Hi! Sorry for the very late answer.The HDMI was added with a conversion/upgrade to a media center in mind. It's not used with the actual configuration. In the future I may upgrade this project (using a more powerful Raspberry, of course) to a more complete media center with a great sound quality.
Hi! Thanks for the interest. I've got a question for you.Do you want to stream audio files directly from your phone or do you want to just control the player from the phone?Actually Volumio supports Spotify streaming (Only for premium users, there is no way to bring this to free users), AirPlay and streaming from local or network storage, but Volumio2 is in the works (Checkout their repo, it's awesome https://github.com/volumio/Volumio2) and will include a plugin system that will hopefully bring some new features. I also use an external amplifier (The Marantz you see in the pictures) and I'm very pleased with the quality. Let me know your thoughts!
Actually, finding a power supply with this spect is not that easy and i bet a linear one will cost me more. The actual setup is already great for me so I'm not going to upgrade, for now.I think that the bottleneck in quality is the Raspbery, so a Raspberry upgrade might bring some bigger improvements than a new PSU.
That'll be awesome! But the quality is already great and I don't think i will upgrade this anytime soon.
