Ive never had any of your gear in one system so this is really irrelevant but i have owned mac gear over the years mc402/452,mc60s,275,240 few others,never heard the 30.1 but owned the 40.1 Harbeth for a very short time and several Nordost cables up to Valhalla..I cant imagine any of this sounding that great all together in one system.Ibdid habe the harbeths mated with the mac 402 and it sucked imo..way too much politeness if you will
