Why don’t you ask your dealer to lend you some Odins? 
But only when they have been broken in.
Your Valhalla 2 power cord should perform much better after a few hundreds hours, at least I would expect that considering what’s stated in Nordost website.
The first time I tried a Frey 2 interconnect I was sort of shocked and disappointed, but it just needed the breaking in time. After 10 days the difference was really night and day. So be patient and don’t judge a cable the first moments you plug it in (I know it’s not easy). So did the Tyr 2 perform much better after 50 - 100 hours?
I think Nordost cables do excell in vocals, drums, wind instruments and fast bass generally speaking. They are great with jazz music for instance.
@BruceW I haven’t tried Blue Heaven’s with headphones, but I’m pretty sure they would be rewarding. I use Blue Heavens and they are totally fine with my speakers despite being (maybe) bright sounding. In my case they both cleaned and enhanced the low end punch too, I was very happy with that. I guess it’s speaker and taste dependant.
All together they look like luxury chocolate boxes!
