Just added a 9.5 inch dampening plate to the center of my Rossini master clock. Pretty excited as the bass and midrange have noticeably improved. I have Nimbus discs under each of the four feet.
A big shout out to Todd Snyder from The Sound Environment for the suggestion.
Update: best practice is to remove the Rossini feet including the black base with two screws. You then position the Nimbus perimeter over the two screw holes. The extra resolution is remarkable!
Try removing the Rossini feet - common wisdom (from both HRS and dCS owners) indicates this should be done so the chassis can rest directly on the HRS bits.
I am still waiting for my set of Vortex footers and 14” damping plate to arrive. HRS is definitely slow shipping.
See update above.
I think what is confusing me is your typo (?)
Perhaps instead of “remove the Nimbus feet” you meant “remove the Rossini feet” ??
Yes, sorry for the typo.
Good report!
Extra resolution - I can’t wait to try out my inbound Vortex + damping plate.
I will try the Vortex feet at some point.
They recommended clock first over DAC?
Yes, Todd says the clock is most sensitive to vibration and power cord effects. He believes it should have the best power cord in the system as well.
It’s funny - I ran things through ChatGPT and it stated the Clock was the most sensitive as well. The Upsampler was listed as the least sensitive.
When doing research on my own (non AI) many mentioned the DAC should be the initial starting point.
While I have just one set of Vortex + Damping plates arriving for testing purposes, my ultimate intention is to have all three Vivaldi boxes outfitted with footers and damping plates. I also plan on testing the bits with my DarTZeel boxes as well.
Greg,
My advice is to be careful with LLMs like ChatGPT as they train on very small data sets in audio, often based on random person observations. I work in AI and strategy and have noticed a boat load of bad setup advice. The good thing is that they often lead to original sources and that person (or firm) we may already know from here, Hoffman, or WBF and have some idea if they are relatively trustworthy.
Oh trust me - I love doing research and AI models are just a small part of the overall mix I use to come to my ultimate conclusions.
I have seen some egregious errors and factually incorrect statements made by AI agents,
I figured you did but just wanted to put the warning out there.
