On a side note, FirstWatt has a new model out.
"The F8 revisits their most popular J2 model but simplifies the front end for just three signal-path devices per channel. It applies current not voltage feedback and improves on the J2 specs on bandwidth and damping factor."

The output impedance is 0.2 ohms, which puts it between the SIT3 and the J2, but far below the SIT1 and SIT2 at 4 ohms.

The Brinkmann Integrated amp is a great match with single driver speakers

@debjit_g  I am using cables made by Scott Sheaffer. They replaced my Synergistic Research cables (which were also quite good).
