Hi Gherrera1
Sorry for the late response for I just saw the question. I would say again the Heimdall is probably the best value. Tonality I think they sound the same BUT there is just 1/2 hair more air between the vocals and instruments with the Frey's. I really think I could have lived with the Heimdall's and knowing I saved $1,000 would be nice. I had the opportunity to have a Nordost dealer demo case for 6 weeks. Personally I thought the Blue havens and Red dawns were too bright but good considering the price. The Baldur seemed to tame the brightness. The Heimdall and Frey took it to another level for me. Improving on the mids and high end. I think it is the micro monofiliment technology. 85% of the wire is suspended in air. Seems to bring out more separation/air between the vocals and instruments. With the dual monofiliment 90% of the wire is suspended in air. The Spm is more like a Baldur construction but more toward the Vahalla wires. I never heard those.
Reviews state the Frey is 90% of the Vahalla but I would say the Heimdalls are 88.5% in my opinion. Again you do have to really 'squint' to hear the differences. Since I bought my cables new from a dealer they are getting my 1st year re-burn in from the Vidar. I hope to get them back soon because I am using a demo pair. I'll be real curious to hear any differences. That was 1 reason I bought new is my dealer gives me yearly burn in service.
These are just my opinions and to give you my system it is Meridian G08 cdp with a Bryston B100 int amp and Dynaudio C1 speakers w/Rel B3 sub. Interconnects and power cords are Fusion Audio.
Hope it helps and good luck whatever you decide.
