Build by the one and only "SWA"
This is a Fully Balanced Dual Mono Sigma 22 Analog pre amp in separate enclosures with a Gold Point Attenuator.
This pre amp will compete with some of the more costly active pre amps out there. It served me very well paired with my First Watt F1J and HE-6.
It replaced all of my digital pre amps that I was using in my DACS ie PWD mk2, NAD M51. This analog pre amp with it's "Gold Point Attenuator" did a far better job.
