My only disappointment with the modules is the poor thermal design. It would have been nice if they built them in a way the could easily be attached to a heatsink.
They only get slightly warm after playing for awhile, but I haven't pushed them very hard. I can imagine they would heat up a lot more if they were used as a small sub amp that was often pushed to clipping.

/U.
I didn't say I was worried, I just said it would have been nice if they were built in a way that allowed a heatsink to be attached.
The continuous output power these modules are capable of is a lot less than the devices could handle if properly cooled. The proof of that is in the datasheet

You can buy the 1000ASP module from 2 sources - Marchand Electronics,
http://www.marchandelec.com/amplifiers.html
or this guy
http://search.ebay.com/_W0QQsassZaudiotek168
Both sell them for about 500. each, so I would buy from Marchand versus a guy in Taiwan.
FYI, they are blowing out the NHT Power2 for $499. that has 3 B&O modules inside - one 500ASP and 2 500A.
see post 20 -

"The Power2 uses one 500ASP and TWO 500As. The amplifier channel on the 500ASP does nothing. This way both channels have absolutely identical behavior since they use exactly the same amplifier module."
If you buy two Power2s, you have 6 modules.

Hello
I build a 500A
http://www.icepower.bang-olufsen.com/files/solutions/icepower500adata.pdf
I doubt on connecting connector JST
the data sheet said something (page 3/16)
and serigraphy said something else
where is the pin 1?
Thanks !

We make powered loudspeakers and we have been using the 1000A, 500A, 200ASC and 500ASP quite successfully since 2001. We are very happy with the reliability and sound quality as are our customers.
We are fully aware of the limitations as well as the pluses of the ICE Power modules. Yes, with sine wave testing you cannot use the amplifiers at full power at 20KHz. But music does not have levels at 20KHz that high. With music there are no limitations.

I thought those might be it too, but if you look at the block diagram in the 200ASC datasheet it shows the "DC blocking" comes after the input buffer.
The ceramics by the inputs might just be for RF filtering. I will have to probe around a bit and see if one side of the cap is connected to ground.
