Break in time for Nordost Valhalla


I own a pair of Nordost Valhalla interconnects and after several days of break in, I'm noticing little or no difference in their sonic characteristics. The mid to top end is still brittle and edgy. Is it 50, 100, 300, how much time before the cables settle down. I've read and heard for several years the merits of Nordost. I want to experience it. Any owners of Vahalla wire, give me your feedback.

i have owned Valhalla since 2001; and at one point used 6 sets of Valhalla interconnects in my system. i now have three sets.

i purchased a Nordost CBID1 (Cable break-in device) when i first purchased my Valhalla and have always used that for break-in and annual 'tweaking'.

i would expect that it will likely take 300 to 500 hours to optimize the Valhalla. if you own a good break-in disc with 'ultra-sonic' type noise that would be best to use some of the time.

there will likely be some that will respond here that Valhalla is 'brittle and edgy' after break-in. not true. Valhalla will not 'smooth' or 'soften' the sound. but it will tell you what is happening in your system; whether you like it of not.

BTW, if you purchased your Valhalla from an authorized Nordost dealer they should have the latest Nordost break-in device, the Vidar, and should offer to break-in your Valhalla as a no-charge customer service.

another caveat; if you purchased your Valhalla privately, and it has no serial number or wooden presentation box, it could be that it was 'cut-down' from a longer length and does not have the proper factory termination. this could be the source of your edgyness; the Valhalla needs to be properly terminated.
I have but one short length of Valhalla used in my V.P.I. tonearm. As Mike Lavigne points out it takes an extraordinary long burn in needed to hear the true measure of what this wire can do in a system...Carrying on with more Nordost wire to my phono stage was a striking revelation.I realized at that moment the enormous sonic benifits of this wire used in a tonearm.Harry Pearson of the Absolute Sound and Roy Gregory of Hi-Fi+ magazine report no anomolies produced by Valhalla.For those of you that hear other wise....its not the wire....
