Hello Larry,I was going to refrain from making any comments for a couple hundred hours,,,,,but i must admit im dying to talk,,the first few hours it sounded nice,but nothing special,sort of closed in,after around 8 hours i could hear it opening up,better focus,tighter,im still trying to decide which gain setting i prefer,right now i seem to prefer 1 notch down from the highest setting,still playing with it,my unit did not come with a power cord ,im using Signal Cable Magic power cord now,i will update as things progress,thanks
