One of the more useful things in PicorePlayer is that you can set up something to start playing on your Rpi on a Hard Startup.... This couold be a playlist, Radio Station etc.. etc.
I use this for a small system set up in our main bath. I got a Teac Amp/Dac combo with the Rpi feeding it all hooked to a Surge Protector plugged into a Wall switch. This is all on a shelf about 10 feet high. So, all my wife has to do is throw a switch and her favorite radio station is playing. She uses this every morning.
One question I have, When looking at your picture of your Rpi Case, it looks like there are layers of plastic.... Not sure I understand this. I also have a clear case with just 6 sides that lets you see everything inside.
Also, try out the Rpi in your main system and give us your impressions...
When looking at your picture of your Rpi Case, it looks like there are layers of plastic
Yes, it is a layered acrylic case from Zebra . It was a bit of a puzzle to assemble. Each layer was protected on both sides by film, so I had to remove them first. Then insert board, stack each layer and screw together.
Yes, all of my Acrylic Cases come with 2 layers of film protecting the.
Do you know the purpose of the layers of plastic are for the case?
Ease of fabrication? Some of the layers are identical.
Is, I was trying to understand why they used layers, instead of 6 sides for the case.... I also have an acrylic case that just has the 6 sides.
Yeah I think its all about fabrication and has nothing to do with magical audiophile properties.
Of course it might be some sort of harmonic resonance cancellation and tuning due to layering. The layers could also scatter and deflect any EMI/RFI.....Hmmmmmm, Nah.
IMO it is 'worthy' of being placed in someones main system.
Only thing is, its difficult to get over the mental thing of having an inexpensive device playing with multi-thousand dollar gear.
Bryston thinks it's worthy. Their Pi is stuffed into a nice box with LCD screen and it's only $1295
"Built upon the Raspberry Pi and HifiBerry platform, the new BDP-Pi is faster and more capable than our classic BDP-1 yet fits in a chassis 1/3rd as wide as our full size gear..."
It seems it does not support DSD. And for PCM it can only go up to 192K. So it does not support DXD.
Let me know if my understanding is correct.
Yes of course its worthy, they stuck it in a fancy case for the audiophiles that can't get over that mental thing I posted about....plus of course to enhance profit.
2A @ 12V?
RPIs generally use 1A @ 5V. The uRendu uses 1A @ 7V.
The BDP-Pi also has an LCD display and supports external USB disks and DAC, so they have to take those into account in the power budget not knowing exactly what devices customers might attach to it.
I'm sure the BDP-Pi doesn't draw anywhere near 2A but Bryston may have spec'd it at 2A to be on the safe side should customers decide to use their own power supply. USB disks can be relative power hogs especially during spinup. And -some- DACs derrive ALL of their power from the USB port.
When I measured the uRendu I saw that its current draw was only 200mA (0.2A), maybe a tiny bit more only during bootup. With a USB DAC attached it drew a total of about 240mA from the power supply. That "extra" 40mA was for the USB receiver in the DAC. On another DAC it remained at 200mA as that DAC supplied its own power to the USB receiver. Some other DACs, like those of the Dragonfly variety and similar are powered entirely from USB and could draw even more current.
You have a good point. One doesn't have to spend a fortune to have a very good sounding system.
But some of the great sounding gear is not cheap.
Yes some of it is not cheap.
One day soon I will be checking out the power supply you like.
I just finished a review that will be turned in today for layout that compared 3 relatively expensive power supplies. I'm curious how your selection sounds.
I had no trouble getting over the 'mental' thing......
It took me decades to come to the realization that "You have to spend a lot of money in this hobby, to realize that it doesn't cost a lot of money".
