<font color='#000000'>No experience personally, but alot of people on X forums complain about high hiss and very little power. Even Sony based forums too.
Stay away from these the amps are garbage 0.6% THD in anything is unacceptable especially when the 4ES and 7ES were rated at 0.05% THD
If you want Sony get the 4ES or 7ES. Otherwise look to Marantz, Denon, or Yamaha, these are the only companies I'd buy from.
