i have 2 pairs of b&w’s: 686( 2005 bookshelves)and dm 580 (90’s floorstanding) and tried them at home with arcam delta 60 integrated ,arcam delta 120 power amp (with some ss and tube preamps),nad c352 (given as a present to a friend), an old rotel receiver (traded for a wireworld rca cable)and a jvc receiver(given as a present to another friend). arcam and b&w always work the best since arcam is warm and realistic so it’s never dull (b&W and nad or jvc)or too bright (b&w and rotel)which are the dangers with b&w speakers .
