We all know the fuse and cable tricks part of squeezing more out of our regenerator. I thought we needed this thread to share knowledge. Please feel free to add your tips and tweaks. Or kind criticisms.
Fuses I have tried best performance to least performance
- Synergistic Research Purple
- Audio Magic Beeswax Ultimate Premier
- Stock PS Audio Gold Fuse with white powder
Cables to date. Waiting for AQ Dragon HC with C19
- 10 Gauge Iconoclast BAV C19 Wattgate
- Stock PS Audio Cord
After I modded my DS DAC with EMI/RF absorption i had originally bought some 3M AB7050HF absorber but it was not good for all of the components Ted recommended be covered so I chose a AB6000 series for chip board Parts and Transformers. I only used some of the AB7050HF when I ran out of thinner stuff and need an RF wall to shield display radiations
Anyhow it works like MU Metal and you can lay it near stuff I learned. It is a magnetic field absorber too. I first tried near power cables coming in P20 no affect. Having just did a purple fuse and a Dragon HDMI cable and Shielding wrap of AMP power cables my noise floor is really really low. So I started listening intently and decided I’d try moving the absorber AB7050HF piece I had left over the top cover listen same song then move it. Then same song and move it to see if it works or snake oil. I also tried masking tape it on front panel.
Low and behold I found a sweet placement spot that further eliminates hash. Then I looked up digital images on line only to see what is under the top cover. I appears to be a ribbon cable routed over Torroidal transformer. I have yet to try the sheet taped to bottom panel. Also looking at 3M Spec sheets it says it works for ribbon cable. Interestingly using the sheet at back right corner where ribbon cable terminates was the noisiest location for the hash.
I intend to play some more moving it over and around different digital boxes and cables and possibly see if any audible improvements or degradation.
Here are photos of best location for the sheet. Plus what is underneath the cover also material data sheets. I paid about 80 dollars if I recall. If playing around further quiets things in my digital chain.
Anyone remove the top cover on the P20 or know how to? Placing some shields or absorber over the FPGA or digital display electronics might be a audible boost like the DS DAC.
