I’m guessing I’m not going to be much help, but you do have me wondering. I have the PA3100 HV, but upgraded all my cables - and my distributor to Nordost at one time after auditioning things piecemeal. But I never tried the upgraded cable on just the amp alone going straight into the wall. I run everything through the Nordost QB8 mk III (which is not a conditioner per se, but noise reducing distributor) and have Valhalla 2 and Odin 1 power cords.
I liked the Nordost better than audioquest though I did not audition all the way up to the dragons which i probably should have. In any case, the upper level Nordost seem a nice match for this amp. I don’t think I’d put anything less than Tyr IIs on it.
Clearly, an audition will be a must for you and I’ll be curious as to what you find out.
