What are the differences between a STAX SRD-7 Pro and SRD-7/MKII?

Basically the SRD-7 Pro has two Pro outputs, whereas the SRD-7/Mk2 has one Pro bias and one Normal bias output, allowing you to use both normal and pro bias phones.

Hope this helps.

Apart from the different outputs (details above), there are external color differences as well.
The SRD-7 Pro are all-black, while the SRD-7MK2 have silver (aluminum) front plate.

Here are the three different SRD-7 models (no SB units).

How about the SRD-7 SB?

Self-biasing -> No wallwart needed

As far as I know, the Mk2 is the best model because it has upgraded components to the other ones.

Two Normal bias output.
SB = Self Bias. Meaning that it take bias voltage from the speaker level input, instead of the regular mains power (wall plug)
