With all due respect but in the interest of full disclosure, for those considering NC1200 amp designs it appears that there is a bit of misinformation here regarding the boards and components used in the Mola Mola Kaluga amps. According to this
response directly from Bruno Putzeys about customizations he makes to the OEM boards for the Kalugas (additional details about the changes are in the linked response), I quote this excerpt for your reference:
1. Lowest distortion input stage. Not available as an OEM component from Hypex.
2. nCore 1200 module with much higher quality components, selected by Bruno for their sonic qualities. Not available as an OEM component from Hypex
3. Switching power supply developed especially for Mola-Mola. Not available as an OEM component from Hypex
1: Yes the input stage on the Mola Mola Kaluga is not available to OEM's. This is 100% correct. Bruno is not lying. The input stage that the Mola Mola Kaluga uses is very close to the input stage of the Hypex NC400. It's designed to be 100% transparent. This is also the reason why some folks think the Mola Mola Kaluga is dry and cold sounding. Simply because it is designed to add 100% nothing to the incoming signal other than what it's provided. 100% transparency. For many, this is undesirable. If this wasn't the case, this would be the only amp anyone should ever want if shopping in this price range or higher.
2: The "much higher quality" components available exclusively on the Mola mola NC 1200 unit, are also not available on the $50000 Bel Canto Black system, $12000 Merrill Veritas amps, $10000 Acoustic Imagery Atash 1200 amps either, you are right. So I suppose the end listener can decide if these "exclusive" parts are a deal breaker or not when choosing their Ncore based amp.
3: The SMPS1200A700 power supply used by Bel canto in their $50000 black system, Merrill in their $12000 Veritas amps, Acoustic Imagery in their $10000 Atash 1200 amps, and the Nord in their $1670 NC500 based amps, may be slightly different than the Mola Mola amps use. But by how much should be determined by the end listener.
And yes it is true that the big heavy LPS the Theta Prometheus uses in their $12000 amps is inferior to the Hypex SMPS. The only reason I can see they used it is to make the amp big and heavy to cater to the status quo belief that "bigger and heavier is better" Which is very true as seen by sales statistics.
