Having recently purchased a JDS Labs Atom and Topping D50s (still on back-order) (thanks Amir for the reviews!), I have been looking for a way of adding network streaming capability to access music on my file server. Ideally this would be a simple and cost effective solution which can run software such as JRiver, Volumio etc.
Immediately, the best bang for buck solution appears to be a Raspberry Pi. After some research, mainly on this forum, it appears that there MAY be some considerations regarding the source of power when it comes to these types of "USB transport" devices. Referencing the following links:
1. https://www.audiosciencereview.com/...d-review-of-sotm-sms-200-network-player.1846/
2. https://www.audiosciencereview.com/...ts-of-sonore-microrendu-v1-4.1867/#post-48479
3. https://www.audiosciencereview.com/...o-you-need-linear-power-supply-for-dacs.7021/
The general conclusion seems to be:
1. Any noise introduced by the power supply to the USB transport, will have no audible result on the output of the DAC, though measurable.
2. To reduce noise, use a high quality linear power supply.
3. For the DAC, linear power supplies yield no performance benefit.
This all appears to be a logical outcome considering the focus of this being in the digital domain and also the superior filtering implemented into today's circuit designs and IC's. However, there appears to be some very cost effective solutions to eliminate the noise, and I would love to get opinions of these ideas/options:
1. Allo USBridge/USBridge Signature (soon to be released) https://allo.com/sparky/usbridge.html. I cannot find a detailed review/analysis to verify their claims.
2. Battery powered Raspberry Pi by one of those inexpensive USB LiPo power banks. This would be a very clean source of power, if I am not mistaken. However the RPi may generate some noise of its own, rendering the battery useless?
3. You wont hear a difference and are overthinking it, just get a Raspberry Pi, Windows tablet or Pipo device, with USB port. http://www.pipo.com/productlistal.php?cid=43
Would love to know your thoughts. Thanks.
