Extending stereo with streaming capabilities
this is my first post, this discussion board is a little confusing so forgive me if I'm posting in the wrong section.
I know very little about audio setup and have been googling for a few hours to find a good answer but have found very mixed results, thus I decided to seek help from people who know their stuff.
I use RCD-M41 amplifier with standard SC-M41 speakers. As you know, this amplifier is equipped with bluetooth and this is what I've been using for streaming music, namely I connected my iPhone and stream music to the amplifier with Spotify. However, this has become an annoyance since it drains the battery and whenever I do something on the phone, like watching a video etc. it interrupts the streaming. So I've started looking for alternatives and to be honest I haven't been very happy with bluetooth sound quality, playing a CD sounds way better but then I don't have that many CDs...
First I looked at Echo Input, very cheap but discovered that it comes only with 3.5 mm input and bluetooth. I hooked up the device via the 3.5 mm input and it sounds very quiet and quality is even worse? Pairing via bluetooth solves my iPhone battery drain problem but doesn't improve sound quality... I read that Chromecast Audio connects via digitial cable to the amplifier so the quality should be better but then it's been discontinued.
So I started looking for other streaming devices with WiFi - so the device connects to the internet and via the digital cable streams the music into my amplifier (which is the best solution, isn't it?). However, the prices of these devices blow me away. I found yamaha musicast wxad-10 which is affordable but it doesn't come with a digital output either from what I read so it seems it's pointless or am I wrong here? Raumfeld Connector is affordable too, however, the reviews of audio quality are mixed..
What do you think about this? Maybe I'm thinking wrong because my stereo isn't powerful enough to produce clearer sound than that of Bluetooth, I don't know.. Is there any specific device you could recommend?
