It is known that electric circuit contains Earth terminal, Live terminal and Neutral terminal. MS-NBX23 Pro. uses feedback loop concept that make use of the close relationship of E, N, L to "suck" out all those annoying noises inside the electrical circuit so that the filtering socket can supply tremendous clean power to Hi Fi systems. MS-NBX23 Pro. is so designed (with the MS HD 78K cryogenic treatment) that it can be used in any AC electric circuit from 100VAC to 240VAC, 50-60 Hz with no current limitation. Two methods suggested for connections (1) For those who have twin wall sockets system, first connect the MS-NBX23 Pro. to one of the twin wall sockets while the MS Filtering Socket is plugged into the other socket. Immediately enjoy the roaring supply of pouring clean power, just like sitting inside a theatre and listen to the real sound of orchestra. (2) For those who have single wall socket system, first connect the MS Filtering Socket to the single wall socket while the MS-NBX23 Pro. is plugged onto one of the MS Filtering Sockets. The result will be similar to the above, only the former has better result. MS-NBX23 Pro. and will also work with those are non-MS Filtering Sockets, however, the result will not be as the same as that with MS Filtering Sockets. The design concept for this product was to strengthen the filtering performance of the MS Filtering Sockets.

People would think of -196 degree Celsius when talking about cryogenic treatment. Celsius is normally used by observatory when describing weather temperature. Scientists use Kelvin (K) to represent temperature unit. Zero Kelvin means absolute zero of temperature, or -273 degree Celsius. Hence, -196 degree Celsius should be read as 77K, much simple and professional.

Why does MS HD POWER name their cryogenic technology as 78K rather than 77K? It is because their treatment technology is not using 77K temperature, they use a very special technology namely “78K Impassion Treatment Technology” to emphasise uniqueness.

Normal cryogenic treatment uses liquid nitrogen as treatment media. Cryogenic treatment can be divided into two types of method: wet type and dry type. Wet type makes the metal parts inside liquid phase nitrogen while wet type makes the metal parts inside vapour phase nitrogen. Liquid phase nitrogen treats metal parts rapidly but temperature control cannot be easily achieved. Vapour phase nitrogen treats metal parts slowly but temperature control can easily be controlled. Rapid decrease of temperature makes metal parts to have residual stress which affects the electric conductivity of metal parts. Slow and consistent decrease of temperature avoids residual stress in metal parts, hence increases electric conductivity of metal parts.

Deep cryogenic treatment does affect the arrangement of crystal structure inside metal parts in a rather small scale. That’s why MS HD POWER did not cryogenically treat their metal parts in the past time. In 2014, MS HD POWER put up a research on metal part treatment in associate with a deep cryogenic treatment expert in UK. They successfully achieved a unique method to increase electric conductivity of metal parts, “78K Impassion Treatment Technology”.
