There's a sticky at the top of this list announcing that Ice power amp modules will become available at PE in July. There are a bunch in photos, but no descriptions or pricing yet.

Mixed news IMO. Some of these Icepower modules are at least 10yrs old. On the one hand they are probably far more reliable than the direct from China stuff, but on the other hand you've got better newer Icepower amps and now the truly impressive TI TPA3250/1/55/45 series ('made in America' no less for those who value that). Be cool if PE had a partnership with TI instead...

Old or not, I was checking out a couple data sheets and they're darn impressive. The cost will be the kicker, particularly for the boards that have the power supply integrated and thus eliminate a whole other component to build or buy.Electronics engineer, woofer enthusiast, and musician.

The 1000AS and 1000ASP are good only for subwoofer duties, as the top end drops off.... and yes, they are much older design. Would have been good to get the newer designs, but only the 50ASX seems to make it... not the higher power ones. So a lot depend on what these are prices at. If they are priced aggressively like how the 250ASP was when it was on clearance then it might be worth it....

I don't think any of these will compare in sound quality to the Hypex Ncore stuff, which I use in my current designs,
but for low frequency duty, cheaper builds and if the cost is comparable and seeing how I could have them the following
day, with free or very low shipping cost and no "duties". They could be very cool!Guess xmax's age.
My guess: 15. His grammar is passable. His trolling is good.

Where do you find this code? Must you be registered for it?

Not sure if it's okay with PE to provide the link and code info so that's all I'll say. There is a lengthy thread or two at diyaudio. These have been well vetted the past few years and there are solid China-made versions on ebay as well. But the TI USA price is hard to beat. At .006% THD These amps are much better than the ubiquitous and very good TPA3118/6 and should be short-listed for any diy'er. I can't think of a better price/performance amp at this price.
