Rick interested in your thoughts on the singxer think of getting one also did it come with a US plug from appos, heard that can be a thing with some products from Asia, though I have not heard that from appos. Does it get hot, like other class a units, heard you need a a few days to break in which is par for the course. Thank you most interested in Z switch and how it compares to other 6 watt HP amps.
