Hey folks, I just posted a review of Clay's Kraftwerk II this morning as part of a broader look at the potential benefits of linear power supplies. I hope it's helpful:

 

 

And, to put my money where my mouth is, Clay has just shipped me my third Kraftwerk II that I've purchased. The two in the review are in regular use in my system so this third one will be used for testing any devices I review that have 5-12V DC input.

Shame your link was removed. I was just going to have a listen.

It worked for me?  

[Gieseler Audio]

Perfect for me too!

It now works for me as well - very strange on my iphone it was replaced by an advertising link.

Have mentioned earlier that the Dual Kraftwerk II has been powering my Intel NUC and JCAT USB XE card. It is an integral part of my Kii Three setup delivering the sound I have been striving for.  Here is what the setup looks like:

Just added a Dual Kraftwork II to my SOtM Streamer and USBRegen. I thought the streamer was great beforehand but this has taken things to another level. I know that sounds like a bit of a cliche... I was expecting a subtle uplift, but what I received was more than that. The bottom end is rock solid, vocals more pronounced, better imaging and an uptick all round in separation and fidelity. It’s made the SOtM basically better in every way.

 

I was a little bit apprehensive that the benefits of going to an LPS would be marginal and there might be better ways of spending the money but OMG, this is much more impact than I was expecting. Especially the increased coherence in the bottom end. And the vocals. They are more forward, and natural sounding.

 

Very, very satisfying! Very happy customer.

Just upgraded both of my Kraftwerk II Dual LPS power supplies with 4 of the Gieseler Audio Canare 46S Star Quad DC power cables.

 

It was a win .

 

TL:DR;

- improved my enjoyment of music

- inexpensive tweak which improved/leveraged the benefits of my Kraftwerk II DuaI LPS

- provided noticeable results

 

My only regret is that I wish I did this earlier.

Cost was $65 each [have spent much more for less results trying other upgrades].

Clay customer service was as always - outstanding.

 

Anyhoo, got the opportunity to do a comparison of:

Gieseler Audio Canare 46S Star Quad DC power cable

VS

Stock DC cables that arrived with the Kraftwerk II.

 

Previously I already had 2 of the upgraded Gieseler Audio Canare 46S star quad DC power cables for both of my Gieseler Kraftwerk II LPS that power my each of my EtherREGENS that are located on my AV rack.

 

With both of the Gieseler Kraftwerk II Dual LPS - that are located on my network rack - I was just using stock DC cable. With my adventures in optimising my network to improve sound quality quieting down, been thinking of finally getting Clays upgraded DC cables for the Kraftwerk Dual II LPS now that I know what length and DC plug were required.

 

For context my headphone audio + network path* is:

NBN FTTP -> Firewalla Gold -> MikroTik CRS305 -> MikroTik CRS305 -> MikroTik CRS305 -> EtherREGEN -> Naim Audio Uniti Atom Headphone Edition -> Focal Utopia 2022 Headphones.

* I find running three MikrotTik CRS305 10G switches daisy chained with Cisco Active Optical Cables [AOC], then Finisar SFPs FTLF1318P3BTL for the final single mode fibre optical connection to EtherREGEN to currently be the best for SQ. Router and all switches power by two Gieseler Kraftwerk II and two Kraftwerk II Dual LPS.

 

Following is what I noticed [in the order that I noticed the SQ attributes]:

Detail: Initially thought I had accidentally moved the volume button up as I was hearing more detail, crisp, on one song noticed whispers between musicians prior to the start of the song [never noticed that previously, maybe I am just hearing more low level detail]. Sometimes more detail can be from boosted high frequencies though not in this case - the frequency range bass/mids/highs were still in balance. Not sure why this is, maybe lower noise floor [?].

Clarity: More clarity, less congestion.

Bloom: More expansive, richness.

Soundstaging: More width, height, depth.

Imaging: More focussed, instruments in their own defined space.

PRaT: Especially pace and rhythm, especially for rock.

Poor recordings: Still sound poor or just OK.

Good recordings: Sound better.

Great recordings: Sound better.

 

For perspective sometimes I make a change and it results in either:

- SQ degrades

- No improvement

- One step forward, one step back

- Marginal positive improvement

- Noticeable positive improvement

 

Noticeable positive improvement was what I found with upgrading to the Gieseler Audio Canare 46S star quad DC power cables.

Thanks for the heads up. I didn’t realise that Clay was making cables.
