I owned one for awhile and thought it sounded pretty good given it's pricepoint. I wish I could be more specific but I sold mine off around two years ago so any comment would be from vague recollection. One thing to be wary of though is that the amp was designed to be run continuously (it has no on/off switch) and the constant plugging and unplugging of the power cord can be pretty tough on the tubes. This was a particularly big problem given the crappy nature of the current production 6DJ8/6922 tubes and the exorbitant price of quality NOS tubes.
