I took speakers for the Yamaha rx-v1067 receiver as fronts to replace the old wharfedale diamond 8.3. The sound difference is amazing. Depth appeared, the bass became denser (I practically don’t turn on the sub), although some redundancy of high frequencies appeared (there were more hissing overtones in the voices, but the strings sound excellent), perhaps the receiver’s sound transmission features or the use of a silver-plated cable are to blame, or maybe they haven’t warmed up yet.
