So I've done my research. I know that the NU1000 is rated peak, and that RMS watts are more like 600-700 at 4 ohms bridged and 400-500 at 8 ohms bridged. But at only $150 brand new with free shipping, 6-7 pounds, and including a 3 year warranty, I can't see how this isn't a crazy good deal. 600-700 watts may not be huge in the PA world, but loud for most bass rigs. So I pulled the trigger. I have a Mesa 4x10 cab that could use 400-500 watts and an Acme Low B 2x10 that could use 600-700 watts. Perfect. I could even run them both at the same time. But then I discovered that DSP is an option on these units and that piqued my interest. After doing more research It seems like most recommend the DSP version. Its around 75 dollars more and that puts it out of interest for me. I'd rather save the cash. But then I saw a used one for only 100 bucks and I snapped it up. About 125 with shipping. Still cheaper than the non DSP version, but no warranty. I also discovered that these fans are ridiculously loud. Knowing I would probably end up replacing the fan, I ordered one from Amazon. It probably voids the warranty to do so, but I'm assuming the used DSP one wont have a warranty anyway. So my questions: Obviously the DSP equipped amp is preferable because it has more features and will be much more quiet with the upgraded fan, but is it worth the warranty trade off? What, in your experience as a bass player, are the biggest benefits of a DSP equipped amplifier? I'm not interested in house sound or PA stuff. What would be most useful for me putting it in my bass rig? Thanks for your help, and any experiences and opinions regarding Behringer's inuke amps are welcome, too.
