Greg,
I would also be curious as to those that went from STs with the dome tweeter to the SCSTs. I have the STs with the dome tweeter and have also considered going to the SCSTs. I think the differences will be a bit more resolution (accuracy?) with the Raal tweeter and much better bass response. It is a tough time to sell audio gear I believe. The other factor with Salk speakers is some would rather pay for new speakers to be able to chose the finish they want.
