for the NU3000


This is a low-end (in price anyway) "pro" amp. Alleged output is 2x1500 w/ch (peak) with reported 8/4 ohm RMS of about 600/300. Damned impressive for the price ( <$300 delivered). Note that "stock" this amp has a pc-type fan and produces pc-like fan noise. For home use, some DIY'ers install a quieter fan. I said, WTF, this amp as marketed is in a rack of other equipments, pumping out a huge signal; For (presumably) gentler home use, why not disconnect the fan entirely, remove the duct, leave the top off, passively cooling it? BE ADVISED YOU DO SO AT YOUR OWN RISK: (A) voids the warranty, (B) presents a shock hazard (unless you put a screened top on) and (C) the long-term reliability of my mod is unknown. That said, I have many hours playing this amp and so far so thermal shut-downs, nor any audible ill effects. It is possible, but untested, that the thermal shutdown will still work even after my dubious mod.


Product Weakness: Fan noise unacceptable. Fan can be replaced or disconnected at cost of voiding warranty, saftety and long term deterioration risks. Twist-lock speaker connects require DIY adapt.
Product Strengths: Inexpensive, powerful, extremely efficient class D, sound quality good to excellent. Perhaps make you feel stupid for paying more for something else. Blind test, anyone?
