Luxman L-550 AX Mark II on low volume (apartment)?

Hey all,

Been eyeing an Luxman L-550 AX Mark II for quite some time that I might get to buy for a reasonable price. Living in an apartment and listening seldom on high volumes. My current PrimaLuna works indeed well on lower volumes as well but what about Luxman L-550 AX Mark II?

Anyone auditioned this particular amp on low volumes? 

Read that some other, more expensive Luxman's need some volume for it to shine.

Will drive Harbeth C7ES3 40AE.

Thanks
