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.

Tony, ICEpower modules are by now legacy parts that some very experienced amp designers are still able to use, together with a great deal of creative ingenuity, to implement amplifiers that make actual music... By themselves, ICEpower modules inside bare bone amp implementations have audible limitations... They lack subtlety, and do sound "matter of fact" to say the least... That is, if one wants to be kind. Hence the stereotypical stigmata -- only occasionally unjustified -- of the "class D sound"

Hypex Ncore modules are a totally different kettle of fish... Even utilized into very simple amplifier implementations, without custom circuitry for power supply regulation, fanciful input signal management, etc... they make absolutely wonderful and effortless music, with lots more power than the 125ASX2s.

Hence my recommendation is... If you are comfortable with the joys of DIY... Source a couple of NC400 modules with their matching power supplies, some quality connectors and good wires/solder, perhaps a pair of reasonably looking enclosures.... And get yourself some magnificent sound.

Could you do even better than Ncore NC400? ... Of course.... NC1200 commercial amps are bound to sound even better.... Merrill Veritas, Acoustic Imagery ATSAH, Mola-Mola, but.... Their price ranges from $9K to $15K.

I can only echo what Wilsynet has said.... A statement in the general form "Ncore is very good for a class D amp" represents a total misrepresentation of Ncore performance.... Ncore tecnology delivers great music in the absolute, to any lover of good sound who is able to overcome obsolete "class consciousness".
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.
