I use a 1TB drive and find powering it individually via a Y usb lead brings a big lift in resolution. Possibly the drive was pumping noise along the power lines or the puny power traces on the Pi pcb were an issue.

Interesting, Clive... Perhaps that's why I found powering my twin Seagate 3TB NAS drives with a dedicated linear PSU [built by Duncan] made a massive difference to the sound I get from my RPi, see here:Originally Posted by Clive

You should try it, if you think that what you did made a difference, as it essentially takes the concept a few stages further!

Hi Marco, some day I'll compare NAS to my self-powered USB approach. Ethernet connection may well be better though I suspect I've cured most of the USB ills with the self powered drive.Interesting, Clive... Perhaps that's why I found powering my twin Seagate 3TB NAS drives with a dedicated linear PSU [built by Duncan] made a massive difference to the sound I get from my RPi, see here:

BTW I had to prevent the HDD from feeding power the Pi, I used a solid connector with the +5V contact removed. It may be though that I end up moving to the Allo Sparky from the Pi as these seem to give better results but are more hassle to setup.

Oh my god! There's nothing wrong with the bidet is there?
“Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".
“You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”
"You don't have free will. You have the appearance of free will.”
“There's a war out there, old friend. A world war. And it's not about who's got the most bullets. It's about who controls the information. What we see and hear, how we work, what we think... it's all about the information!”

I found that powering my USB hard drive from a USB hub, rather than the Pi, gave a significant improvement in SQ.

Powering your SSD/HD separately with a good PSU, or any other attached USB device for that matter and disconnecting the 5v at pin 1 on the USB data lead is a very good idea.
For those not good with DIY and soldering of such small items, SBOOSTER (makers of the PSU's) do a USB pass through adapter that has pin 1 disconnected. Their example use is with a DAC, but it will work the same. They charge 21.50 Euros for it though, which is a bit of a cheek. Here: https://www.sbooster.com/sbooster-tweaks/
I don't know if it has any other components inside, I suspect not.
Must get round to building a rpi, had one on the drg board for a while - Single box/RPi/Linear PSU/1TB SSD, just not had the time.

Hi Lee,
Its quite simple. I have a 500GB Samsung Evo 850 SSD. Its big enough to hold over 9000 tracks as WAV and roughly double that as FLAC. It is powered directly from the RPI3 which is battery powered. I tried powering the SSD from a separate battery but to my ears it sounded worse. There are no drop-outs on playback which I did have occasionally when streaming over the WiFi. I am using the Caiman SEG (12V battery powered). I hope that helps!
Cheers
Alastair
