Thanks to all who've put some comments onto this thread. There really is no one sided coin to simply anything hence nothing is absolute perfect. I originally posted this thread because my initial assessment of my amplifier purchase from them was far from perfect. However, the amp has had no problems so far and sounds quite nice. I've never bought Sophia specific tubes so can't comment on tube related stuff. But since I have been a customer of them at one point in time, they have re-assured me of my purchase and responded back in an orderly time.
