Hello,
I recently decided I needed to make some improvements to my system, note, I primarily listen to music in vinyl format as a personal preference, however, I also to a lesser degree listen to digital music on Apple Music or streaming from BBC Sounds. I also do not have any Hi Res Audio files or resources so cannot comment on that.
So, why am I writing this, well I am considering adding a DAC to the system. In the process I began questioning why am I using Bluetooth to transmit the audio, yes it's convenient but is it killing my sound? Ok, once that was decided it could be a culprit, I thought should I introduce a Raspberry Pi streamer and then thought to myself, why? That's when I remembered that I had an Apple TV Gen 3 with Toslink optical out. I connected this to the system and wow, there was quite a difference compared to Bluetooth. The audio was much clearer, more noticeable highs and midrange, tighter more responsive bass. I continued A/B testing and will not go back to Bluetooth unless necessary. Bluetooth by comparison sounded muffled and distant, clearly less concise (likely due to the lossy compression in BT).
Other considerations:
- Airplay is lossless streaming via WiFi up to 16bit/44.1KHz anything above that gets downsampled
- Noticed occasional jitter on my receiver with it's older internal DAC (Pioneer Elite VSX-32) - 10yr old technology
- A DAC within the range of $200-250 may be in order (considering Schiit Modius or Topping DX3 Pro or other)
- Apple TV Gen 3 is limited in its native apps, but can stream anything from new apps running on an iPhone
- Home Sharing enables to see audio files on my MacBook Pro
I'm set on using AirPlay for now as it's clearly an upgrade but a DAC could be in order as well and should help with the jitter I experienced. I'd love to hear feedback and your own experiences with streaming.
TIP: For anyone with an Apple TV 4 or 4K, Apple has unfortunately deleted a Toslink optical out, however all is not lost, apparently you can stream the audio from there to an Apple TV Gen 3 (if you have one). This is a more elegant way of doing it than getting an HDMI audio extractor or god forbid going Bluetooth out. This is a great tip from Darko Audio, link below.
