"Despite the Line Magnetic LM-845IA's scary-high voltages and intense heat, in the months it spent in my home it performed faultlessly, without stutters, burps, or parts failures. It brought a new dimension to my musical enjoyment, revealing the physicality and force in every recording I played through it, from Monteverdi to Merle Haggard, an experience that provided addictive amounts of fun. $4895 is hardly a modest sum, but using nearly any sensible metric of value, the Line Magnetic is a stone bargain. If Rubens had lived in the hi-fi age, I imagine that he would have appreciated its way of making music pulse with vigor and vitality. Unless you listen to little except baroque trios, and maybe even then, you should find a way to hear one. It's that good." Stereophile  |  Jun 18, 2021

The LM-845IA is a quality upgrade of the old LM-518 amplifier. It delivers twenty-two watts per channel. Single ended design, Pure Class A, Integrated Stereo Amplifier with 845 output power tubes. The rear-illuminated front panel meter is used to adjust the polarization of the tubes.

The use of high quality components (Realcap capacitors, ALPS potentiometer) wired in the air for the most part is the guarantee of exemplary reliability. Its transformers output are of EI type, specially disigned for power supply.

Its power and current capacity allows it to manage a very wide range of speakers. The use of the legendary triode 845 offers a listening to an unusual musicality.
