Hello everyone!

I’m new this forum and have some general questions for you.
I’ve always been into my music and hifi, but I’m new to streaming - up to now have used mainly CDs . I have a fairly decent hifi and was looking to purchase a streamer. I had been looking at something like the Cambridge Audio CXN, which is widely reviewed as one of the best streamers up to £1000. I have now been looking at the Volumio and other websites and I’m thinking I might be able to build a similar or better sounding solution.
Where’s the best place to post general questions relating to the products that I need and the best way to go about this - is there a good guide to the technology that I can read up on to get me up to speed.
Many thanks
