I compared a few cables and it seems that deeper silver plating makes the sound more colored. Valhalla is the only one with 78 microns silver plating, the rest have 60 microns. All have Micro Mono-Filaments.
I made my own interconnects from Valkyrja speaker cable, I also cut a Vishnu power cord into 50cm lengths and used that as interconnects, it works great!
22awg Valkyrja speaker cable + Eichmann Bullets + 2 layers ERS Paper
16awg Vishnu power cord + Neutrik XLR + hardwired
22awg Valhalla interconnect + Neutrik XLR + hardwired
Valkyrja sounds very smooth, flat and neutral, nothing sticks out, everything sounds the same, it doesn't sound like real life. There is no sibilance at all. It felt like listening to background music instead of being inside the music. Neutral sound is very boring, I just wanted to turn the music off.
Vishnu sounded very heavy and smoother than Valkyrja, I liked it better at first but it quickly became fatiguing from the heavy bass. Vocals sounded more realistic but low-level detail was lacking badly. Many will love this sound.
Valhalla sounds fake and messed up, it's edgy and bright which gives fake transparency, blackness and dynamics. Everything is more distinct, nothing blends together. It sounds more exciting because everything is emphasized. It's very colored, but I still wanted to keep listening.
I was surprised that shielding of the cable didn't matter in quick testing, I connected shielding of the Valhalla interconnect and didn't hear an improvement

, it must be a very small difference. It is weird that skeptics only worry about proper shielding and don't care about what is really important.
Using the Valkyrja speaker cable nude sounded very smooth, there was no sibilance at all. I'm not sure I heard a difference when adding ERS Paper shielding.
Soon I will slice open one of my Valhalla power cords and use that as interconnects for movies. 16awg with 78 microns silver plating should make it the most colored of them all. I'm guessing it's better than the Valhalla interconnect since it has Dual Micro Mono-Filaments instead of single. The Valhalla interconnect and speaker cables are old technology, only the power cords and digital cables are good enough.
Does anyone know if it works to use a couple Valhalla digital AES/EBU cables as XLR interconnects? On their
website it says the two conductors are bonded together, are they in separate tubes?
