Here's my portable system:![[Image: 4fcZpS7.jpg]](https://i.imgur.com/4fcZpS7.jpg)
It's a Raspberry Pi Zero W with a 200gb SD card full of FLACs, an Apple USB -> 3.5mm dongle (which measures well: https://www.audiosciencereview.com/forum...ters.5541/ ; despite costing £9 and being the size of a cigarette there's a quality DAC in there! https://www.cabledo.com/apple-usb-c-digi...-teardown/ ), plus some adaptors so I can power it via USB C and plug in my 1/4" Sennheiser HD 595 headphones (I'd have included them in the photo only they're currently disassembled so I can paint them). Despite only owning the gimped EU Apple dongle it's just about loud enough for these headphones. I control this via M.A.L.P., a great, free Android MPD client. The lego might look a bit old and tatty; it should, as I played with it (most of it; I bought some new pieces recently) as a child in the 70's!
My main music system is the same software, but on a Pi 4 with an external HD and a "proper" DAC and amp. To make moOde easier to control I added an infra-red receiver and used some of the unused buttons on the DAC remote, which I blogged about here: https://poldieblog.blogspot.com/2020/12/...-pi-i.html I switched to moOde from just a bare Raspbian install as it was the easiest way of accessing a parametric EQ to tweak my headphones:
