@DVDdoug @AnalogSteph Thanks to both of you for confirmation of my gut feeling. Though I would not bash older technology too much. Copper wires and cone speakers are even older. I don't get any noise on the cans with the Topping. I did get some horrible noise when going through a Dragonfly...
I set up a desktop system with a Roon library via USB to Topping D50 (OG: Sinad 106, had that sitting around) to Woo WA6SE headphone amp with upgraded tubes (WE422) to Dan Clark Ether 2 cans. Is it worth upgrading to a better DAC (say D50III Sinad 123). Is the difference even audible? Nothing...
I looked at a number of power filter ASR reviews with no measurable difference. The Vinyl Attack on YouTube posted a video () that shows measurable differences with wall socket vs ifi powerstation with some "Trifield Line EMI monitor", start around minute 6. Not having any engineering...
Thanks again! Re load impedance, I've seen that mentioned a lot, including 1:10 or 1:20 ratios, but have no idea why that matters. Is there a write-up on this for dummies? I am wet scientist (marine biologist), not much EE background.
First post here with a rather basic question re a 1 into 2 pathway. I have a phone stage (Vincent PHO 701) with single RCA out that needs to send signal to either an integrated amp (Rotel 1572) or a headphone amp (Woo WA6 SE), the latter with two RCA ins.
Options are:
1) Phono stage - Y-splitter...
