Dear friends have just set up their first high end system. They have paired these Sonus Fabers with a McIntosh MA9000 and their source is high res Deezer through the Wyred4sound modified Sonos connect.
The immediate presentation is extremely fatiguing on the high end. Unlistenable at moderate volumes. Both of them are experiencing the same clouding of their eardrums. Unfortunately they are on the west coast and I cannot visit to hear myself.

How profound is the break in for these speakers?

Do these speakers need a tube amp or preamp?

Is the MA9000’s 300 watts going to hold them back?

Please help me head off this tragic first high end system experience!
