Upon installation of a second Volumio player, the web interface and iOS/Android apps show a Multiroom Devices section on the Playback screen. Tons of signal to noise and acceptably low distortion levels with negligible jitter.

The short summary is this: The HiFiBerry DAC+ Pro measures very well indeed. He did a great job and it’s an interesting read if you’re into that kind of thing. If you want charts and graphs on the HifiBerry, check out measurements over on his blog. That made them sound less boomy and a little tighter. I was getting a bit of resonance and vibration from the cabinet and shelf they were sitting on, so I propped them up on some nickels – the budget audiophile’s secret weapon for speaker isolation. They have no shortage of presence and easily fill the room with a rich, mellow sound. The Paradigm Atoms are a decent little speaker.
The NAD amp is very neutral sounding, which just leaves the speakers as the final arbiter of sound quality. Because I’m not going through any extraneous hardware like a preamplifier, I have an extremely quiet signal chain. The DAC+ Pro will also decode DSD/DSF files from SACD or Bluray. The DAC+ Pro has Burr-Brown decoder chips and two high-precision clocks tracking everything up to 192KHz and 32 bits. You can listen to this thing at any volume and appreciate the sound quality coming out of the HiFiBerry.Īnd how does it sound? Stunning, really. The available power on tap means there’s plenty available for dynamics. I think these little speakers would give out well before the amp started to distort.įortunately, lower listening levels are just as clean. With 150 watts per channel, that’s a long way off and well into painful listening levels. As long as you’re not overdriving your speakers, everything sounds good until the amplifier clips. The thing about using a powerful amp: louder volume levels still sound clean. It worked! Satisfied I wasn’t going to blow anything up, I took the training wheels off and set the max allowed volume to 50. With a reasonable maximum volume setting of 20, I turned on the amp and sent some music to the speakers. Either Volumio’s gotten smarter or I have. Initialization this time seemed to get the I2S and hardware volume settings right the first time through. It was easier this time around, having been through its quirks once before. First power-on test with the Pi was done with the amplifier turned off until everything was configured. Since I’m using the RaspberryPi as a decoder and a preamplifier, if the output from the HiFiBerry were maxxed out, it could cause some real damage. There is a small amount of trepidation when you’re driving a 150 watt-per-channel amplifier into a small pair of bookshelf speakers – any speakers, really. Now I just had to wire the whole thing up. I’d already imaged Volumio onto my 32GB microSD card with Etcher. the assembled computer and decoder module, in its case. In this case, the assembled computer and decoder hat look like a tiny piece of audio equipment.
Assembly took maybe twenty minutes to complete. With that caveat in mind, the steel case goes together really beautifully. Once online, the connection’s solid with no drop-outs in listening. Some days, I do find the wifi reception is a little poor and it might take a couple of tries to get on the network. The RaspberryPi 3B+ will talk 802.11a/c/n and on 5GHz so it is a pretty capable wireless stack. In hindsight, that might not be the best option for a device with a microscopic wifi antenna on the printed circuit board. RaspberryPi 3B+, HiFiBerry DAC+ Pro, Steel case and some tools.įor this build, since the RaspberryPi + HiFiBerry was going to be out in the open, I opted for the steel case. Really commendable service and shipping time from HiFiBerry. The whole thing arrived in a tiny cardboard box less than a week later, all the way from Switzerland. I put the RaspberryPi and HiFiBerry DAC+ Pro Bundle into a cart and hit the order button. I still had a RaspberryPi “official” 5V power supply here, so I saved a few bucks on that. Since I needed a new Pi to drive the whole thing, I ordered one of the bundles from HiFiBerry.

Those drivers had many years of jazz driven through them. A pair of Paradigm Atom bookshelf speakers were gathering dust down in the basement that used to belong to Deb’s father. I had, in a box, unused for probably ten years, an old NAD C272 stereo amplifier. After my kitchen stereo project, I’d been thinking about the next stage in my multi-room, RaspberryPi-based audio setup:
