Valkyrja speaker cable versis valhalla

Okay I am curious if anyone has heard these two cables in their system and compared them.

I currently have a valhalla interconnect between my amp and cd player.

I have the emmlabs digital cable between the dac and cdsd.

I own Wilson 7.0 puppy speakers and rowland 302 amp.

I am currently still using my old nordost red dawn version one speaker cables.

I feel my system is pretty sweet but as an audiophile I wonder whether upgrading the cable from the red dawn would make a palpable difference. I am loath to spend even more money and not hear a difference since the system is already pretty cherry.

Anyway I love the advice I have gotten on the audiogon over the years so fire away

thanks

Mike
