These are in near perfect condition and were purchased by me from MBL USA as shop demo for $9600 +$80 for the remote control. Link to review: http://www.positive-feedback.com/Issue30/mbl8011.htm . I have the original factory performance sheets for this pair.
These amplifiers have been running on a power regeneration system since I purchased them. There has never been a poor sine wave or over/under power.
You can call to discuss on 951 768-1500.
Amazing amplifiers but I am an Aussie with no insurance here and need the money, however, will not sell below this price. I have a high-end Unison stereo amp I will have to be satisfied with.
Kind regards, John
