That’s where it started for me - Tyr II interconnects (xlr balanced). I auditioned them against what I had (Cardas something), Transparent and AudioQuest. The Nordost - in my system with my gear at the time - was noticeably better than the others at the same price point.
Those are very good interconnects and the difference they made in my system was significant - and much for the better. I did end up upgrading to Valhalla 2s. Better again but not as much difference as the Tyr II made for me initially.
Then I fell into the rabbit hole w/ Nordost power cables and QB 8.
Full disclosure - despite my comment on the benefits of an all Nordost loom (a comment I stand by as I heard it w/ some disbelief), I do have a few non-Nordost cables in system still. But, I’ve changed too many other things recently (upgraded my amp, speakers and DAC all in the past 7 months) and I want to be careful here as things are still being revealed.
I found the Tyr IC to be the most beneficial change so I think you’re starting from a good place. The Tyr speaker cables are significantly more $$$ than Frey so it’s worth treading cautiously around that rabbit hole.
Best,
