I have a Digi+ Pro coming from overseas, how are you playing back music now, through USB?
Also interested in what battery pack you are using. If you noticed a huge difference I may want to look into that for myself. Thanks for any help on the battery pack question.
I got the digi+ pro because it is supposed be lower noise + better spdif connector (gold), also that one doesn't use the basic crystal the other models do. I have yet to start to fiddle, not sure I will go LMS route, I still have to figure out Volumio I believe I want to get that working first. I'll give that a shot today at least with USB until the Digi+ Pro comes.
I have a great idea for a case, essentially the basic pi3 case without the top, then taped on top with electrical tape an older 1/2 of the pi 2 case. Duct and electrical taped together not WAF friendly but it will be on the floor behind my rack :)
At the time I ordered mine there was a warning on the HiFiBerry site that indicated some special software requirement for the Digi+ Pro. Must have been cured with the latest version of PiCorePlayer because this warning is no longer there. Both Digi+ and Digi+ Pro appear as choices in PiCorePlayer so I thought I would give it a shot.
Battery in question is for sale on MassDrop. You have to register and be signed in to see pricing but I've bought a couple things there and been very happy so far. Just a few of days left on the battery packs, then it goes away.
Link below: I got mine for about $40. Four lights for indication of charge level and I STILL have three this morning and I'm at 36 hours on.
I picked up a battery power supply from Musical Paradise. My intent was to run the dig+ board from it.
Right now I'm listening to my second system a lot via a Chord Mojo. To my ears the Mojo sounds better via usb. So I tried to power that Raspberry with the battery supply. For whatever reason, I think the cheap apple charger sounds better. What the heck?
Next up, I'll use the battery to supply 5 volts to the Mojo via a split USB cable.
So many things don't make sense!
Anyway, I ended up with a package of 4 headers to send power to the digi+.(for my other system) As shipping costs more than the dang headers, I'm happy to send some out to folks in the us who need them.
And remember, those cell phone batteries have really cheap noisy voltage regulators in them!
as I didn't think they had enough current capability to run the Raspberry Pi.
The Wall Wart that came with the Raspberry Pi is rated at 5.1V/2.5A.
Already had the 24,000mAh battery pack for travel and emergency use as everything in the house seems to a require USB charger and all of my outlets are hidden behind furniture.
What's a 'header'?
Most things I've read says the top hats from HiFi Berry (and others) improve with their own clean power source.
On top of your digi+ is a blank soldering hole labeled R5 ( I think...I'm at work) You can attach wires or in this case a header (Im obvs not an EE) to hook it up to a regulated power supply or battery or whatever to power it directly. You can go further and cut two of the pins that connect the top hat to the pi and then power the pi from another source to give each component a different power supply.
You might recognize my office speakers.
Terry left them at my place in Utah on his way to Vegas for what was probably his last C.E.S. I was on my way to Vegas as well so the next day I tossed them in the trunk of the car. When I mentioned that he had forgotten them he replied, "I left them at your place on purpose, I wanted you to have them."
Yep...that was Terry. I am still trying to get thru the piles of equipment he traded for (and most of it he never opened) I traded him a nice Revox G36 for a pair of IM-Bens. I know he never touched it.
I also have a pair of Rat-pipes. A smaller version of the Abby with a radio shack driver. They give me so much pleasure.
Boy do I miss lunch with that guy. A sweeter man has never walked the earth. I'm glad I have his talented wife to still call my friend.
I was living in Utah from Late 90's to mid to 2007 hung with the Utah Triode Mafia (ElecronLuv, et al.) in those days. Made it to to Walla Walla to see Terry once for a get together plus a few VSACs and all that.
Do miss him. One of a kind!
Ha...you are probably right..I moved here in 2003 I think. I miss Josh's amps too..loved going over there to get a listen to Terry's big system.
I remember when he brought back a computer to play music files ( to make this a legit post in (Computer Audio). I told him he was nuts.
And now I'm Roon and Tidal all the time. I should learn to shut up and listen.
Not sure how this works, But I put in my credit card and 'joined'... Not sure if I bought one or not.
I'm going to use it for my phone mostly.....
