OT: Music player with substantial speakers than can play things like mp3, wav files from an SD card or USB pendrive

[rhkramer@gmail.com]

I'd like to find a fairly large (I mean not a tiny hand held thing that uses 
batteries and has tiny controls) music player that can play things like mp3, 
wav and other music files from either an SD card or a USB pendrive.

I'd prefer to be able to plug it in to a 120vac power source (ie., not use 
batteries) and have at least one of:

   * fairly large speakers for good sound
   * output jack for headphones
   * outputs that can connect to a "standard" audio amplifier / speaker setup

I'd like to find something prebuilt, rather than making configuring something 
myself from anything like a Raspberry Pi.

I'd like the controls to be on the order of the size (and style) of those on a 
"standard" stereo system.  (I mean, among other things, I don't want tiny 
controls, nor do I want to have to use a keyboard and monitor.)

I've done a little bit of googling and searching on ebay without turning up 
anything.

(There are things that would be nice to have, like if I'm playing music from 
an SD with 100 or more songs, it can remember where I left off when I turned it 
off and start from the next song when I power it on).

Is anyone (on here) aware of something like that?
