (CD & Receiver) onto the inakustic device and then show the measurements. A before and after comparison.
Why wasn’t the same demo/test performed again plugged into their power box?
That wouldn’t have changed anything, the test was just showing there is a voltage on the signal ground because of capacitive coupling in the power supply showing the AC mains is “connected” to the analogue circuit. Nothing will change that it’s part of the design. That’s where the noise lives in the circuit. It was creating real world context for the problem they were explaining.
@@PursuitPerfectSystem Then use an oscilloscope or other device showing the interference and it’s elimination. If the potential remains the same then the interference must be reduced. Otherwise what’s the point?
Before you think I’m not an audiophile and have not spent crazy money or I’m not educated in electronics or electrical goings on, here my “creds” as you kids say: two degrees, electrical engineering and software engineering. 37 years in the industry. MBL 101 speakers, Esoteric, dCS, DS Audio, Spectral and list isn’t done. I’ve spent money in pursuit of realistic music reproduction. Not bad for a kid born into a low income family.
If a device is created that reduces interference, then show it. Those that don’t understand EMI, EMF, capacitance, inductance and resistance don’t believe cables or devices change the resulting sound.
Help out and put end to this and have this company show what there device and power cables actually resolve.
Unfortunately It wouldn't end there as someone would say thats not an audible difference in the measurement according to x, or its not this or not that. This will never end so I don't blame companies for not going down that route for that reason. No amount of "proof" would be enough for some people
Very true, but with proof it may sway some. Not a big deal. Those of us that know benefit greatly. Take care.
Another interesting and informative video Terry but in truth I doubt if more than 1% of your viewership will have the disposable income to spend on products like this, particularly as the whole power issue in hi-fi is such a contentious one. You say you heard an improvement but didn't state it was a night and day one, so back to the law of diminishing returns. Again I say, how many "Average Joe's" out there are in a position to spend thousands on power products and cables for a marginal increase in sound quality ? Fascinating stuff, nevertheless. However, to be fair to yourself, you do cover kit from the affordable to the high end, so for most of us it's either, "Yes, I could go for that", or just merely dream.😊
Thanks Bart, I cant remember exactly what I said but pretty sure I said huge difference, there was a huge difference with the power products in and out - but I didn't want to go into full explanation mode because its not what I created the video for. It was meant for "infotainment" and then people have to discover these things for themselves through their own testing. Not taking anyones word for it, testing it themselves. That is what I believe in very strongly.
To be fair Terry, on rerunning the video you did use the word "massive" initially, when describing the difference between the power products in and out but it kind of tailed off to "improvement" and "better". Audio is such a subjective thing eh and yes I'd need to hear things like this for myself before making a judgement or daring to question your finely tuned hearing. Look forward to your next informative piece.👍
That is exactly it, the difference was massive but preference then comes in like it always does. I think often these things get put into black and white categories and I think it’s broader than that
I wonder if Russ Andrews has watched this ? :-)
What I enjoyed about this is ..watching the voltage change as he touches the chassis or even just moves closer towards or away from the chassis ..
that's proof enough to me that the rack .. risers and cable quality ALL make a voltage stabilization difference. NOTHING at all should be moving around to stabilize the levels.
I`ve looked at your audiocables. While your powercables are done correctly (even if they lacks shielding guys!) you`re far out in the hifi-myths with your speakercables. Your interconnects includes some good idead but fails on others. Again; shielding..
Can you please repeat all the tests with the devices connected to the Inakustik 4500? It is easy to notice that both devices used in the test have a 2-prong plugs, so they are not connected to earth on the schuko end. Can you please repeat the test with devices that have a 3-prong plug, as those are probably 99% of hi-fi devices out there.
I asked about this, being connected to the AC4500 doesnt change the situation where the AC capacitively couples to the DC of the component. But what it does do is bring the differences between the components closer together and reduces the noise on the incoming AC
@@PursuitPerfectSystem Thanks for the answer. I tested Inacoustics products in the past and those are killer products and I don't thinks AC 4500 is any different. Would love to own one one day. I happened to notice in the video that Inacoustics uses MPS Hades plugs on their hi-end cables. Nothing wrong with that as MPS builds one of the best plugs in the world. I just wonder if they get the schuko variant on special order? I am asking because MPS sells those plugs to the general public only in IEC, American and Japanese variants only. I would love to get my hands on a schuko version of MPS Hades as those plugs are killer.
Fancy ground loop isolator?
No end results with the ac4500
Sorry I an not sure what you mean by that or the question you are asking? Thanks
@@PursuitPerfectSystem why they measure before and after on the rca. without the ac4500 they measure voltage but what do you measure with filter
I thought that is what you meant, changing the power wont change the voltage on the RCA that was just demonstrating what they had just explained about how AC power can affect DC power in HiFi
@@PursuitPerfectSystem but not how to avoid this
You cant avoid it, its part of the products design - their products are saying we know this problem exists so they address issues before the problem so it doesn't become a negative to sound quality.
Removing DC from the mains will help and may be noticed first be reduction/elimination of mechanical hum on the transformers.
Filters may or may not be an improvement in sound.
Their equipment and cables appear really well made. People I trust have raved about their power conditioner.
The technical discussion was painful however. Interference on the primary. Sure. Yes capacitive coupling will pass the high frequency on most transformers. Saying the secondary is DC is wrong. Why not explain how a linear power supply actually works rather than an incorrect misleading presentation. Kind of destroyed the credibility of the entire presentation.
They didnt say the secondary was DC, they said the signal becomes DC after the rectifier, the secondary was the secondary coil in the transformer. Its a German guy speaking English as a second language, his English has massively improved since I was there just last year but its still important to take that into account.
I get it, I just wish they didn’t make the cables look all hifi wanky.
That stock cable get chopped off and install iec tail problem solved regarding noise, install shielded cable carbon sheath over tail
Amplifiers should alway go straight to the wall imo experimented with mains strips filters spoil the sound making everything round and smooth
The surge protection only good for your source components and possibly tube amps
Probably best not to over generalise unless you played with every product available on the market. Some are specifically designed for amps so I am sure they are more than fine
If you move the signal off the safety ground using balanced interconnects and transmission none of this is a problem. Because you don't understand the problem in the first place your solution is wrong and expensive.
There is no safety ground with analogue interconnects its just the signal ground - I was wondering how it might look with a balanced connection. Either way the test just shows ac is connected to dc and they are not exclusive to each other.
@@PursuitPerfectSystem Says who ? The shield on an unbalanced cable connects to what in the equipment ? If it doesn't then what problem are you trying to solve ?
This is a good point, I hadn't thought of it like that and will test it myself and see
Would it make sense to block the dc components at source.
