-Removed-I have a (I think) fairly high tech old fashioned multi part system of a rega planar 3 deck, rega CD and amp and matching speakers.
Basically, old fashioned hi fi buff
Wanted a 'stand alone' CD player for other room, having had a Bose system. Anyways, happened upon the ruark 4 . absolutely brilliant sound. Plus, Bluetooth receiver Also, my son told me how to stream Spotify, and that is all I now play through that player. Now a Spotify subscriber. Not sure about your streaming suggestion, but would think of similar quality.
The ruark isn't cheap (around £650), but once you've got if, you've got if
-Removed-The only time I listen to music, aside from on bluetooth headphones using my phone (15% of the time), is when I am working at my computer (85% of the time), so I just listen to mp3s and the occasional CD using my PC and a pair of not very expensive (but not too shabby) Behringer MS40 speakers. It's enough. In a kind of ideal home in my imagination there would be a music room with top gear and a nice sofa and nothing else except for a bookshelf, but in reality I probably wouldn't spend much time in such a room.
I have tried spotify and deezer. The choice depends on several factors. a) How convenient you find the site navigation, which is mostly a matter of taste. b) Deezer offers a free version (all the music, but with silent/visual adverts) and a paid-for version. Spotify (correct me if I'm wrong here) offers a lot less music than deezer in the free version. c) In terms of network activity, spotify will log-jam your LAN and unless you have broadband you may not be able to do anything else with your Internet connection while it is running; deezer is a bit less bit-torrenty. d) The genres you prefer (again a matter of taste); not every Internet streaming service has everything you might want to listen to.
