    Greg, you said that I said that they are lying.....so I responded to that part since I never said that.

    All vendors are not in a box. Some are totally trustworthy. I did not say that "all vendors cannot be trusted". Again, you are putting words in my mouth.

    Aj,
    The AS700 is an old design that was updated recently......but still very old technology. The IceEdge technology is the new IcePower technology. They have been working on it for 7 years. Please do some research. The 1200AS2 in the one and only module from Icepower that uses the IceEdge technology and was just released in Nov.

    I cannot yet add an attachment but if you search you will find a very long article on Audioxpress about the IceEdge technology.

    Okay Rick,

    You're right, you didn't say they are lying exactly.

    You said: I personally would not trust anyone who sells both to tell you what is really going on.

    Surprisingly enough, a similar thread was started in Audiogon which was taken down and then it popped up here with the same words. Folks who doesn't own amp from any of the manufacturers are recommending them without any experience what so ever. Even before buying this amp, I had asked Colin about them (he had the sample 1200as2 at that time) and he said he preferred the nc500 but I wanted to hear it myself and there is no doubt the 1200as2 beats the nc500 in my system.

    Both amps, the 1200AS2 and Nords NC500 (w/ SI 994) are transparent in nature and their sonic signature is also very similar - I have A/B them in two systems (mine and friend's system with Verity speakers) couple of times so far but in both the cases I prefer the 1200AS2.

    Yes, it came out in fall of 2014 but is still based on the very old technology developed 10 years ago or more (updated somewhat). Only this new IceEdge technology is the really new stuff (7 years in development). I am not saying the 700 is not good. PS Audio is using it in their class D amps with zero feedback buffers ahead of it.....getting some nice reviews. One of the first amps I want to A/B with my 1200AS2 will be the mono block PS Audio amps.

    Dev, I started the thread on Agon and yes because of a bunch of trolls it was taken down. I did not start this thread if that's what you are implying.

    I have listened to the 1200as2 for several weeks now in my very revealing system and I think it is very good as I have said. I have not heard the the NC500 which is why I pointed to the vendors who sell them and what they told me directly. I have heard the NC400 and it didn't sound anywhere near as good as the 1200as2 to me.

    I don't recall anyone recommending the 1200as2 who hasn't heard it but maybe I missed that post.

    are you sure of it ? weren't you the one who recommended the amps from Nords and other manufacturers without hearing any of them ? how do you know they all sound the same ?

    One thing I would point out is that comparisons of the 1200 AS2 to amps using NC-500 modules does not seem fair. Most of the NC-500 builds being used for comparison are dual mono amps with completely separate power supplies for each channel. In my experience full dual mono designs have an advantage in terms of sound staging and often dynamics as well.
    I am looking forward to seeing what happens when we get a true dual mono amp with two 1200 AS1 boards (or mono blocks, whatever) as this should be what is compared to the dual mono Nord amps (etc) based on two SMPS 1200 and two NC-500 modules.
    I think that they cannot easily be compared because the new IceEdge based line is an "all in one" design with the PSU on the same board and input buffer integrated with the comparator on a single chip. This means three things: first, that the reletive placement of components is already optimised to reduce interferences; second, that the tolerances for the input buffer are much tighter than what you would expect of discrete buffers, even more so with discrete opamps; and third, the IceEdge must be treated as a single object with 26/29 Db of gain whereas the NC500 is just the final stage of a power amp with a 16Db gain (IIRC).

    Hence they are two fundamentally different objects, but most importantly it is easy to cripple the performance of NC500 based amps by not properly matching or at least not properly sourcing high quality components for the input buffers and, even more importantly, by placing the boards in a suboptimal way inside the amp, causing electromagnetic interferences. The latter in particular may make a big difference since class D amps are known to be extremely sensitive to that. With the IceEdge stuff, you just put it in a case, finito.

    Which one is better of course I do not know. Because of the scarce availability of 1200AS2 modules in Europe until recently, months ago I opted for the Apollon NC500 based moniblocks with SI opamps (these have correct placement of PSU wrt the other boards). I would be very curious to listen to 1200AS1 based monoblocks, until then I cannot judge – but I would not he surprised if some NC500 based ones rated better and other worse, just as a consequence of internal design, even if they use (different) input boards with the same opamps. In my limited DIY experience I have observed noticeable sound changes just by slightly reorientating transformers, twisting power supply cables, rerouting the latter differently, etc...
