Upgrading DC Cables for Linear Power Supply

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.

Many thanks, Jerry, for the specific tips.  I think I will need a variety of BR and  AUVA EQ to swap around for a proper evaluation.  My amplifier's legs sit higher than the thickness of the BR Big Pads+, which I suppose means I will need to stack BR pads or just try an AUVA EQ under the amp. 

Tell me what you think about my internet setup:  I have Spectrum Coax coming into the house and leading to an ARRIS Modem.  Directly adjacent to the Modem is an ASUS Wireless Mesh Router, connected via standard Ethernet cable.  My house is from 1964 and has thick plaster walls as well as a CMU wall, yet I stream wirelessly from that Mesh Router to 2 other Mesh Nodes, one of which carries the wireless signal to my Bluesound Node N130.  This wireless setup solves a couple significant problems for me, and it sounds really good.  Considering this setup, do you still think I should consider an LPS for my router?  How about for the Modem too?  And probably a high-end Ethernet cable to connect them as well?  I thought I had read that since I was wirelessly streaming, I didn't need those upgrades, but I value your opinion here.  Thanks again for responding.  

I subscribe to the notion that small upgrades/improvements are cumulative.

In my situation I stream wirelessly to a wifi extender, then run an Ethernet cable to my switch/streamer. Recent purchase being an LHY AS6 switch before my streamer with SR purple fuse (replacing an Uptone EtherRegen). Old house, and haven’t yet got the Ethernet cable (Blue Jeans) installed under the house. You could try an Ethernet cable from your mesh to your streamer? A possibility?
