The £25,000 Pre-Amp Repair and the Copyright Strike

Mark did a repair of £25,000 Phono Pre-Amp in his last video. But the video got taken down by the manufacturer! You can learn about the story in this breif video synopsis. Obviously, Mark has been very careful to not infringe on any of their "copyright" in this video. Fair use, fair use.... Oh, and here's to our Right to Repair!

With your permission, I would like to re-upload your original video to my channel. Then, if a fraudulent copyright claim is filed on my channel, I will fight it to the fullest extent of the law, to the point that a lesson is learned to never do this again. You do good work, sir, I respect your work, and I want to help send a message to companies that do this kind of abuse that it doesn't work.

[@alixxworkshop846]

After seeing Rosmann's video and reupload on NickT6630's channel I have to say something. At first BIG respect to you, Sir Mark for doing this repair,reverse engineering It and showing the people about this how do I call It-scam. I mean 25.000 pounds for some garage made science project worth 100eur in material? Plaastic circuit board holders and so badly designed?Not to mention copper "covers" with the holes made by some kid,and "PLASTIC" screws holding cooling for the transistors? NO COMMENT. Come on this is a big shame for our technical field. I as engineer was feeling bad and ashamed what I've seen inside of that "premium" ovepriced junk. I have no words for It. I've seen a lot of bad stuff but this, with that price tag is probably worst I will ever see in my lifetime. Thank you for your video It was really educating and usefull. God bless you Sir!

[@freyalewis2460]

You might be able to fast talk me into believing cheap electronics can make audiophile grade hardware. Like if what you were paying for was extreme parts binning for low noise, that would be fine. But for $25k you can build a much better enclosure without cutting into your profit margin too much. There are hobbyists doing much better work just in terms of fit and finish. This is pretty embarrassing and that's probably what the manufacturer is trying to hide.

[@SharienGaming]

@@freyalewis2460 yeah i think you can get some pretty good audio with cheap components and assmebly like this... but none of that justifies the pricetag at that price, i would expect the thing to be a fraction of the size with an integrated powersupply and a lifetime warranty (mine, not the devices)... and even then that still feels like a stretch... like none of the principles inside of that thing require crazy levels of expertise or skill in assembly... it requires some sure... but im betting if i ask around among the second year university students for engineering faculties, someone could build something like this

[@bigclivedotcom]

Congratulations on reaching 100K. The copyright and flagging system on KZbin is very random, and often false flags. Every one of my strikes has been completely nonsensical. I really thought they'd tell you the specific thing that caused the strike though, whether it was music or artwork. Although my recent strikes had no information about the cause and I couldn't get that answer from KZbin. It wouldn't surprise me if entire technical channels get deleted in the future because we probe about in live electrical equipment and it's deemed dangerous.

I just might be able to get a remote job with Floatplane. I already get my music somewhere else and run a home server to access it anywhere with internet. I can add music remotely, download to my device, give friends access, etc. You might be surprised how much music, videos, and lyrics you can stuff on a 500GB M.2 drive. YT is going to lose their monopoly if they don't stop pushing good creators to other platforms. Twitch is in trouble, too. It seems that these companies couldn't make an intelligent move to save their own butts. It's all just shady, dodgy, underhanded BS. Anything to drive profits, as long as it's not honest or ethical.

Unfortunately for Tom Evans, I am speechless. I don't know him and, frankly, I don't want to. What I saw was a terrible product, assembled in an amateurish way, a disgrace to electronics. 25K euros? What a shame. I wouldn't spend 25 euros... Mr. Tom, please grow up.

Now I have to add; I had never heard of Mark or this channel. I watch many electronics repair channels, or I did until I found this, thanks to LR. I have been binging on Mark's back catalogue, and now have to pace myself so I don't run out. It has been an interesting journey, watching Mark's past three or so years condensed down to a month. What's astonishing is how little he has changed as his subs grow. I notice mainly a growth in his confidence, not in his abilities which speak for themselves, but with his audience. We now see a little more of Mark, when he subtly jokes with us, but the core is a bloke who is totally passionate about what he does and is simply delighted to share it with us. I don't watch Mark because he is a master technician ( he clearly is ), as there are plenty of them all over YT, along with many who are not. I watch him as he humbly takes us on the journey, admitting his mistakes, acknowledging his rare failures, and just being a decent, honest bloke who you might meet at a pub with a dart in his hand. I dunno if Mark goes to pubs at all, I am just saying he is an unassuming genius who deserves far more subs than the pretentious people who actually get them.

Because it's not a bunch of shoddy looking PCBs held together in a tower with plastic standoffs, and it's coming from a major audio electronics manufacturer with decades of experience and legitimacy behind them. This is where people get mixed up. Being expensive doesn't make something audiophile garbage. It just makes it a high end product. The garbage kicks in when you start making claims that are either easily refuted through double blind testing, a basic usage of metrology equipment, or the usage of your own eyes.

The problem is they usually fail short, and take out other components, instead of failing open.

Hello and greetings from Germany from an electronics engineer who also learnt his trade at a university over 35 years ago. You show in an entertaining way how in the past, as well as today, very expensive snake oil was produced and sold in the audio sector. Tom Evans' reaction indicates that he is obviously now realising that he has also produced a little snake oil or, as you have seen and shown, he has simply recognised very well how to create an expensive product using standard circuit designs, some of which are taken from manufacturers' operation manuals. However, I think it's very dubious to strike back via copyrights now and I believe that this action will be pretty bad for him for marketing reasons. So keep up the good work of repairing beautiful old and expensive things. Best regards, Jens

I watched the origin vid (I watch all of Mark's videos). The wood mock up with the the tant caps dumped on it had me LMAO. So funny for those of us that saw the home built, first pre-amp project design/quality of the actual device. Good on ya, Mark!

[@StealthParrot]

I saw your video posted by another user and found it fascinating for a number of reasons. First of all, I learned several great tricks I hadn't seen before such as plugging in the shorted device board and watching the overheating component using a flir camera, heating a screwdriver to melt a slot into the broken screw in the standoff, repairing the broken cover, and some great soldering techniques. I found your whole approach to troubleshooting exceptionally efficient and well explained. As for the copyright strike, I truly don't get this at all. With 124,000 subscribers (+1 more) essentially you are exposing this product to a huge number of people who otherwise would never have heard of this manufacturer. Clearly these are being hand built judging by the workmanship, so what is the point ... are they ashamed of their work, the price, the right to repair? Watching the video, honestly I was mostly captivated by the troubleshooting and repair than the actual product. It could have been any electronics equipment really. Chances are this manufacturer does not have deep pockets, it's not like they are Sony or something, so I wouldn't get to concerned about it all. Glad to be a new subscriber.

[@kirkhamandy]

Pockets not as deep as Sony maybe, but the serial number was 58, so up to the time that unit was sold, he'd earned 58 * £25,000 as a cool £1.45 million. So deeper pockets than me, that's for sure.

[@StealthParrot]

@@kirkhamandy No, there is no way he is making 100% profit on each sale, that's just not realistic. 100% markup maybe but definitely not profit. You have material, labour, overhead, dealer costs. My point really was more to do with the irony of why a small manufacturer would basically thumb their nose at the exposure to a large group of people who otherwise have likely never heard of them. I would be very surprised if they go beyond a cease and desist letter, if that.

[@kirkhamandy]

The thing is, the preamp did do what it claimed to do - amplify the very weak signal from a moving coil stylus, without introducing extra noise and maintaining clarity and extension into the frequency extremes. Whether it did it better than less expensive moving coil preamps is open for debate

[@derkeksinator17]

@@thomasstone1363 it does better, that's out of the question. I wouldn't even have an issue with them selling it for that price, if the physical construction and layout had me drooling.

[@hansjanssen3364]

Why? The Lithos power supply boards are what makes the unit special. These are Tom Evans-copyrighted designs, and from my recollection of the video, Mark took measures to protect those designs. He discussed the reverse engineered schema's for the main amplification sections, which in itself is not a copyright violation. Also, as I said elsewhere, you grossly underestimate the economics of small series production and mark-ups in the chain. The 25k is a retail price. Dealers take a hefty chunk of that. If this is truly hand-built (and there is no evidence to suggest it isn't) then another significant chunk of that money goes to components and time spent. Apparently that, the time and effort to build a brand, perform marketing activities etc. are things a manufacturer is not allowed to be compensated for, in your opinion.
