I am going to keep this kind of short but I can elaborate a little more on the power supply as I have more info from a very reliable source..
So for starters
NCore 400 designed for much lower power output and one of its issues is that when fed with US 117 Volt power the power Sags great with the Switching supplies and to gain power the distortion goes up greatly.. Ncore 400 fed in Europe on 220 Volt supplies believe it or not will sound much better.. The Switching supplies being used by most companies are of course variable voltage and when they are fed with 220/240 they work decent and on 117 not so much.. This doesn't matter much for this thread as we are talking Ncore 1200 but a fun fact to know.. The feeling I got out of this part of the conversation was if you keep the output power low like 50-100 watts , the Ncore 400 can be very nice for low cost amps.
Ncore 1200 is an entirely different beast.. Designed for much higher output it requires alot more work to get it right.. Its funny you guys make it sound like you just buy a module and hook up power and voila you have an amp.. Not quite with Ncore1200.
The power supply to drive Ncore has to be more than a power supply.. It must have starting circuits and a Microprocessor to control the Amp Module.. This is a requirement and that you must have to control the Amp, regulate it , keep track of all kinds of things to keep the amp running and doing what it needs to do.. As power ramps the micro tells the module what to do. The sync between the Micro and the Amp module are key to its sonic signature and because Hypex custom builds the Theta Ncore1200 modules for Theta, the magic is the way Theta has dialed in the Control and Power feed to the Module itself..
I can tell you they tried switching supplies and never got to the sound level they achieved with the Reich Linear Supply. There is something that I don't quite understand but what I got from this conversation was that if a Switching Supply was really high end and included Power Factor Correction it could be a nice alternative to the linear solution but the cost of the Amp might be 50K.. Apparently there are serious regulations with switchers and how they dump noise back on the grid and this is a huge certification issue here in the USA apparently.
The bottom line is this isn't a case of buying a Power supply and plugging it into a hypex 1200 and you have a working amp. Its a whole lot more complicated than that and I am not going to try and teach amp design to you guys because I am not qualified to do so
.. My friends in the industry don't want to teach you guys either because then they have more competition
So I see it like this - For lower powered requirements 50-100 Watts the Ncore 400 can do the trick for some people.. The 400 modules are popping up everywhere and from dozens of companies for prices that are amazing for what you get.. Nad's 7 Channel unit is 3995 on crutchfield.. Thats less that 600 per channel.. They rate it for 180 WPC and I can tell you that at 180wpc regardless of what they say the distortion will be very high..
For the high end Clients and by the way we are in the 20K and up forum last time I checked.. The Ncore1200 is what these people want.. It can be Mola Mola, Bel Canto has a 50K solution i hear, Jeff Rowland I am pretty sure is using it in their 925 monos but doesn't say so.. Read the specs , it looks like Rowlands using a high end switcher as it says its got PFC. I think those are 35-40K a pair.. There are quite a few guys doing the Hypex 1200 and I bet there will be plenty more to come.. Just so happens the Theta Solution is the least expensive out of the ones I've mentioned. More important is I don't know anyone doing a Multi Channel Hypex 1200 except for Theta with their new soon to be out Dreadnaught D !
Hypex Ncore as a AMP technology is amazing and I think over time everyone will agree with this. For High End people deciding to do Rowand or MolaMola or Theta , its all great and I am sure people will realize this when they get to hear them.. For others the Ncore 400 solution for a much lower cost solution is great as well.
Guys, I hope this sheds some light on what the Hypex Solutions are all about and for more detailed Hypex info, we probably should move that to a more detailed Hypex Thread if someone wants to start one..
This is the Theta Thread in the 20K and Up group and I am sending it back to that
