my amp is a BHK 250 and my speakers verity audio parsifal ovation. They match perfectly to my taste.
My speaker cables are DIY made of 3 runs (actually 3 runs red and 3 run black) of neotech occ bulk cables of 3 different gauge, in order to both reach a small impedance (I have long runs) and to address the possible skin effect in the highs.
My speaker shave mono amplification connections. So far I connected together the 3 cable runs at the speaker side and at the amp side as well, using only one of the speaker outputs available at the amp back. Yesterday I tried to separate the cables at the amp side. The cable with the bigger section plugged at the lower plug of the amp, the two other cables at the upper plug of the amp.
I expected no change in the sound restitution but there was noticable changes:
- stereo image much more focused at the center
- smoother and maybe cleaner high mids
- more bass (between 50-100Hz I think), two much actually, because it hides the lower bass
Can some of you explain this difference?
From a pure technical point of view, what should be the best : all my cables connected to a single speaker output, or split and connected to the two speaker ouputs?
