Default Raspberry Pi Audio Beginner Help Needed

So I am researching my options for a Rasp Pi based audio hardware, and I have read many of the threads in this forum. Much of it is beyond my level of understanding, but I am learning.

What I have:
Raspberry Pi 3 v B
Harmon Kardon HK 3370 Receiver
Magnepan .7 speakers
DIY Sub
Other stuff:
Overnight Sensations (most recent build)
Voxel Sub
Misc DIY speakers in various states of build/mod
Several cheap board amps in various states of build/mod
What I want:
Good to great sound quality, amazing not necessary at this point
Playing audio from USB connected hard drive
Streaming via Airplay, Spotify, and/or Tidal
Relatively low cost, <$100, less is better
Room for upgrades and expansion
"Hat" configuration on Pi seems handy
Want to experiment with various software packages Moode, Rune, Volumio
Do I just start with a HiFiBerry (or maybe a cheap clone)?
Any good threads, blog posts, websites to learn the basics?
Other suggestions for the beginner?

I like my HiFiBerry but I don't hear much of a difference over the generic USB sound device I had been using previously. I only went with the HiFiBerry for the pedigree, to remove any doubt I had in that USB gadget.


I use Logitech Media Server, that is where I started years ago with the original SLIMP3 player.


I recently (within last year or so) tried the other players but found them to be slow in the response department (like changing volume). It seemed they all forked form the same code and all of them actually adjusted volume the same way, and that was by manipulating the actual stream rather than just telling the default sound device's mixer where to set the output level.


And none of them at the time had an interface as nice as iPeng on the iPad I use for controlling my playback.


Recently, the Logitech Media Server has switched to Spotty for Spotify playback and it has gotten very solid, so I'm using that for my streaming service. Very happy with it.

My suggestion.

You have lots of stuff you can re-purpose, to minimize additional costs. Keep your working system (HK-3370, Magnepan, Sub, Sensations) intact and far away from your educational system. You'll need something to listen to while your educational system is in various states of repair.

1) Try loading one of the many headless players on your RPI, and use a pair of headphones to get it working. Hopefully its an RPI3B model. The RPI headphone jack is low quality, but sufficient for starting. My preference was Volumio2 as it was easy to install and use. There are lots of players to try if you want.
2) Try to setup remote access to the RPI so you can work via a PC and a network connection. This requires some PC tools and basic Linux knowledge.
3) Try to get one your experimental amps and experimental speakers working. Eventually you could connect the RPI heaphone output to one of your experimental amps and speakers. Hopefully the speakers are full range or at least have an XO.
4) If the above goes well, you could buy a DAC hat or USB DAC for your RPI to improve your sound quality and get proper line outputs. If you're confident you can connect these proper line-outs to your HK-3370 and start using the working system. The RPI becomes just another HK-3370 input option.
5) Then try some DSP on the RPI to equalize and improve your sound quality via speaker EQ and room EQ. It would help to have a measurement mic at this point.

Hi,

I have made positive experience with both Volumio as well as Max2play on my Pi3 with Hifiberry dac and Hifiberry Amp.

Both offer Airplay and more. Check out their websites. Volume is free. Max2play requires a license fee, if you want to use advanced features.

Kind regards

Michael

Great suggestions so far. I greatly appreciate your expertise!

I do generally keep my "daily listener" system separate from my experimental systems. Most of my experimenting is done with the OS+Voxel speakers plus various cheap board amps. I have basic working knowledge of the RPI as I have used several on other, non-audio, projects. I mainly use VNC from my laptop so no extra monitor.

I will try some of the software suggested here with the headphone jack. That should get me started.

Any suggestions for specific DAC hats? I know this is starting down the rabbit hole, but I am gonna start down that hole sooner or later. I just need a starting point that isn't too expensive.

I use Volumio2 with an Allo Piano2.1 . It costs about $50 and it works out of the box. It sounds good and gives you easy to configure outputs and subwoofer options. Volumio (like all of them) support NAS and webradio and many other features.

@DonVK -- After your advice and reading this thread, Current fave cheap DAC HAT for Raspberry Pi?, plus other related reading, I think it is going to be the Piano 2.1. It is not expensive, looks quality, and leaves lots of room for upgrades -- power supply, kali, etc. It will allow me to experiment and try all the software variations.

Thanks so much for your assistance.

So I received my Piano 2.1 and have it successfully running on my RBP. Thanks for all the advice and help! I am checking out the various software packages. Current have Volumio running.

I recently completed a Voxel + Overnight sensation build. I am looking for inexpensive, but reasonable quality, amps to run the three. I still want to keep this test system separate from my main everyday listening system for now. I was thinking of getting three of these, Yuan-Jing TDA7293 Dual Mono Amplifier Board Set 2 x 85W from PE. I want to learn to hear subtle differences in the setup. I donít need really high volumes with my normal testing/listening habits.

Another option would be a Lepai 2020 for the OSís and something else for the Voxel.

Any thoughts?

That was fast

What about class-D amps so you only need a single supply rail.? I have used the Sure modules OmniDirectional - work in progress and they are electrically quiet and sound good. The "actual" power levels you get will depend on the supply voltage and speaker impedance (like all amps). This route is more work as you need to "kit" your own amp.

They have a number of fanless modules that would run off a 12VDC brick and you'd realistically get [(12VDC-2VDC)*0.7]^2 / 8ohm= 6watts or increase the brick to [(20VDC-2VDC)*0.7]^2 / 8ohm = 20watts.

I like that idea and your setup on the other thread. I have a Meanwell 24 V 6.5 A that could probably power a couple of those pretty well.
