Consonance 6550 tube question
Changed from a sold state McIntosh to a 6550 based Consonance integrated (Cyber Series). The loss of deep bass extension is something I would like to improve. Will switching out the stock tubes in the input and or output improve the deep bass performance without giving up any of the midrange and treble that I have come to love. Speakers are vr4 JR in a larger room. Any one with experience with this amp please offer suggestions. Phil Brady. T
