Is it worth to get 2 m Nodorst vs 1m

I have the opportunity to buy a couple of Nordost power cords, Tyr and Frey at a 15 discount. I auditioned the cords in a one meter length and they made a nice improvement. The dealer quotes NOrdost as saying, it will sound better in a 2 meter. I have a dedicated circuit for my Qbase strip which has the whole stereo plugged in. I thought i read somewhere that a dedicated circuit makes the longer length improvement questionable. Adding another meter to both increases cost by about 1000. They already cost close to 5,000 so this would be closer to 6,000.   I can’t test any of this. I just have to make a decision. Would like your thoughts. Thanks.
