I also have Pike's Peak and have been looking to upgrade higher in the AQ lineup. In lookng at the Mount Blanc, the only difference that I can tell from Pike's Peak is the use of only PSC+ in MB and a mixture of PSC and PSC+ in Pikes Peak. So, technically they are better - doubtful if you can hear the difference. It seems more logical that a real upgrade, if you want to stay in their copper cables is Volcano - which is all PSC+ as well as 16 strands of wire vs only 10 strands in either Pike's Peak or Mount Blanc.
