Alpha Labs - Measuring a Power Supply Mod - Sbooster on NODE!

- We have the Sbooster power supply modification for the NODE N130 in our labs. We are going to show you how we measure it to check out the differences in performance. How is the Sbooster better? Is it better? And how? Check it out in this video!

Very interesting. Thanks Jaap,, 👍🌟👍
fantastic and answered a question I had on the sbooster!!!
Great video! Would love to see the team spend a Sunday taking us through what a good basic entry system sounds like and then gradually introduce changes like better speakers or amplifier then wires etc until you end up with reference sound. Given your access to equipment and space I would think you could demonstrate quite easily the scale of improvements as the hobbyist moves from good entry level stuff to reference gear with all the tweaks. Thanks!
Good idea!
i was expecting s booster to make more of an impact, great work thanks for sharing
Welcome! We mostly measured noise now. But there is a difference in speed, control, etc as well. But we can't measure that... yet.
@@oguzoz3008 There is a difference in how fast a power supply can deliver the current. That's the speed I am talking about. Control is how steady it can deliver the current.
@@TheAlphaAudio I just paid for mine today(with upgrade) so I am praying your tests show a massive improvement. As so far they did look similar to the untrained eye. or was that just due to the vertical scale?
verry interesting.👍
It would be very interesting to see a blind listening test to see if the participants could identify the modified power supply.
It is pretty obvious.... Really. We will make a sample video.
@@TheAlphaAudio that would be great.
Thank you for these videos and hope to see more blind tests.
Have you done benchmark tests on power supply impact on wifi and cable modem routers? I am wanting to change the cheap DC SMPS on my internet devices, but not sure if something like an sBooster is really going to impact the audio equipment at all (DAC and streaming devices are wifi for now) THANKS!!! Great work as always and very appreciated!!
It does have impact. Measurable and audible. Pick the right power supply though. It needs to be fast.
@@TheAlphaAudio it seems from your testing that is very true! I'll be experimenting with a couple different power supplies and using a 'noise sniffer'. Thank you for doing some great work!
nice, although, must you not have a input and output connected and then measure the noise at the output (analog) ?
We did. The analog output is not connected when we measure network and psu noise.
What about the digital output. What difference does the external power supply have when using the node as a transport?
Mostly the same. But jitter on the digital output is honestly pretty high with the NODE.
Noise affects equally using Node as streamer only than streamer+DAC?
Yes
How clean is the power coming right from the sbooster? Are there better LPS?
What do you mean? Noise output on de DC output?
@@TheAlphaAudio yes
@@Pete.across.the.street I have to check that and compare apples to apples. We have a new setup. And you cannot compare the old with the new one.
Great video 😊 I use a pair of Sboosters. Would be interesting to see how a Plixir elite edc measures. Keep up the good work 👍
Are those "grass" at -100dBu levels?? Thats like 0.000001 Volt RMS. That's "definitely audible"??? 🤣
And that gets amplified...
@@TheAlphaAudio Ok, so, where are the measurements of that noise getting amplified?
