Fantastic little amp with a good amount of power. Recommended by Abyss for the pairing with the Diana TC. Comes with the power adapter and original LG batteries. I swapped to Panasonic 18650B when trying more sound options out of it. I am only selling this because I have two of them now and only need to keep one. I purchased this second hand about a year ago and listen to it all the time. Typically I listen to it with fully on batteries and its still amazes me all the time. Price does not include shipping, let me know your zip and I can get a quote to you.
