Simply put, if lived up to a 1/4 of the hype, it would be mainstream by now, not just in the DIY world.

All in good time....Ncore has just recently been released.....

Perhaps you haven't noticed that there are more class d amps in consumer products now than all other types combined.....

If I tried ncore it would have to be a nIght and day difference from the class d I had in 97 cause that shit was sad.

I have owned three amps with switching power supplies, and they all sounded 30-40% better running on a battery.

I would buy an Ncore in a heartbeat if it ran off of battery.

In doesn't follow that the same must hold true for the ncore....

And by the way, it can be run on a battery, it would just be a bit more complicated due to the multiple voltages required...

I bet you are correct and frankly am miffed why they can't be operated on a battery power supply.

A switching power supply is a swirching power supply no matter what company makes it. My ears are very keen to electronic glare, and all switching power supplies on amps I have ever heard has that same electronic glare.

Replace the switching power supply with a battery, and voila!

You seem to have a problem comprehending written English.....repeat, they can be operated on a battery....why don't you give it a try and let us know how it turns out?

If you choose not to use the Hypex SMPS, you'd just need to supply +/-64v for output stages and +/-16-25v for input stages. The data sheets tell you all you need to know.

I've dealt with SMPS in one way or another my whole life, in and out of audio, usually with disdain unless I have to move them somewhere. All I can say is keep an open mind on these when paired as a system before you start hauling batteries in.

Try listening before you generalize and spread your dogma and your opinion will be taken more seriously....

The dogma and carp I'm hearing is from you. Others are not personalizing or getting defensive. It's not like you own the company or work for Bruno, but you sure are acting as you do.

If they are so good, they will rise on their own merit and not from those who chose to be nebbish in their fervent posts.

Unlike yourself, I have made no generalizations about class d or called anyone a cheerleader....in fact, all I have done is said listen before you judge because without any direct experience, you have no basis for making any qualitative statements.

Products don't become popular in a vacuum. They become popular because people think they are good, tell other people, and the cycle repeats.

So people are excited about this product because it seems to offer heretofore unheard performance at or greatly above its price point. You would think that would appeal to anyone with an interest in this hobby.

The linked article in the first post was written way back in 2005. Have any us heard from this writer or his company since then?

Before the net, there has been several great products with unheard performance over the yaers. The dealers just never told you about them. The Musical Fidelity A1 at $375 retail is just one of them. If you heard one of these in your present system today, you would be shocked. They are selling used on Ebay in the $300 range. Not bad since these were made 25 years ago.

Now before you make any generalizations, you need to hear one for yourself.

$1900 by the time you get the Ncores assembled in cases is a great value? And what will be the resale value in a couple of years?

Once again, it is becoming a circular argument...doesn't anyone ever learn?

Thanks for the tip...I will run right out and buy one....

I couldn't care less as I don't purchase equipment based on resale value-I purchase based on performance, and since there have been many reports of the ncore besting amps at many times its price, I would indeed consider it to have the potential to offer great value.

Why don't they just put a good linear power supply in it ?

It is a diy product. Feel free to put any type of power supply you want in it....

I am not spreading anything. I am just saying what I hear from SWPS. If you do not hear the electronic glare of SWPS, then you have no worries.

Do you work for Hypex?

You don't have to work for Hypex to have an open mind....
