Both packs of active devices are of high grade and have high reliability.
Hand crafted wide-bandwidth output transformer (custom designed for NAT ) is used in this unit.
Open bandwidth is from 4Hz – 400.000Hz. That is extremely excellent for high direct current single ended transformer coupled operation mode. Even the square wave response is perfect that indicate extremely quality amplification. Total weight of output transformer for one channel is approx. over 15lbs (7kg).Output has separate tap for single ended and balanced operation!
By specific technical approach mention output transformer in combination with special selected j-fets with vacuum tube support may drive easy any type of interconnect even very long length cable.
Zero feedback concept is well known also as the best solution for purity of sound reproduction without negative influence from feedback circuit. Also there is no any capacitor on direct or indirect signal path.
Attenuation is based on high reliability relay (pure silver with gold plated contacts) network that is computer controlled – there is 96 position of attenuation and always is only one (single) laboratory grade resistor on signal path.
Magnetic is equipped with remote control unit made from solid block of aluminum.
Power supply section also speak for itself. High capacity (approx. 500.000 uF of capacitance) supply is used as the best solution for low voltage power supply section. There is energy more then 550 joules, higher then in most power amplifier!
It is true dual mono construction - totally separate one channel from another.
There is separate voltage regulators also for all additional (for non signal path) stages.
On such a way sound quality is totally independent from line voltage instability and influence of wide variety noise that could be coupled across.
Also second power transformer supply digital circuit that control non analog preamplifiers function.
There is a built-in measurement for total hours of preamplifier accumulated work (tube duration) that is presented by led diodes universal meter (led indicator on front panel).
Quality of electronic material that is used inside Magnetic is on high level - special selected fet by industrial standard , 0.1% Vishay resistors, high quality transformer core, electrolytic capacitors of very high capacitance, gold plated teflon isolated connectors, pure silver input wiring…
Line stage works properly at all world wide AC line voltage from 100 – 250 VAC, 50-60Hz (set in factory).
