Thanks to its exceptional design and manufacturing quality, it is fast fast becoming the absolute reference in the

high end amplifiers world. 

With a power output of 2x30W, it can be use with most of the existing reference speakers. 

The LM-845 Premium is a combination of two units: One is the amplifier unit and the other is output unit.
The LM-845 Premium uses Shuguang 300B tubes in drivers, the 310A for amplifier and Shuguang 12AX7 in pre-amplification. 

There are two user bias controls for 300B and 845 have been used for bias adjustment and two meters has been

added to the front plate to allow you to monitor bias with ease. Negative feedback switch is on the front plate

that you can choose betweeen two levels of NFB to enjoy the different sound outputs.  

The LM-845 Premium uses 8 transformers (power supply, filtering, coupling and output)!
