Magma M

Single Ended Mono Block Power Amplifier

After "Big" Magma NAT introduced "Small" Magma M high power single ended direct heated triode amplifier. At almost near half the price of "Big" Magma there is over 90% of sound quality from Magma M. Magma M may drive equally both dynamic or electrostatic modern type of speakers.
