Nice! I actually would never choose to place the Flux50 in the start of the chain(before digital) but rather on the analog part.I had a highly adventurous night experimenting with combinations of the Wel Signature AC cable and Furman Flux-50 inline power filter (knockoffs) from Aliexpress. Adventurous as in educational moreso than amazing. This is all IMO / IME, so YMMV.
To my surprise, it seems the Flux-50 inline power filter is fairly picky on synergy. I got lucky on my first pairing with it at the end of the Odin Gold AC cable going into my tube amp, but for some reason the same cable pairing into my DDC (Audio-GD DI20) didn't bode well seeming too bright. Combined with any cable (both generic and aftermarket alike) into my central power conditioning unit was painfully bright and harsh. Paired with my Wireworld Aurora 7 AC cable into the DDC was a sweet spot, which oddly enough sounded darker paired with this brighter cable than when paired with the Odin Gold, which OTOH did gel well going into my tube amp. I still plan to get at least one more for the DDC.
Wel Signature AC cable. To me, this thing is built like a tank and solid as they come, but I've yet to be blow away by the sound. Firstly RE my previously mentioned episode with the battery pack overheating, turns out the jack connector wasn't fully inserted, likely causing a temporary short out. Luckily I noticed it within enough time to disconnect it and there's still good life remaining of the battery which I might add seems non-removable. It just needed an extra firm exhertion to properly secure, and now it's not getting warm, even overnight.
Initially I had the Wels cable connected directly to the power conditioner, which for me seems maybe ideal. Briefly comparisons were it may be a bit brighter than both the Wireworld Aurora 7 blue color cable and a generic black IEC cable which I fitted with a logical mixture of industrial quality external ferrite clamps; the Wels cable sounding maybe a touch brighter with possibly(?) smoother treble and (maybe?) a touch more sense of depth than both cables. The Wels cable into my tube amp was good, but the combination of Odin Gold + Flux-50 beat it hands down, injecting more body and 'color' overall, the Wels sounding a bit too transparent or colorless, and not boding well in any case with the Flux-50.
I'm not sure if it's making any improvement; will burn-in full time for 1-2 weeks and do some more comparisons.
Did you try connect the Fux50 directly to your headamp?
-Mine is connected to my H9LE paired with a blue wireworld cable, cant remember the name. connects to iFi Powerstation.
Remember to use supporters to all those heavy cables/connectors
