Do Nordost match with B&W

The dealer here have almost everything like Transparent, Taralab, MIT.... but i cant borrow. That's my problem

Your friend's description on Nordost sound coincides with my thoughts. I have not tried Heimdall but I have owned the higher-end Nordost Frey XLR interconnect. If you want more dynamics and better bass, consider the XLO Signature 2. The bass on the XLO kills the Nordost. If you want slightly warmer sound but still have good dynamics and bass you can also try Acoustic Zen Silver Reference 2. Haven't heard the Transparent before so can't comment. Good luck in choosing your cable.

Can you compare the cables in the hifi store? I you can't borrow the cables, then I think that would be the best idea.
Good luck in your cable search. Cables can be a pretty big jungle.

It's really a big jungle. So many out there. It makes me confuse .Thanks for sharing your experiences. I think i will try Transparent but which one is good??? i don't know much about Transparent product line.

Ngocdj,
Transparent just came with their new MM2 upgrade of all their cables. I readed in TAS that it's a big sonic upgrade, so if you buy a Transparent cable, bee sure it's the newest line.
All Transparent cables have the same sonic character, so try the one you can afford. It just get better, when you go up their product line.
Good luck! I am sure you will like them.
