I’ve owned/used -
BH: PCs, ICs
RD: PCs, SCs
Frey’s: ICs
SPMs: (Nordost Reference level from 2000-2005) XLR ICs, and BiWire SCs
It would be good to know what amp you are using, and what ICs you are using (also Nordost?)
but not knowing the amp/ICs, for the NHTs, I would suggest BH or RD.
(I have a pair of RD speaker cables available, I bought them new, 1 owner. Email if interested).
