op
the cary slp98 should not sound harsh in the treble - it is either the tubes themselves or the isolation of the unit... the slp98 is suuuuuper smooooooth
make sure you have tube dampers and the unit well isolated
maybe you want to try a new preamp/linestage but i don't think you have gotten the slp working at its best yet... my 2 cents (i used to have one ran it for 2 years very happily)
