You really cannot trust what people who sell both modules say about the sound. They were selling the more expensive Ncore amps long before the less expensive 1200AS came out. If they said that the Ice was better they would lose all their stock of chassis and amps and input stages and power supplies used in the more expensive Ncore implementations. I am not saying which is best. Just saying. I have read of two A/Bs where the stock 1200AS2 was preferred over the Nord one up NC500. What I will be selling is tweaked mono 1200AS1s. The tweaking here is extreme. These sound nothing like a stock stereo module in a box. Of course, you cannot trust a word I say, as I am the seller. However, my amps will have a 30 day in house money back guarantee. Everyone can hear for themselves. You can trust your ears!
By the way, there is no one that I know of that has found the 1200AS modules not able to drive their speaker (and I mean super loud!). I don’t know anyone who has tested the modules for power at lower impedances. The 2.7 ohm minimum by IcePower on the spec sheet is probably just a conservative rating because they intend to sell these super high powered modules to PA users and sub amp manufacturers (you don’t want your amps going into protection in the middle of a concert!!!). 2.7 ohms is three 8 ohm speakers in parallel. I will be testing the modules at 2.7 ohms and at 2 ohms and will let everyone know how they do. I expect the protection circuits will come into play here. I am guesstimating around $1400 watts into 2.7 and around 1000 into 2.....then they shut off. I could be way off here....we shall see.
