NCore vs. Ice -- single or separate cases

Hey guys,

I've recently gotten a bug that I can't shake. I went to sleep thinking about it last night.

I want to try out a class D amp.

I've narrowed my choices down to something based on either the NCore NC400 or the IcePower 125asx2.

If I went the way of the NC400, I'll be building them myself. If I went the way of the Ice, I may build it myself or just buy the assembled units. Either way, the NC400 builds will run about twice that of the Ice builds.

Is there anyone out there that can comment on which is better? If the answer is that the NC400 is better, is it worth twice the price?

My next question is whether I should build the mono units into separate boxes or a single box? In other words, is it better to use a longer interconnect with a short speaker cable or vice versa?

Thanks.

Oh, last question. Why is it necessary to use two power supplies? My research indicates that one provides more than enough power for two NC400s.

I'm asking because if two power supplies are necessary, I'm going to go ahead and put them into separate cases. The cases are under $100 and a drop in the bucket at this point.

If you check the link I gave in my first response you may find a used amp for sale. Over the past few months I have seen 3 or 4 come up for sale at what looked to be a little less than the cost of parts. Gotta be quick though, as they go fast.

Tony, my own direct experience is with Ncore NC1200-based amps.... They are musical instruments... rather than "not bad for a class D".

By the way, my very first high-end amp was an Aragon 4004 during 1984 or so... Unless one thrives with nostalgia, most circuits today, including Ncore of course, would leave the brave old thing buried in the dust. G.

Tony, if you decide to use one single power supply, you better check with Hypex before you do.... Last thing you want to do is to damage both modules in one fell swoop.... Mr. Putzeys designed the power supplies to serve one module each. G.

You want both power supplies. One of the key aspects of a good amplifier is a robust power supply, and having independent power supplies is a good thing indeed.

How does it compare to NAD? Compared to a 325BEE (or whatever designation they're using today), it isn't even close. The NAD masters series would compare more favorably if their M51 DAC is anything to go by.

Would be good to know what you're using as a preamp.
