This unit is what I have been looking for!!!!Simple with ease of use..Four stars due to the fact that they designed it without an On/Off switch???Works great!!!Gain control is very sensitive with smooth movement..Monitor output very nice, can be cranked with no distortion..My archive of LP's has been saved from the big bad dust bunny's..This unit works nicely with Adobe Audition and (Diamond Cut)Restoration software from Tracer Technologies .For those on a budget,Cost was a bit of a budget buster, but this fun little box is worth it..
