How to play digital audio tracks?

For my listening
In the bedroom I use an old phone with an SD card in and have a bluetooth amp great as it also has a DAB radio.

In the lounge I just have a micro amp with bluetooth SD card input etc wired in to my main HI Fi speakers ad to be honest teh sound quality loss is not really that noticeable as it is MP3 via bluetooth

But the op already has an amp that works fine. He's also pointed out that a large part of his collection is on USB drive so how would this option serve his need?

Edit: apologies I see that this does have USB. But still, his amp currently works.

Also, these things crack me up. 400W amplifier running off a max 5A 12V supply...

very easy to transfer from USB drive to SD card for use in an old phone.

I keep a copy on a USB drive for back up and use in the car (as well as on a external HD drive)
