James,

Would you highlight the hardware and software modifications that occurred throughout the 7B-SST lifespan (between ST and SST2).

Are there any upgrades on these older monoblocks from the factory? 

If possible include serial numbers when the changes occurred.

Thanks, JohnnyB

Hi Johnny,

We did not change much of signifigance in the ST Series during their life span - there was a big change with the SST and then more signiificant changes with the SST2 on most models.

We do not have any upgrades from the ST to the SST or the SST2 because the changes do not warrant the costs.  It is more cost effective to resell the older model and take that money and use it on a more rescent version of the amps.
