Something i had posted on another forum sometime ago>>>>
OK, its really simple! All the amps are basically PSA-2,s!
The letters only indicate extra options.
1. SA-2. Consumer hi fi version with RCA inputs, ladder led display, and milled aluminum knobs.
2. PSA-2. The amp. 1/4in inputs, no bal input module.
3. PSA-2X. Amp with balanced input module.
4. PSA-2DX. Amp with both balanced input module and ladder led display.
They all say PSA-2, and if they have the options you will be able to see them.
