Upgrading DC Cables for Linear Power Supply

I've been researching and thinking about your comments re: isolation in my system (after 40 years- ha!).  Based on your experiences, can you tell me if this is a good path for starters?  I am thinking tiny, microphonic vibrations might better be handled by Black Ravioli Pads, and larger ones by Auva EQ.  Is that good reasoning, or is this whole thing a crapshoot of trial and error?  Here goes:

Node N130 (light and plastic body).  Sits on sturdy steel equipment stand, with sturdy wooden shelves on Granite Floor.  Node's flat base area is only 3"x4"-  Try (4) BR Small Pads very close together under Node's flat base area in center.

Teddy Pardo LPS for Node (next to Node)-  Try (4) Black Ravioli Big Pad Plus 

Weiss 501 DAC.  This sits in a wooden studio equipment rack on coasters, on a shelf thinner and less sturdy than eqpt above.  I suspect more vibration here. - Try (4) Stack AUVA EQ  isolators. 

Tyler Woodmere Speakers (200 lbs each)- Try Large Stack AUVA speaker isolators

With this mix, I should be able to swap BR Pads and AUVA EQ between equipment to determine best scenario.  Then I need to think about Preamp, Amp and Phono Preamp.  Please let me know if you like this approach, or if you might offer a better one.  Thanks!

@rtilden If you're speaking to me I'm loathe to give advice on specific isolation needs. As mentioned previously I've experimented with a wide variety of isolation devices over the decades, I've chosen specific devices based on the exact voicing I'm looking for, my needs may change over time which is why I keep a wide variety on hand. 

General advice, the lps for digital equipment isn't that important in the whole scheme of things. Dac is important, sounds like you could use some improvement here, should sit on something more substantial and then add the footers. Most around here seem to use the Townshend or Isoacoustics Gaia's under speakers, don't know about the Stacks with those spikes, people seem to prefer isolation from floor vs coupling to floor. Best isolation for me with turntables, tube preamps, amps has been Stillpoints. My entire system sits on a 2" concrete slab on suspended floor which has been supported with multiple floor jacks, no tall equipment racks, everything on custom sand boxes, top plates use steel, various thicknesses of aluminum with custom vibration sinks or various woods, which top plate chosen depends on voicing I'm looking for. Then all the various footer combined with various top plates in order to attain voicing I'm after. So now you see why its difficult for me to give specific advice.  Experimentation is the only way you'll find what works for you, sounds like you have a good plan thus far.

Thanks for the response, SNS.  Yes, I was asking you and Jerry, as you have been gracious with your advice.  And I appreciate your explanation of all the variables in your system/room.  I was drawn to the Black Ravioli and Stack AUVA products due to the numerous positive reviews.  Just FYI, those AUVA speaker isolators are available with felt pads instead of spikes, which I would need for my polished granite floor.  

I'm travelling for the month of July, but I think I'll start my experimentation when I return.  If I learn anything exciting, I'll share with this group.  Thanks again, from Winter Park, FL.

I was a sceptic with isolation, at this price. Had tried Vibrapods and sorbothane to little or no discernible effect.

When I got BR Big Pads under my Perreaux amp. Wow, is all I can say.

I would suggest BR Big Pads for your streamer. With my amp, a noticeable step up going from pads to Big Pads.

Big Pads+ for your Dac.

Perhaps the smaller BR Pads for LPS and router. Try an LPS for your router? at some stage as well is a possibility. I ended up with a used FiiO PL50 to good effect (although will swap that with a now redundant Plixir Elite LPS). I've been snapping up used SR Orange fuses for my LPS. A contentious issue, but I see/hear benefit.

I originally bought the Stack Audio Auva 70 under my stands and ATC speakers. They were better than the Isoacoustic Gaia I had.
