***What Cables For McIntosh***

I have 2 McIntosh systems and use Groneberg Quattro Reference speaker  cables and interconnects.  I use all Shunyata power cords.

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

Sorry ,phone cut me off...again in my opinion if staying with Harbeths id go with something that had better bass control.Im not a Harbeth fan at all so grain of salt speaking ..Not a fan of Nordist either especially with that speaker line,much better choices out there for probably less money...just my opinion
