olds1959special Posted April 18 Share Posted April 18 (edited) I’ve been through about 6-7 amps recently and in the process discovered horizontal bi-amping. At this point I’ve settled on two amps: a Hafler DH-120 for the midrange / treble and a Rotel RB-1050 for the bass. No more class D amps, they are possibly okay for bass but since I got the Rotel I have no need to change anything. The seller said he biased the Rotel amp to factory spec. I did have to attenuate the level with the volume trims. I did this by ear as I couldn’t think of a better way, just listening to music and adjusting as needed. I thought of playing pink noise and measuring but figured using my ears would be better? Edited April 18 by olds1959special Link to comment Share on other sites More sharing options...
