raspberry pi 2 as media player

[terrible]

I am listening to the raspberry pi powered by a teradak linear PSU and it's sounding shockingly good
Improved dynamics, tons of more detail without being edgy and bass texture has improved the most

A senior FM visited me today and help me setup speakers
And make room more sound friendly
Without that happening I had almost concluded the lpsu has spoilt the sound from what it was before
I will keep the Details of what all.changes were made for a separate thread

This PSU is for $44 and is every penny worth for someone using RPI as a music pc

I have got the PSU for a few days to try it out

Can you point me to the PSU you are talking about?

TeraDak U9VA Linear Low noise Power Supply

Its marketed by teradak as lpsu for one of its other component the company sells
But the specs are perfect for raspberry pi

Has a USB type connector which has 5 volts 2a and other is a DC jack outputting 9 volts

The changes could be because of the placement of the speakers and improved room acoustics?

Would be interesting if you left everything the same and went back to using the old power supply?

Would the improved dynamics and detail still be apparent?

Anyways, good that you are enjoying the music.

Hi regehA
Tried that

Improvement is vast
The leanness goes away with lps. The bass is fast and tight with lps
My guess is imaging wise there is not big difference wighbor without lps but tonality changes a lot for good with lps

Do they come with Micro USB for the Pi?

For something like this @ DC-30W-TOUCH 5V/3A Power.

Hi regeha
Check the link in my post which is reply to FM terrible post
The link is for a teradak lps only and i am using same
Micro USB port is needed on pi side. On the PSU side one needs a USB a or b , forgot which and the required port is there on the lps and another DC jack which can output 9 volts

One thought - Will it be possible to design a PSU by one of our expert FMs for pi?.
It will be more handy if you want to have nice enclosure for RPI where pi, PSU, Trafo and connectors cane added. It can be enhanced with an arduino based display for the songs played.
There was group buy in diyaudio for Logitech Squeezebox power supply which matches the RPI power requirements

I have U9VA as well. But I think that's an older model. Thus missing the USB port. [emoji26]

However I have a DIY kit for regulated power supply. Thinking about building a Pi psu out of it. [emoji4]

The one I have has written u9 on it

Does the one you have output 5 volts ?
If yes make a cable with one side dc Jack and other side micro USB port

Also over riding the fuse and protection circuitry is also critical according to many reviewers
I have done that and there is no way for me to test with AMD without as wire is soldered on board

 

[regeHA]

@rikhav @saikatbiswas82 - Is that 5V 3A? 3A is a necessity for Pi 3. Even 2.5A might not cut it.

I do have 5V 3A power supply, but its with USB C, charger for the Nexus smartphone. For Pi 2 I'm using a Sony charger, 5V 2.1A, working great.

Regeha
Component takes current how much ever it needs
So 3A not an issue

Voltage should be as per whats needed

Thanks, ordered a couple.

What?
Teradak u9?

Boy, you are fast , very fast

Product should reach you soon as you in neighborhood:clapping:

Cannot argue for that price. Its not "expensive" like HDPLEX.

Yes it has U9 written on it. But missing the USB port. The DC jack outputs 9v @ 1amp. Here are the photos:

I believe a PSU with 5v and anything greater or equal to 2 amp is required (or recommended) for my RPI & Digi+ combo. I am using my nexus charger (Asus make) of [email protected] right now. Its working flawlessly. Will be making another LPSU with 5v@2a. I believe 3a will be having a little headroom which is nice. So a 5v 15watt LPSU will be more that sufficient with Pi along with its HAT board.

Yes, TeraDak U9VA from A&B Systems.

If you use the USB port only of U9VA for RPI, the maximum current PSU can draw woould be 9w/5v=1.8amp. Which I think sufficnent for RPI & digi+ combo.

BTW, I bought this Teradak for my Peachtree DAC. I have no intention of using it with RPI. Will be making a better LPSU (maybe better that Teradak) for RPI.

 

[rikhav]

What a coincidence

Going to try the teradak with a Peachtree dac in the evening

I think you won't be disappointed. If you have the Pi & Digi+, carry the combo with you to test the system out.
