will it work on pi 1

[Miss Sissy Princess]

That did it fine thanks Tim
Is it worth getting a newer pi, say a pi 3.

It is to me, because I want fast WiFi networking to pull the music from my NAS and serve web pages quickly. I want the processor to have enough speed to rebuild the library rapidly and keep up when decoding from MP3, FLAC, ALAC, etc. to the raw output to the DAC.  I want to minimize jitter and prevent any kind of dropouts.  Speed is good.
