Tyr 2 vs Valhalla v2

Hi guys 

im on the edge on getting myself n upgrade on loudspeaker cables and power cables. 

Current setup: devialet 250, b&w 800 diamond 2*velodyne dd15+

I have been auiditing frey 2 and tyr 2 loudspeaker cables. 
They both are another world upgrade from blue heaven which i already have. 
The Main differense between the tyr 2 and frey 2 are that the tyr 2 are more punchy in the bass on my setup. If the price difference between tyr and frey is worth IT is discussable. 

The thing i Wonder, how would the Valhalla v2 stand againt tyr 2 (and frey2) loudspeaker cables.

is there anyone out there tested this? My dealer dont have the Valhalla v2 for auditioning.

if anyone have any experience with the powercables frey2, tyr2 and Valhalla v2. Feel Free comment the experiences:)
