....... seem to have a lot of NC500 makers, but limited NC1200 one I am not sure that he did post on your AV Forum thread if it was coll that posted thats me not Colin North.
On this site I am colmo on AV Forums I am Coll.
I was one of the first to purchase his monoblocks and thought I would share it with others. Sorry if I spoilt your thread.
Sorry for the confusion, Colin 🙂
I'm intruiged by the ATM version - they say they use a 1200W SMPS but the nice machined aluminium chassis doesn't hold the holes for one - but does hold a circular kind of shape suggesting a large toroidal...

As much as it warms my heart to see several folks profiting off of my ideas, perhaps you shouldn't outright lie about the measured specs of your amp.
"Output Power: 550W @ 0.1% THD load 2 Ohms / 700W 0.1% THD @ 4 Ohms load / 0.1% THD 400W @ 8 Ohms load"
Hypex's spec sheet says those are the watt specs at 1% not 0.1%
Distortion: 0.001% 4 Ohms 350W load 20-20KHz
"Signal / noise ratio: 135dB"
The S/N ratio is the rating without any buffer at all. Please provide us with comprehensive measurement specs with each of the following options you offer
1: LM 4562 based buffer
2: Sparko labs discrete opamp based buffer
3: Burson discrete opamp based buffer
If you want any hope of anyone taking you seriously, a good start would be:
1: Don't lie about specifications
2: Provide measurement results
Ooops.
I'm sorry for the inconveniences. The features have been mistyped (not a copy / paste). It is developing a new buffer. Measurements will be made with different operational amplifiers. Thanks for telling me the mistakes of the web. They are already corrected.

This chassis has two versions. The presented in the photo, it allows:
2 x NC400 + 1 or 2 SPMS600
2 x UCD180 + 1 or 2 SMPS400 / 180
2 x UCD180 + 1 power supply with toroidal transformer (obsolete)
2 x UCD400 + 1 or 2 SMPS400 / 400
The other version (not shown) allows:
2 x NC400 + 1 SMPS1200
2 x NC500 + 1 or 2 SMPS1200 (with original or new buffer)
If you can develop a low noise buffer board and provide the measurement results, this will be a very nice amp. I would consider offering an option with the Sonic Imagery 994 discrete opamp as well because it's better than both the Sparko and Burson. I have tested all 3 already with the NC 500.
Model 994Enh Discrete OpAmp
NC400? I thought the OEMs are discouraged from providing products based on that. Or are you just selling the chassis to the DIY folks?
Since fabricate by hand, I must have all options available. If someone asks me an amplifier with NC400, supply it. And if I ask only the chassis, too.
Hi Bavmike
I know you have both the Hypex buffer and the Nord buffer and you say that the Nord gives more noise with the Sparkos op amp. Having examined them both can you give an opinion as to why this is.
Probably because I shared photos of my NC500 input buffer using both Sparko and Burson discrete opamps in it talking about how good it sounds. I encouraged Boggit to build an input board made specifically with a dip 8 opamp socket so he can use a variety of discrete and IC opamps to tune to subjective tastes.
It's all on record between this thread and the Ncore thread.
Edit: I just noticed a pile of posts have been deleted where Boggit decided he would build the custom input buffer based on my suggestion. All I can find is this, but all of the previous conversation was removed for some strange reason. We skip right from Nov 17th until Nov 21st. I wasn't aware there was any violations of the TOS during that period.
