Wyred 4 Sound STP-SE preamp

Wyred 4 sound stp se DSC_0128 STP-SE-rear

The STP-SE preamp offers a minimalist look but with a function display screen.
It comes in 3 flavors (and two color choices: black & silver):
Stage 1 upgrade
Stage 2 upgrade which gets things out of the affordable or reasonable range for preamps in my opinion, but as always, it’s an option. The Stage 2 upgrade as you see offers a green OLED display, but don’t be confused thinking that you must choose the upgrade to get a display. It’s just an optional color or type preference, the standard edition comes with a display (see list of features). For more info, see link below:
