Options, buy and add when needed.
Anyone own this model? How does it compare in sound performance etc to the Macs?

"The 9B SST2 is a modular, single-chassis power amplifier delivering 140 Watts per channel into 8 Ohms. That word 'modular' is critically important here. Like other models in the SST2 series, the 9B employs modular construction in which each channel is self contained with audio circuitry, connectors, and an independent power supply. However, the 9B channel module differs in that it is built on its own removable assembly. This means that not only may any channel be easily swapped in the unlikely event of failure, but also that the 9B may be configured with fewer channels if an application so requires.
Indeed, the 9B SST2 may be ordered in a 3, 4 or 5 channel version. Modular channels are available separately for later expansion."
