You won't believe this! But it's true. The problem is most likely the interconnects between the TT and the phono preamp!
Really.
I sell interconnects under my brand name BEAR Labs, so I do have an interest in this issue. Many times, I've demo'd the complete transformation of the "sibilance" from Lp to clear highs by merely switching in one of my interconnects and making no other changes.
The sibilance problem with Lp bothered me for many, many years, and I never found an adequate explanation. Then virtually by accident in the course of routinely changing out my interconnects when I first developed Silver Lightning I was really shocked to hear a lack of sibilance, and the appearance of nice smooth clear highs! I reproduced the improved sound at every audiophile's house I could find and was completely convinced, but surprised.
I still don't know exactly what the cause is, but there it is.
