Node 2i

This is a very good upgrade!! I had no high hopes for a big improvments, but was I wrong… The sound is so much better. Base is much tighter and deeper. Sound image is bigger and focus is so tight. Vocals are sitting exacly infront of you. This is an upgrade all with Node 2i should do!

C3 MkII N130 Clock DIY Upgrade

C3 MkII clock board was installed in my Node N130 by local audio repair shop technician following the excellent instructions sent by Brent. Together with it EMI/RFI treamtment was applied as well. The result -everything worked great fom the start. What is the difference in sound after couple of months usage for break-in, having in mind I also have PD Creative linear power supply unit and filtering board installed before clock upgrade - the sound became clearer, as if fog is lifted and I am finally enjoying it without thinking for equipment using the analogue RCA output to Edifier S3000 pro active speakers. Compared to power supply upgrade to linear, which was night and day difference in my use case, clock upgrade effect is more subtle, but worthy as it brought that final piece of the puzzle that you may not know is missing back to the music. Now I can just listen and have fun without tinkering anymore.

Summary: Very happy with upgrade, RCA analogue output has become clearer and better defined, hdmi and optical inputs sound a way better and digital outputs like usb and coaxial have also great improvement. If you have better external dac may be that is where you will notice biggest impact of clock upgrade. I however do not and cannot elaborate on it further. Once more, thank you Brent for the excellent experience, communication, support and timely replies to my questions. Such a proficiency and engagement is rare these days.

Excellent value for money and service! Verified Purchase

It's not easy sending off part of the system for an unknown upgrade with very little by way of feedback from others, but I am very happy with the upgrade, and equally the quality of service I received from Brent. Well worth the money, many thanks!

Top notch Verified Purchase

I have now installed in the node X the C3 MK2 Low Jitter Clock , EMI / RFI Treatment and the Signature V2 Low Noise PSU + Reference Interface of fidelity audio.

(I played with the Sbooster and the aib for this, before that with that of pd creative)

But wow what an update this is, really bizarre what comes out of this little box really fantastic. Makes the node 3x as expensive with all the highest tiers (psu and interface)🫰😅, but totally worth it

C3 MK2 transformation

"My goodness the C3 MK2 upgrade is amazing. As many a review will tell you, there was a night and day difference in the sound from the Node N130 after the PSU upgrade, but actually the day was somewhat hazy nonetheless - until the installation of the C3 MK2 Low Jitter Clock cleared up the weather for a glorious day with sunshine from a cloudless sky.

Moving away from imagery, it's almost eerie how the presence of C3 MK2 provides another significant upgrade to Node's performance, and I can vouch that the expectations listed are all met.

Previously hidden nuances are revealed, making voices sound much more articulate, and what's truly amazing is that while the sound is initially perceived as more fluid, it also delivers increased stereo stability in a more spacious sound stage that has gained amazing depth: A whole new level of realism. My highest recommendation."
