My favourite gadget of all time is the Logitech Squeezebox Wireless Media Player. I have two of them. Sadly the version I have is no longer manaufactured but there are a couple of newer versions that will also do the job.
Basically the Squeezebox is a streaming music player that you connect to your hi-fi. Once set up it allows you to connect to a source either on the interent or to your music stored on a computer or NAS and play it through the hi-fi. I have one in the Office and one in the Living Room. My music (mostly on vinyl) is in the course of being digitized as 320kbps MP3’s and stored on a 4 disk RAID5 QNAP.
I will write a blog about the digitizing process at a later date.
