Nordost Tyr vs Valhalla

I recently tried some new interconnects in my system,(posted), primarily from source components. I am currently using the Shunyata Aries with RCA. This is a very fine cable. I tried the Nordost heimdal and though this was quiet and good dynamics it lost a lot of mico-dynamics and natural timbre that the Aries had. I did try the frey some time ago with a completely different set up and did not notice much difference between the heimdal but that was completely different set up. I now have a pair of Valhalla's on loan and am very impressed. Imagining is much more precise, micro dynamics are much improved, bass is extented but more controlled, timbre is so very nice. I am hearing little nuances that I never heard before. When I go back to the Aries, all the information is there but not with the degree of clarity and three dimensional quality. I really like the valhalla's but really struggle with the cost when compaired to the rest of the system. Anyone compare the Tyr and Valhalla that could comment on my observations?
