I have reviewed the Bryston Website and am unsure of the difference between the 14BSST and the professional series, can someone shed some light?   

The one difference that I was able to determine is the ability to get the 14BSST pro in a 240v configuration, any others?

The  Pro series is available in Black 19 inch rack mount faceplate only.

The consumer C- Series is available with the C-Series cosmetics - in silver or black and in 19 inch faceplate or 17 inch faceplate.

The Pro series also has volume controls in the circuit path on each channel - the consumer C-Series does not.
 
I usually recommend the C-Series if you want the simplest cleanest signal path and the Pro if you need the volume control on each channel.

Both Consumer and Pro are available in 240 Volt.
