I'm offering a bounty any dreadnought 1000. My bose 1801 fully recapped and with special r3 fix with a recapped matching 4401 4ch preamp. Here is a pic of the amp.
You phase linear guys might not like hearing this but from first hand knowledge my sunfire signature series Bob carver 400w@8 800w@4 x 5channels all driven will smoke any pl700....btw I have owned and built several nice pl700 for customers.
