PENON OS133

the OS133 is an improvement in accessible natural sound by altering the sound to becoming slightly clearer and spacious. You can kind-of hear more into the stage, like the instruments have become spread apart in both right to left and subtly front to back. Though after time much of those contrasts go away as you adapt and take the sound for granted, the next level is instrument filagree. Meaning due to clarity there are ever so slightly different details which can emerge, which go and show simply that there is more definition to the signal.
