My first foray into ICEpower and specifically the 1000ASP module was based on glowing reviews of the sound quality far more than power. I actually bought some DIY units out of Denmark and really liked the sound and efficiency. I bought the PS Audio for around the same price as a good seven channel 150w unit. But when you consider Bel Canto sells the same modules at $2500 for one channel and I got three, plus four more channels equal to their M300 for close to the same price as one mono, IMO that's a good value. The fact it has that kind of power is just a bonus. The seven channel PS Audio probably weighs the same as the 4311 and the Bel Canto Ref1000 weighs a whopping 13 pounds by the way...
To get down to 60wpc with the 4311, not only would you need to have all channels driven but also with a constant load. That would simply never happen in real world applications.
It wasn't that long ago that 60wpc was considered a high powered amp...so what has changed? Did rooms all of a sudden get bigger? Speakers become more inefficient? Or did power become a selling point that ignorant masses bought into?
I think there's a lot of the latter in play because the magic number became 100wpc and manufacturers were doing everything in their power to hit that spec with either design or with "manufactured" specifications. I don't think it was because of genuine need.






























I've heard bad implementations of very good components.
I'm also reserving judgment until I've auditioned or have heard 1st hand accounts about the Denon's performance regardless of the components. I'm going to trust that Denon and other manufacturers know what they are doing when it comes to the parts and implementation of their products.
