Ferrites (and the correct frequency attenuated ones for the purpose you are intended them for)can help, however they can be a hindrance as well.
Actually being able to 'see' the effects of ferrites placed on cables, ribbons and psu area's in real time is very helpful when deciding which type of ferrite (frequency attenuation, and how many to use, or indeed whether the use in that application is helpful).
John has found this out recently by removing them from certain area has really benefited his sound quality.
Some customers do benefit from having them indeed, but you have to ask why they are required in those particular areas?
Find the root cause of the issue and the cure maybe some what simpler! YMMV

I don't know if I have an issue as such here - that's the thing, you only really know with experimentation but I'm enjoying the ethernet 'upgrade' right now and can't say I'm complaining with the way the system sounds, so not something I'm obsessing about ...

Running supercap based power supplies for pi, dac and amp where viable could well have the greatest impact in terms of removing noise. Not inexpensive though unlike ferrites. LOL - sounds like a quick route to the poor house Clive! |

Don't forget - the quantities of ferrites are not solely for use on your audio gear. Whap 'em on just about everything you can think of, coz almost everything today has a SMPS.

LOL - sounds like a quick route to the poor house Clive! It could well be! If though you go down the amp route you're considering and this is with the supercap option you'll be half way to the poor house already.  You might as well do the full job! If your DAC has it's own internal PS then a supercap on that could be too hard to do. You could supercap power the Pi for about 200 notes...or if the DAC takes 5V then one PS can power both Pi and DAC. |

If I get a Topping D70, as is most likely, I believe there is the possibility to take the psu out and build an external supercap one, would need to look into that. Really not sure about the pi as mine seems to work very well with battery power but I would certainly be interested in getting a demo of the Ciunas Audio 5v supercap which is 'on tour' right now. |

I'm exhausted - just finished a good session of 'choking' ...   Dealt with smps's, router, phone line, power strips and a few mains cables etc |

Don't be silly Mike, no time for music - I'm having a coffee just admiring my handywork!!  Weekends are devoted to family so will fire it up on Monday at the earliest ... |

Still no report from Jules.
I don't know if that's a good thing or a bad thing .....

Did the ferrites make a difference or have you not fitted them yet....please don’t fit them to usb or Ethernet cables

They are all fitted but due to school hols I have not had the chance to fire up the system yet ...  I haven't fitted them to either of the cables you mention. |

Phew. Had just 30 mins spare today so have got the new Topping D70 up and running. Just a quick test to check all is working and thankfully it is. Set up was simplicity itself and I have it acting as a pure DAC, with volume controlled from my Chinese RVC. The most obvious difference to the D30 is the increase in bass - this struck me immediately. With a bit more listening I was aware of a significant increase in detail from the recording. That will be good and bad depending on the quality of the recording of course! I'm thinking the soundstage has got a bit bigger as well. Anyway, very early days, plenty more experimenting to do. |

Have fun, Jules. Enjoy the music, and please report back when you've given it a good thrashing.  |

You might as well do the full job!
