Designed and built back when Stan and Paul were together at PS Audio, their designs are noted for exceptional phono sections. This model has variable cartridge loading and gain so dialing in the settings for your MM or MC cartridge is easy. The variable gain feature allows you to set just enough gain for your needs and thus keeps the noise to a minimum. Also has straight-wire mode past the input selector to turn it into a line-level passive preamp. PS Audio pioneered the use of massive, oversized power supplies to provide unlimited current for excellent transients and tight base.
