@Tail That's what I was thinking. I'm going to order a a moon audio balanced cable for the SE846's. Taking a different direction. I am wanting to use my AK240 to power one or two floor 3-way speakers for a small 10x13 room. I plan on using a the 3.5mm optical out into a digital to analog converter that support 192/24. Any suggestions on speakers or would I need an amp here. I'm figuring I would to drive them.
Can't give any suggestions there since I don't know honestly, never tried to play with that, and returned AK120 pretty fast :/ But quite sure that you don't need any for those phones you mentioned.
