    The best improvement in audio business! Every owner of BS must be informed of this great products. I bought complete set with linear PS and the sound is pure analog! Thanks a lot, Pawel!

    This kit (with the big low noise PSU) was purchased to upgrade a BS Node 2i : fantastic result either using an external DAC with the BS (throug SPDIF out) or using the internal DAC (RCA out).

    Honestly I had already an interesting upgrade with the use of a Denafrips Ares II as an external DAC with the BSNode BUT using the BS Node with its internal DAC and this external PSU is already impressive and almost on par with using the Ares II !!! Which means a day and night improvement and the best bang for your buck option out there !

    This external PSU kit alone already brings better clarity, especially in the bass domain and the treble, becoming more defined – the result is a wider soundstage and better instrument separation with a more subtle resolution overall – I would say it brings at least 50% improvement in sound quality (don’t quote me on this, you can’t measure it, it’s subjective)

    When you combine both this external PSU and a very good external DAC (the internal DAC is already good in fact) it sounds absolutely fantastic and you completely rediscover your amplifier and speakers. I would say that there is no point to use a better DAC with the BSNode before you have already upgraded the power supply: The qualities of the Ares II in my case were only really revealed after the power supply upgrade on the BSN.

    And for the ones that would be afraid to open their BS and install the power board inside: it’s rather easy and it’s hard to break or damage anything – the operation is really safe.

    Great upgrade for the Bluesound Node 2i.
    Yesterday, after installing the interface with the included instructions and preheating the PSU, I had a little scare due to an error of mine that I quickly noticed and solved, and the music started playing.
    After several hours listening yesterday and today since the beginning of this morning, I have to say that an improvement in the sound is already noticeable (more clarity and better dynamics). Really eager to do the full running-in shooting.
    The delivery was fast and the product arrived perfectly packaged. Excellent communication with PD and his attention was unbeatable. Really satisfied with this purchase.

    Great improvement. I was not expecting such a fantastic result. The node2i is connected to a NAD C390DD DirectDigital DAC Amlifier which was analytical a bit grey, not too lively, in character until now when used with the standard node2i. Before the PSU upgrade, I could not hear a difference between SPDIF and AUDIO OUT RCA feeding de single-ended input card in the NAD C390DD. Now with the PSU upgrade, comparing SPDIF vs AUDIO OUT provides a very very significant improvement. SPDIF feeds the NAD built-in DAC though, and the AUDIO OUT RCA is converted again to digital for the NAD. And well, the digital-analog-digital does not degrade the signal. Quite the opposite, the sound is clearer, basses are tight and much more dynamic but also lacking any rumble and sort of resonnances that so far I was attributing to my room characteristic, but it is obviously not. On B&W 804D3 speakers, high and mediums are so natural and liquid with crystalline positioning and voices with good recordings are reaching out to the listener with deep emotional impact. Besides changing speakers from bookshelf to the B&W’s, I think this is the best upgrade I ever made in my system.

    Excellent upgrade for Bluesound Node 2 !
    I installed it on Node 2. If you follow precisely the instruction guide, it’s quite easy. As shown in the assembly guide, long nose pliers are required to disconnect the connectors. Finding the good pliers was the most difficult.
    After assembly, I immediately tested it and I was disappointed with the sound !
    I decided to let it burn in during the day playing music and came back in the evening, 8 hours later.
    I didn’t recognize my Node 2, the sound was better everywhere, Wonderful !
    The sound was simultaneously softer with more richness and an easy dynamic. The soundstage was easily perceivable. I could listen to music louder without any fatigue. I had the feeling to attend directly to the recording session.
    I didn’t heard until now such richness of these music files (44,1 kHz / 16 bits). Until now my best digital source was my high-end CD player connected to the DAC but after this upgrade the Node 2 took the lead !
    So I decided to listen some transfers from LP to wav files (44/16 and 96/24). Until now I was always disappointed with these files because the transfers sounded poor in direct comparison with LP. This test was the definitive proof of the progress of the upgraded Node 2 , I was able to get back the original softness and the richness of the LP. It’s now a pleasure to rediscover these recordings immediately accessible on the SSD.

    Equipment for test:
    – Node2 + PD Creative Upgrade Kit + Ultra low noise PSU. Node was connected by Coax SPDIF to DAC.
    – SSD connected through USB to Node 2 and loaded with wav files extracted from CD or bought from Qobuz (192/24) and transfers from LP (44/16 and 96/24)
    – DAC and headphone amplifier Fostex HPA8C upgraded with Burson and Sparko AOP
    – Headphone MEZE Empyrean
    – Accuphase Integrated
    – Focal Electra Loudspeakers + Velodyne subwoofer
    – Neotech UP OCC Cables everywhere
    – iFi AC Purifier
