Nordost Frey interconnect hum


I bought a pair of used Nordost Frey unbalanced interconnects here and i noticed they induce a hum through my speakers when my preamp is off or when the cables are only plugged into the power amp. The strange thing to me is that my Nordost Heimdall interconnects do not induce the hum under the same conditions nor do other shielded interconnects. They do the same thing on another system as well. I understand that both the Heimdall and Frey have the same 97% shielding and the only difference is 2 extra center conductors. I'm waiting for the seller to ask Nordost but i thought i would ask here if anyone can explain it.

Thanks for any advice.

I see you use Arel sub. Those sub's I sold a lot in gthe past. Now I would give a negative advice. The reason is very simple. Tooooooo slow and downfiring has nothing to do with highend audio and becomming one with the rest. I have done a lot of tests with many subwoofers. Now it is for me very easy what is good and not. I always had expensive highend systems with big speakers without sub's.
Because subwoofer were to slow I always was listening to flaws, this I really hate. But the Monitor Audio PLW-15 made me think differently about sub's. I also did some teste witht the most expensive Velodyne sub's. Still too slow like the Rel sub's. Wenn you use a subwoofer which is closed and has a big unit (15 inch) in front you can get stealth quality. The respons of the Monitor Audio is superior to Velodyne and Rel cause of the respons. The material they are using is lighter and that is why the speed is higher. They use a very big magnet and it is extreemly tight. The control is awesome so i can easily use it to 120 hz. Rel using above 60 hz and you get shit. Not enough speed and not enough control. For the first time in life I heard a sub can become one with speakers. Because of the use of 120hz the focus of voices and instruments increase dramaticly. Buy Jacintha is her name. Track 6, the contrabass is on the left side of the recording. With the PLW-15 the focus and dimension stays the same without the sub. The instrument is even sharper focussed. Withe Rel and Velodyne we did the same test. All the test the contrabass became too big in dimension. And the speed was not accurate. We did not get the feeling of stealth quallity we are ys aiming for. My clients call my sub voodoo. They all say: This is the first time in life a subwoofer is becomming one with the speakers. Many of them play with expensive highend systems.
The low freq. was the part I did not like of the Frey. Wenn you go one level higher, you will much better low end.
Daveyf - I never had the chance to listen to the original Tyr's. The only 2 Nordost cables I never heard were original Tyr's and Odin. Also I never heard the Leif series either. So you could be right. My reference at the time were my original Frey's. The series2 are very different. I will admit the Tyr2 ic kicked the Frey2's butt!! That being said the Frey2 is much better than the original. Speaker cables included. My favorite combo was the Frey2 ic and Tyr2 sc. My sc's are 4 meter and Tyr2's were way to far out of my budget.
Bo 1972, Wenn you use a REL sub, you have to make sure that it is dialed in
correctly; that way when you listen to it, it will blend into the mix...;0)
Bo1972 - Funny my first real ic purchase were the AQ vipers. I liked them a lot but there was no emotion (blurry - flat sounding and no 'air' between the instruments and vocals) to the music. Good low to high frequency response. Later I got the Cardas Neutral reference. More emotion in the mids but rolled off highs and lows. Next were the AQ King Cobra's. Another good one for frequency response but only a hair more emotion than the Vipers but not as good as the Cardas. Then the Fusion Audio Interlockers. Great frequency response and more emotion and focus than the Cardas but had a narrower sound stage. Then the original Frey ic. Great emotion - best 'air' between the instruments and vocals and a wider sound stage. These also had the best focus. I will agree the Frey's didn't have the best low end frequency response. But it didn't matter because I have a Rel B3 sub. So the low frequency was a moot point. If you have the opportunity listen the the Norse series demo case. The lows are there with these cables. Speaking of the sub the Rel B series is a great line up. But when I tossed the original Rel cable and had a Nordost Bassline made to Rel spec holy cow what a difference. Attack and decay like I never knew existed in my system.

For what ever it is worth I started with a Rel B3 and Bryston B100sst integrated and upgraded to an Octave V70SE tube integrated. Dynaudio C1's and upgraded to the C1 Signature. Started with and still have a Meridian G08 for a source. Added a Purepower 1050 regenerator to my dedicated lines.

That being said I always recommend AQ cables for beginners as a good entry level bang for the buck cable. System synergy will determine whether or not AQ - Nordost etc are right for your system. For me as I upgraded my system cables made more of a profound difference. Prior to that they made a difference but not as profound. Last when I audition cables I disconnect the sub.

That's my experience
