I have my ATC SCM19v2 on Sound Anchors stands, with Stack Audio Auva 70 isolators under them.
Fabulous in my humble opinion.
So a set of Stack Audio Auva 50 isolators under my system rack with suit their purpose very well.

Regarding the simpel DIY ferrit core throttle I linked to last week, seen above. First i want to say that my explanation that the ferrit core throttle concept i basically an effictive shielding, seem to be wrong. It actually seems that it does actually work as a filter, which is why it is claimed to perform better than the very best ethernet cables. Then i also saw this picture, on the same german forum, showing the inside of the well tested Networks Accoustics filters, that is fairly expensive. It basically looks like they have packaged the ferrit core throttle concept inside a box, if this picture is to be trusted?  A friend took one apart and it looked similar.
Yes, ferrites do not shield, they attenuate. The "trick" with ferrites is not to assume that all ferrites are equal; a browse of the website of any decent electronics component supplier will show a range of ferrites attenuating different frequencies and we need to ensure we're using the appropriate ferrites if we're going to experiment rationally rather than take a gamble. The ferrites one might use on an SPDIF cable are most likely very different from those we might use on an ethernet cable. The forum I have linked to is doing measurements on the different combinations, and listening of course. They also have experience with using a lot of other different noise reduction methods and expensive gear to compare with. If anything, i believe they are taking a very rational approach when investigating this. |

I have Gaia III under both of my subs. They transformed the performance to stop them interacting with the room. Money well spent for me.

Do you have examples of the "expensive gear" they are comparing with (and price)? One person's expensive is another's mid-range of course...
Thanks

Audioquest Diamond for example, if we talk ethernet cables only.
When you think about it, it doesn´t feel right to have electronics at all close to your streamer, in the ethernet signal chain. No matter how good power supply you have it is still a power supply and electronics, which means noise. If one can get passive filters to do the last cleaning up, that feel most logic to me.

I have a persistent hum coming from my Perreaux integrated amp transformer.
Have always had it.
Tried different arrangements to no effect.
Bought an Audiolab DC Block. Reduced it.
Shelved that and got a Puritan PSM156.
Reduced it, but not eliminated.
What else?
Perhaps try an iFi DC Blocker+

If it's mechanical hum it likely has a toroidal transformer. The windings hum and there's not a lot you can do about it except mount it on rubber isolators.

Unfortunately it's 20 years old. I think he meant a transformer... but could be wrong. If you can identify the key parameters of the transformer, you may be able to source a suitable replacement. If you're in the UK, I can assist with any soldering or crimping required! |

My streamer is the 'good for it's size/price' Project Stream Box S2 Ultra.
Have seen upgrades come up for sale here.
After following auctions, careful research, I find the ones I can afford are only slightly better (if at all) than the Project.
What would be steps up?

For me, the Pro-Ject S2 Ultra is about on a par with the Sonore ultraRendu.
For a significant step up, you need to be looking at the Signature Rendu SE which some of us are running.

I found the Project is close to quite a few, including the ultraRendu. The Signature Rendu SE is unfortunately out of my price range. |

I've never heard them directly compared with your Stream Box but I went from Bluesound Node 2i to Innuos Pulse Mini with external Zen Mini MkIII LPSU, both bought secondhand and both are excellent. If you get the chance to hear a Pulse or Zen Mini for yourself, do so. Sounds fabulous and the Sense app is a dream.
I have a kettle here in NE Leicestershire so can provide hot beverages; you'd be welcome to bring your Stream Box to compare with the Pulse/Zen Mini (they're the same thing streamer-wise) if that would be at all helpful. Message me.

Not that far away.
Only £1300 on public transport...

How about an Auralic Aries G1?

The project Stream Box S2 Ultra is certainly a decent performer.
Is close in EQ to many others that are near the same price or a bit more expensive.
I would suspect with the Innuos Pulse Mini as well.

I have no experience of the Innuos streamers, but am very impressed by their Phoenix units and have both the Net and USB units.
