Just wanted to share my set up and recent experience after almost a year of Volumio.
Here is my current system:
- Rasberry Pi4b with Flirc case
- Topping E30 USB Dac
- AudioEngine HD4 Series
- Cambridge Minx 2.1 Subwoofer
- iFi Silent Power 5Volt 2.5amp
- Audioquest usb cables
What I have learned
Volumio Hardware is absolutely fantastic
Rasberry Pi4b is far superior to 3b+ In speed and connectivity.
Topping Dac E30 is fantastic. Pleasantly surprised that it improves the performance over the Audiophonics essabre 9038 Dac Hat that I was using. So I now agree that USB DACs are superior to the DAC Hats even though I had one of the better Dac Hats. Anyway the DAC is awsome and has a great screen that displays the resolution in DAC mode.
Volumio software is a bit problematic. I was in the top tier subscription but just too buggy. I will come back when they clean up the delays, and bugs in particular with Qobuz. I switched to mConnect and the connection to Volumio is flawless while the interface is debatable, ie weaker than Volumio in some areas, stronger than Volumio in other areas.
AudioEngine 4 series & Cambridge Minx combo is a good choice and all of this sounds simply fantastic in my Office/Lodge environment.
