I have high frequency hearing loss but can still tell when highs are not smooth, and it seems to be the actual recording that makes my 703's harsh sometimes. I got some coarse black cotton mesh and lined the metal mesh tweeter caps with it and it helps the offending program material, although most of my listening is done with the protector caps off altogether. I use Audionote silver I/C cables throughout (AN-V and Sogon 50), and a double run of Vintage Polk Audio Cobra cable to the 703s with the brass jumpers in place(not biwired). My electronics are Simaudio Moon Evolution Series I7 integrated amp and and CD player, and a Dynavector Karat 17D3 MC cartridge on my Pro-Ject 2 experience. Phono stage is Simaudio Moon also.
