With Nordost your system must be on the certain level and you have to take time to evaluate these cables. I’ve tried Heimdal 2 and Frey 2. Frey 2 was better. But they didn’t wow me. The Tyr 2 is just next level in SQ. I’m running Tyr 2 XLRs now and this is the best my system ever sounded. There’s also a surprising synergy between the Tyr 2 interconnects and the Audience AU24SX speaker cables that I currently use.
Will most likely give the Tyr 2 speaker cables a try soon to see what they have to offer over Audience.
So the sweet spot in the Nordost line up is what sounds best to you in your system within your budget.
