Is it worth to get 2 m Nodorst vs 1m

I am not a technically inclined audiophile.  I am a listener who doesn't want to "squint his ears' to hear an improvement in my stereo.  As I said, it's been many years since a purchase.  My interconnects have broken, I've lost my Krell amp to repair for the umpteenth time and I contacted Nordost about some interconnects to consider and their response was that a power cord made more of a difference than the interconnects.  When I tried the cords, Tyr and Frey 2's, I was flabbergasted at the difference they made ( yes the prices are stupid high) but the sound improvement was equivalent to a component change.  I have Valhalla 1 as my speaker cables and a Valhalla 1 power cable feeding the system from the wall to the Qbase.  I was amazed at the difference the Tyr made when I replaced the stock cord on my Krell KCT pre-amp.  The dynamics, imaging etc. just exploded to an open engaging sound.  This was surpassed when I combined the Frey with my old PS Audio DAC...it got way better.  I have a Rotel amp that is the very weak link in my system (i bought it because the Krell will be gone for months in order to play my Theil CS6 speakers.)  I tried a Heimdall on the amp with the other two and didn't notice a further change.  My Krell has a captive cord so unless i finally change that, I will buy only two cords.  A  dealer i spoke with felt that these cords make the biggest difference on lower current components like cd players, pre-amps and Dac's.  I have to say that while I feel dumb paying these prices, when you get an effect so captivating it's hard to ignore it because of price.

@urbie  Are you going to post the same comment on every power cord thread? Have you personally done the comparisons against the specific power cords that you denigrate? Offer up more than what appears to constitute a sales pitch.

 Facten,

actually I have and obviously you haven't done your research and it's not a sales pitch it's a fact ofc copper is inferior to OCC single Crystal copper and you can ask anybody on here that knows anything and they'll tell you the same thing,OFC copper has 400 Crystal barriers per foot they're little fractures in The wire and the signal has to jump through those little fractures and it causes the sound to be hard, bright cold, edgy, any one of those things are all of those things together, OCC single Crystal copper has zero Crystal barriers in 700 ft so you get a much more natural open three-dimensional sound from OCC wire, companies like transparent and MIT that rip people off when they're using cheap ofc junk wire and charging $40,000 for a speaker wire is a rip off as far as I'm concerned and anyone that pays $43,000 for a piece of wire should have their head examined, and just so you know there's now something even better than round OCC single crystal wire and that's rectangular OCC single crystal wire which outperforms the round OCC, I've been at this for 40 years and I've tried all kinds of cables that's how I know that OCC single crystal is far superior to anything ofc on the market and just so you know my system is worth $70,000.

@bossa 

Out of curiosity, I'm wondering if you have had an opportunity to audition any other power cords in your system. I ask because when reading your original question it sounds as if you have not experimented with other power cords.

I'm not saying that Nordost power cords aren't good, but what I'm wondering is if a different less expensive power cord ($500 or less) would accomplish your same goals. If you wanted to share your location perhaps someone in your area would be willing to lend you a few after-market power cords.

Sorry @urbie but what type of wire is only part of how a cable sounds so when you say "OCC single crystal is far superior to anything...." I don't agree. Have you heard the Furutech Project V1 cable? I've heard nothing close this after 40+ yrs of hearing many, many different power cords. Once heard there is no going back to anything else IMHO
