I did the same with NAD C399 and the bass is now very tight and precise, mids are doing deeper soundstage and high's are more stable....low volume listening became more fun....sad that company's are using this cheap type of connection😢
I doubt this mod. Solder is one of the worst conductors so you may actually reduce the conductivity by soldering the wires. Often a crimp connector is a better way to achieve a good connection, or the combination of crimping and soldering.
Hello! I am late, but I just found this video, which has encouraged me to subscribe. You are definitely on the right track here. However, I'm not entirely convinced that soldering is absolutely necessary for 'all' those connections. Perhaps, yes, but I would need to have a closer look for myself. What is important is to eliminate the plastic connection boxes, which are introducing bad dielectric points throughout the wiring. Also, it is good that you prioritize the power supply and outputs, which makes the most difference in performance. You are also correct to use copper connections, and single strand wire with silver solder. However, I believe you may get further improvement by using a smaller gauge of wire. Something around 18AWG, perhaps. Not smaller than that, though. There are still more things you can do with this that will bring the sound to another level. I am considering one of these amps for my system, and would make radical modifications to it. Where you have ended would be just the beginning for me. It is very good to find someone else who knows some of these "secrets" to achieving the full performance potential of these products, which are capable of going far beyond the sound quality of the stock product if one knows how to bring it out of them. Please keep up these kind of informative videos, as more people need to be aware of the possibility of greater performance without having to constantly buy new gear, and the sense of accomplishment that DIY can bring. Bravo!
Hi, thank you. Unfortunately, the mechanical solution with different circuit boards per channel is poorly solved here. I only use solid core OFC wires. I'm talking about resonances/resonance chains. Unfortunately, most manufacturers don't understand this, or just want to woo customers with better and better measured values. One of the few exceptions is Soulnote. Best regards, Mike
@@headquarteraudio5388 Tag, Mike. Thank you for the kind reply. Yes, I am familiar with resonances and vibration control. I believe it could be reduced in this case by removing the boards from the unit, then using brass stand-offs with M3 size brass acorn nuts as feet, mounted to a thick softwood board and carefully weighted. This creates an effect where vibration is drained into the wood base and dissipated or absorbed there. It also eliminates the box, which is one of the greatest sources of resonance. I would be interested to know what you think of this method, and if you can provide more information about what you know of resonance chains. I am always looking for more reliable information on these subjects. Cheers, HdL
Appreciate the tips - excited to implement on mine. Beautiful listening setup. Probably a silly question but I have to ask; is that cymbal placed there with intent or just a storage location?
Hi, these are my Open Baffle Qunique RS developed by me. Yes, but 10 years ago.. if you have neutral Cable built right and a neutral rig, you dont need these stuff.. my opinion... 😉 cheers Mike
Wow😮 The sharp sibilanse is gone....it is the one thing that anoys me about mine... I do not dare to try and modify mine though, I'll probably do something wrong🤪
cause its cheaper and if you run a production factory and workers there need to solder things then by the law you need to have a special ventilation system and thats very expensive and its also checked by health inspection every few months...so thats why they just using this cheap shit....and thats also in some high end brands
Same solution for A400s? Looking forward to get an XTZ because of the size and convenience, my only fear is hiss at low volumes?, did you experienced that? Almost 10 years I don't hear a class D amp
Hi, my Krell ( tuned ) is much better specially in mid and highs. But in Bass the XTZ is a monster :) I dont like devices ( the XTZ ), built with different boards with different size for each channel.... cheers MIke
@@headquarteraudio5388 Thank's... Just wondering...because I have updated my HiFi system. I found a pair of BC Acoustique ACT 3, second hand. When I listened to them in shop they paired them with an Yamaha s1200....they sounded very well so I bought them. Then I bought a Yamaha wxc-50 and the a2-300... I set it up at home and listened to them, my set up was by far much more dynamic compared to the Yamaha...big difference... I'm happy...but I might solder the interior... And upgrading with one more unit will take care of the asymmetry in the amp...✌
Hi, I don't know in which damp basement you're listening with your measuring devices, but up here with a real system or with headphones without stuffy ears, the difference is huge. By the way, the loudspeakers were developed by me without measuring devices... (only checked at the end) Cheers Mike
@@headquarteraudio5388 My ears measurement tell me, the voice is now melting better with the low-end, but still a bit sterile in the top-end which is probably the limited resolution of class D?
@@booom4849 Hi, class d is not digital. Resolution is not limited, the class d module is a cheap one. There is much more expense necessary than in this amp to give you a real good top end. LPS is most important... cheers MIke
Lots of snakeoil here. Soldering (btw, your soldering skills is rubbish).If you going to solder remove the contact completely and solder the cables directly on the board You dont have basic electrical knowledge. Solderings is by far worse to get electrical contact then using crimps or screw connections.........
![If you can't hear this then you're not an audiophile [See description for link to followup video]](http://i.ytimg.com/vi/48PxwspDvrE/mqdefault.jpg)
I definitely can hear the difference through headphones. Great bass from your lovely open-baffle speakers :)
Thanks! :) cheers Mike
Amazing how much audible improvements !!!!
Hi, yes , i was surprised too..cheers Mike😀
Love your videos!!! Keep em comin.
Thank you, more soon...cheers Mike

In my ears...big difference...close to your Krell...👍

Hi, with intend 😀Cheers MIke
Waouw ! Impressive, really, what a change ! Well done Mike . Congrats !
Hi, yes. I almost fell off my chair :) Cheers Mike
Congratulations, this sounds amazing!!! Which preamp are you using?
Hi, i use Denafrips Athena tuned by HQA. In origianl shape also a wonderful piece for the price...thanks for comment and cheers MIke
two questions: which speakers are we listening? second, have you try to use a ferite for the power supply cables?

Hi search for used class D Pink Faun 180er monos...cheers Mike
hi... do u know why they connect the speaker wire like this . and not just solder to the speaker terminal. is it a sonic filter.. ?

Night ans day. Bravo
Its not to believe how much the difference in real is, specially one day later....many thanks cheers Mike
Очень хорошая сцена звука. 👍5 баллов.
Привет, если вы ищете звуковую сцену, тогда послушайте мое последнее видео в наушниках... Аккорд Дейв удивительно реалистичен... ура Майк
Would you do ot to mine for me i have two coming soon in uk im never gito be capable of doing it myself
soooooorrrry no...

No difference. Unless you can measure it, it's placebo.
