The rumour is that Plinius lowered the treble down a bit for the SA-102 and 250 MkIV versions because that's the way they interpreted customer demand. For the 103 and SA-Ref, it's back up. Again, just a rumour, read from a review.
Don't know of any factory upgrades but you can ask Plinius.
Try silver blend IC's/ speaker cables. Maybe Nordost. Maybe Ultimate Cables. Hard to go wrong on the latter, for the price.
