Due to upgrading to a fully modified Tact S2150, one of my other stock 2150s is for sale (either one but not both).
The S2150 is an amp, preamp and DAC all rolled into one -- just add a digital or analog source.
Originally sold for $4400 but now discounted with the new 'x' model.
One is older (same unit, though) and has a slight mod: an upgraded Aberdeen Ultra High Speed Bridge Diode with Vishay Smoothing Capacitor. Takes digital input only. I'm second owner.
$1350 for this one.
One is newer (I'm original owner) and has the $570 analog input board. No mods. Takes both analog and digital inputs.
This one is $1575.
