I am especially interested in reactions concerning soundstage, midrange and bass response. It’s in those areas where several users have found the J2 to be somewhat lacking.

I’m hoping that with the right speakers that the J2 will be the amp for me.

But please give both positive and negative experiences with any of these speakers when paired with the J2 amp-and when played at low to moderate volume in an average sized living room.
