I went from a stock sony 777, supposedly the same sonically as a SCD-1, to a modded SCD-1: superclock 3, black gates, vishays, so definitely an older mod than you're looking at.
that being said, what I noticed in the switch was more 'delicacy', humanity, analog-ness - not more whizz-bang or pounding bass. to my ears it was a definite improvement.
given the age of the SCD-1, the expense of mods, the expense of (future) repairs on the SCD-1 (assuming you can get parts), I wouldn't do it if I were you. I'd spend the money on a great DAC (SCD-1's are considered great transports) and when the SCD dies on you, either go HD or get another CDP to use as a transport. the only downside is if you have lots of SACDs (which won't play through a DAC).
incidentally, the guy at RAM told me that a fully modded oppo 83se (the unmodded version was $500) will beat a SCD-1 with the best ($$$!) mods he has.
