I was talking about the Behringer amp that was linked, and the 200w amp that I referred to as drawing 1500w is an Aragon.
If it's one of the older Aragon amps, it is rated 20hz-20khz @200w continues into 8ohm, more than doubles that into 4ohm, and stable into 2ohm but, IIRC, it doesn't quite reach 600w before shutting down.
Update for anyone keeping track. I decided to take a risk and buy a used Crown XLS602 off Ebay for $200. Of course the seller claims it all works. Good seller ratings though, and free shipping offered on a ~30lb amplifier, sure I'll give it a go. Worth a little trust for 1200W into 8-ohm bridged! Plus that leaves some room in the budget for an ART cleanbox pro.
That's a nice amp. You will need the line driver too. The Cleanbox or the teal Radial book-box are good choices. InDIYana used a 402 the first 2 years in Richmond. Some have modded the fan to either a wall-warted DC type or removal in low strain uses.
FWIW, I have the XLS 1002 driving a Alpine swx-1042d and I'm happy. I've run it with the Bash 500 and Yung 300-6 and I'm happy in all cases, but the Crown can run it bridged at 2 ohm safely and I was quite surprised how well it compared to my much larger subs.
Interesting that in his conclusions he states "Can it be used for hi-fi use? Sure but it will severely limit both the resolution and potentially bandwidth of upstream sources. Its best use would be as a subwoofer amplifier."

Funny that the Yung SD300 plate amp is the monster deal of the week.
I saw that this morning and had a good laugh! As @Wolf suggested I'm going to look into a fan mod. Seems like there's noctua fans out there for about $15 each that are probably quieter than the stock fans... even if just based on word of mouth / pedigree alone. The thermal switch idea is interesting too... never wired one of those up, so I'd have to do a little research.

Ben... This has me thinking about my downstairs AVR setup too. I am currently running two 12" RSS HF 4ohm subs off the Crown XLS1002, but using a mini-dsp and RCA's into the Crown. I also have a hypex NCore 2x500 watt being fed by the Preamp outputs on my Marantz AVR. I kind of wonder whether both of those systems would be noticeably better with a Cleanbox Pro converting those to balanced before the amps too? Seems like a lot of effort to fix something that isn't really a problem right now (probably just an ignorance is bliss situation). Thoughts?
Don't fix what's not broke...
The only way to truly improve total performance would be to get a preamp that had balanced output. A clean box will only increase the amplifiers output, it can not reduce the signals distortion.

Hey Ken, I agree that the cleanbox won't reduce any distortion, but I would like to think it will allow me to send a less distorted signal from my AVR in the first place. For example, right now I have to put my AVR's subwoofer output at max (+12) just to make sure I'm giving my amps everything that I can squeeze out of the AVR. I would imagine this means I have higher chance for introducing distortion when I turn up the volume on the receiver and have that +12 setting for the sub pre-out. Of course I have no measurements to confirm any of this... just thinking out loud.
I have the SD500-6 with ultimax 12" in a sealed 2cf enclosure stuffed with fiberglass... 2cf before subtracting driver and amp volume so it is still probably a bit small. When running test sweeps it seemed to dip in output before the boost kicks in. Thinking a bigger enclosure may help remedy that.
But, I put it all together just before moving and haven't pulled it out of storage yet to do more testing.

Or added a thermo switch to kick it on when the heatsink gets warm enough.

Pretty good link to show measured versus advertised power of Crown pro amps here:

Get the Radial if you want cleaner, as it has Jensen transformers doing the conversion. About twice cost of the Art box.

Chances are the distortion figures from 5 to 12 db at the avr is negligible. I would spend money elsewhere.
I've bought several BASH amps, and have been pretty satisfied with sound and reliability. I bought 1 Yung amp for a sub, and it failed within 2 years.
