I use one of these Odroid HC2 devices running DietPi and Logitech Media Server and Samba. You can plug an SSD straight into it and then screw it down onto the heatsink. It has since been discontinued and the latest Odroid HC4 looks more like a toaster. The HC2 is perfect for me and quite a cool design.

I just got a NanoPi R4S, which comes in fanless case.
Advertised as a dual gigabit router but supported by DietPi and other distro's
I might get another and try OpenWRT at some point

Thank you @Miercoles2022 for your kind thoughts, I found the challenge really fun, therapy even, trying to use as much of the original electronics as possible including PSUs, switch gear and VU circuitry. And for once its a project that I actually use!
I am now tempted to build up a purifi class D amp and house that in some similarly dated item of hifi, it’s just that the costs will be so much higher. :0(
i am wondering whether I should consider one of the lower cost ‘class D in a chip’ technologies, like those used by Sabaj etc?

@roog , Yes, the Purifi modules are quite expensive. Unless you need all that power, you could save some money by going with a lower-powered Hypex nCore model. The mid-tier IcePower modules may suffice at a competitive price point and some I think were favorably reviewed here. I was lucky to pick up a new IcePower 300A2 on the forum here for a big discount and built that into an old amplifier chassis. I’ll never use all the power it has available.
There are some well-made TI TPA3255 based products available (you may have to contact the sellers for availability) that should be very simple to implement in older chassis.

The newer Merus-based amplifiers getting a lot of attention this year are interesting, but I don’t believe there is a long track record with reliability and quality of construction known, yet. I think the bare modules for these available are still suspect for high quality implementation of the circuit. A front-runner will likely emerge soon. However, the one Merus HAT amplifier I recent received does sound pretty good, though it is low-power.
Depending on how much power you need (over 100 WPC with very low distortion will get pricey), I think there are some very good options. Good luck and happy researching!

JL ELectronics Sylph-D200 Amplifier Module Review
This is a review and detailed measurements of the JL Electronic's (JLE) Sylph-D200 stereo amplifier module built on top of TI's TPA3255 amplifier IC. Depending on the configuration you pick, the module costs US $130 to $170. You can read more about it here...

Great deal. How did you manage to get it at this price?
Thank you for your thoughts @miercoles you raise a good list of interesting options. My current class A/B power amp is from a typical over priced UK brand and offers up to 100W so I suppose that is what drives my wish to match it or better it. As they say in the UK “in for a penny in for a pound” if I’m going to change to class D it might was well be a good one! Whether I actually need the power is another matter. I must try one of the purifi based amps possibly a NAD but I am tempted by the myriad of class D chip amps especially as they are modestly priced and small thus easy to package in an old chassis.@roog , Yes, the Purifi modules are quite expensive.

I like the Hitachi with its VU meters, very smart.

A 4GB Pi 4 running JRiver Media Center on Raspberry Pi OS. Serves Apple Lossless to my Apple stuff, DLNA devices and a Pi running Moode.

Interesting design! If I understand correctly half the case is essentially aluminum cooling fins to mount the mobo on?

Gorgeous! But, aren’t you flying a little low there?

3b+ and a dac. That's it.

That's Alaska - squeezing between the peaks & cloud ceilings, following valleys in case of emergency landing.

Ditto! That is so creatively awesome. Kudos to you!
Thanks, the idea came from a friend of mine, we were both visiting the Bristol HiFi show in Feb 2020 and admiring some of the modern retro styled kit and wondered what we could do to mimic that. 1970’s cassette decks had the retro look and there were quite a few ‘not working‘ units for sale on eBay so it seemed a good choice to up cycle And probably the least likely to offend those who cherish original vintage stereo equipment as they weren’t generally good performers

Buenas tardes, soy un neófito en la materia y con tanto acrónimo NAS, DLNA; UPNP, LMS, etc... y aun encima mis conocimientos de Linux son casi nulos.
Les explico la situación actual y donde quiero llegar.
Tengo una Raspberry Pi 3b con un DAC de Suptronics X900; funcionando bajo Volumio. Y esto a través un cable RCA lo tengo conectado a un amplificador de los años 70 (ROTELYes) una maravilla, estoy encantado con el sonido.
El problema radica en que Volumio no se ven bien las caratulas. No los Lp's que eso lo hace bien al llevar la imagen dentro de la carpeta de la música, pero los Singles tengo más de 8000 y hacer un montón de carpetas e imágenes es inviable, además que se trata de un error de Volumio), ya que mi biblioteca se ve sin problemas en cualquier otro aparato.
Para evitar lo anterior encontré un programa que se llama Media Monkey, que ataca bien la Raspberry y se ven las caratulas.
Lo que quiero saber es si se puede:

Lo que quiero saber es si se puede:
- Con Media Monkey acceder a la Raspberry y reproducir el contenido de lo que hay en USB conectado a la misma.
- Con Media Monkey una funcionalidad que sería cuando termina una canción y empieza otra, visualizar en la pantalla , la carátula, el título etc, por un tiempo corto 20 segundos y después volverse apagar.
- Ya que lo malo de estos reproductores estos sin cabeza y con la música digital que muchas veces no sabes ni lo que estás escuchando, si no ves la imagen y estar todo el rato desbloqueando el teléfono es un.
