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.

Xti16, I too have the Frey sc's and am also using Tyr ic's. I think this is a great combo.
Daveyf - Have you had a chance to demo the new series2? I was quite happy with all original Frey's. Then I heard the series2. All I can say is Wow.
Xti16, I have heard the Frey 2 ic's but not the speaker cables. I think the Tyr ic's are still superior to the Frey 2 ic's. Happy with my Frey sc's...for now:0)
Valhalla gives a lot of resolution ( details) but Audioquest sets everything better in place. I call this individual focus. During listening it is a lot more easy to focus on only one part of the recording. Wenn you go back to Valhalla it is less focussed. Like a photo what is less sharp. That is why you need interconnects to give it a more sharp focus. It is the same wenn I listen to Avalon. I see a big and wide stage but the individual focus is less sharp. I know that in real instruments and voices are very small in dimension and often very sharp focussed. The Audioquest make the stage wider and deeper.
2nd and 3th voices on recordings are so much more easy to pint out were they are standing during listening. They are louder and a lot more easy to follow. Wenn I had full Valhalla at home I missed emotion in the whole sound. My smile on my face was gone. Wenn the focus is very sharp you turn a lot with year head during listening. That is how sharp it is. Going back to Valhalla I didn't do this anymore. There is a lot of details, more difficult werer it is comming from. The Audioquest gives more realism is sound of instruments and the overwhole sound has more authority. Liken you use a more powerful amplifier. I want to play very deep, very wide and like now many recordings some instruments play in front of you. I am a perfectionist, I want everything what is possible in sound. Deep and wide is even not enough. Within this big square stage the focus of instruments and voices need to be point out exactly were they are standing. I do not do it for less.
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.
