opinions on Nordost PC

Make it yourself more easy, compare a Purist Audio powercord with a Nordost powercord.

You will also find out how much deeper the Purist can go in the lowest freq. Beside this the individual focus of instruments and voices is much sharper.

Audio is always about those products who are the best. Powercables is a totally different world than interconnects and loudspeakercables.

Different rules but they can make a huge difference in sound quality.

I have a Heimdall 2, and heard a Frey 2 (power cord). Heimdall won, but here's the twist: the dealer had not broken in the Frey 2 very much. I don't care what Nordost or anyone else says: these things take WEEKS to break in, 24/7. I've owned EVERY iteration of power cords: Shiva, Vishnu, Brahma, Valhalla, (series 1) and then Heimdall, Tyr and Frey 2 (interconnects) and they ALL take almost exactly 3 weeks to break in. Anything less than that period and you're just not hearing them. And it's fine to choose someone else's cord/interconnect or whatever. Just make sure whatever you're listening to, the dealer has played it steadily for a month. I think many of us are disappointed in things that aren't fully broken in. I heard my Hurricanes in 2003 at Lyric and sat thru the audition, but walked out thinking, they've GOT to be better than this. Harry swore by them. So I ordered a pair - elsewhere - and cold, out of the box - but on speakers and cable that were used, they sounded otherworldly good. So, don't go by what you hear in the store. That was 13 years ago, and I don't have much faith in dealers anymore. Well, some of them. They are so lazy, and as one said, "Are you kidding? We change equipment so often, it would take forever to break them in." And I thought, that's why your Sasha setup sounds so bland (with the latest ARC electronics driving them. No nuance, no inflections. Impressive to a novice, maybe. Not impressive to an experienced listener at all).
Concerning break-in (or lack of it), you'll either be sold  on a component - or come out a skeptic.

Sorry for the late return on this but I had a slight switch around in I/C and P/Cs, here are my findings on the Tyr 2 powercord. The Tyr 2 powercord took ages to run in, and I mean weeks. It took so long that I was beginning to think I had been sent a dodgy cord. Even after break in it took another couple weeks to settle down. But , thankfully it was more than worth it. The bass can only be described as grand. Much better than my experience with the Valhalla. Deeper than I was expecting but also tight without overhang. Much more reproduction in both lower and mid feeling.
The midrange is very fluid and as detailed as the Valhalla but without the hardened edges.Detail is portrayed in a deeper soundstage , back and forth and left to right, unlike the Valhalla which I felt tended to disjoint the music the Tyr2 keeps the music together as a flowing believeable piece.
The treble is extremely good , not like the nose bleeding retrieval the Valhalla induced. Again I blame the hardened edges I found the Valhalla gave way. This is the most transparent powercord I have had the pleasure of using. Nothing in the freq range appears veiled or dampened.
As the cable settled I was fortunate to have the cash available to upgrade my interconnect from the Graditech Kide 3 to Wireworlds Platinum Eclipse 7.
A truly startling experience. With the Graditech I loved the sound of my system with the Tyr2 in place . With the top line wireworld I am in awe of what the system can reproduce. I believe I can now hear the true benefits the Tyr2 brings to the system
I am shocked at how few Tyr 2 users there are out there. I have no regrets Purchasing the Valhalla as it was my dream P/C to try. In all respects the Tyr2 is an improvement on Valhalla 1 ( in my system ). I can now listen to music for hours and relax doing so.
The best compliment I can give the Nordost Tyr2 is this. You hear everything in a liquid presentation , nothing stands out and shouts , it does everyting extremely well.

Dear Bo1972, which purist series you suggest for tube power amp?
Thanks.
