Hi Guys,

I thought I would start a separate topic for this where you can post feedback, wish list, preferred voltage options etc.

 

Regards

Clay.

Hi Clay, I fnally got around to setting up my Intel NUC. It is Windows 10 and is running Jriver and has a 250GB SSD.

I am flat out hearing any difference between the NUC and my laptop running thorugh the DAC at this stage.

 

How much and what sort of difference will one of your power supplies make?

 

Cheers,

Steve

Mine just showed up, looking forward to trying it out tonight! Thanks Clay!

I'm very happy with my 5VDC Gieseler Power Supply.

It's very well made (as per the Klein DAC) and sensibly designed. Quality Neutrik connectors, robust switchgear, and the same heavy high-quality EI core AC to AC external power supply (a very smart idea IMHO!)

I also ordered a set of spare black faceplates for both the Klein DAC and PSU, should I decide to go 'all black' in future to match my Sansui gear. For the time being, I'm very much in love with the silver which provides a nice contrast to the blackness elsewhere in my rig.

This unit is configured for 5VDC and powers my Squeezebox Touch. The old switchmode PSU is banished, and my system is finally switchmode-free!! Huzzah!!

My listening impressions are that there is a slightly lower noise floor (dare I say it... blacker blacks? ha!) with greater clarity. It's not an earth-shattering, night-and-day, but enough that I'd be comfortable picking it in a blind test (if I was that way inclined!). I'm very, very satisfied with the improvement in refinement. I think it's a very worthwhile improvement for the Squeezebox Touch at this price point, and I'd wager that the benefit for other types of digital and analogue gear (and mini computers etc) would be similar. Best of all... it's Australian-made and designed :)

Well played Clay! I'm one very happy customer.

Hope this isn't a dumb question, but does it makes sense ordering the 3 output unit for current/future use, eg. Regen, Auralic Mini, etc., or does it somehow detract from the SQ benefits if powering 3 items from the one Power Supply (rather than 3 separate power supplies, single unit better bang for buck, but also space saver - less boxes).

Hi Steve - running the NUC from a low noise linear supply should definitely be an improvement vs using the std SMPS plugpack it comes with. Generally I find the linear supply removes a a layer of background grunge & improves resolution. Pete summed it up well, better blacks.

Just how much difference you hear would depend on your system, how is the top end on those mighty three way horns of yours now. Has Henry fully sorted the crossovers yet?

John - my triple power supply has very good separation between the three outputs but they do obviously share the raw DC source voltage. There may be a small improvement with three fully independent supplies.

You're not alone- I don't hear much of a difference between my RasPi, NUC or laptop with USB audio. Sometimes I think I've noticed something, but I don't trust my brain. I've been having problems with USB audio sources for a while and I've sorted it now. It was all in the power. The sound from both my laptop and Brix (NUC) were noisy, which ruins the highs, and the obvious: noise! I did away with the nasty switchmode plug packs. The difference is night and day. It's not subtle. It's obvious. I notice a major improvement immediately in the noise floor, which cleans everything up. It's really nice not to have that faint CPU cycle buzzing too. No matter what DAC/Amp/digital source I used, I could always hear the power supply noise which ruins everything. Got rid of those plug packs, and problem solved. Clean DC power put the final polish on my system- maybe you'll have a similar experience to me.

Clay, yes 3 seperate supplies may give a small improvement, but then having 3 boxes, 3 transformer blocks & 3 more cords to plug in seems more hassle unless someone is trying to squeeze out the last ounce of SQ from their system
