You might want to read a review of the AG 2s I did back in 2005 for ultraaudio, a webzine.
I owned, simultaneously, the Alpha Core and the Valhalla (both interconnect and speaker cables) and found them nearly (not completely) indistinguishable.
Interestingly enough, back around 1998 or maybe a bit later, TAS also had a review of the Divinity line, and found them superior to the Nordost. Roman Zacjew wrote the review. HP later commented on them, and was surprised to hear that they were nearly indistinguishable - but later on, he used a turntable and found the differences more pronounced.
