I second other poster’s comment on cables, without knowing what cables you are using, power, interconnect and speaker, no one can tell you why things are off. Another high probability is speaker placement in the room and toe in, it’s very likely you have placed the speakers in the right spot for the bass to couple to your room, therefore tonal balance is off
Warm Tube Amp(s) to Tame Hyper-Accurate Speakers?
I have these Spendor D9.2's mated to an MC275 VI and the mids and highs are still too much, sometimes. Sometimes the sound is sublime based on the recording, sometimes harsh. I imagine perhaps Focal and B&W folks know what I speak of, maybe not Magico owners. Even using a C2700 tube pre-amp. Can this be solved with a WARM tube amp, and if so, which ones? I like my MC275 VI but I am open to suggestions.
