The LM-845 Premium is the result of many years of 845 Triode single-ended design research. Thanks to its exceptional design and manufacturing quality, it is fast becoming the absolute reference in the high-end amplifiers world. With a power output of 2 x 30W, it can be used with most existing reference speakers.
The LM-845 Premium is a combination of two units. One is the amplification unit and the other houses the high quality output transformers. The LM-845 Premium uses Shuguang 300B tubes as drivers, the 310A and Shuguang 12AX7 in pre-amplification.
There are two user bias controls for the 300B and 845 valves. Bias adjustment is made easy with two meters on the front plate to allow you to monitor bias and make adjustments. A negative feedback switch is on the front plate so you can choose between two levels of NFB to enjoy the different styles of sound output.
The LM-845 Premium uses 8 transformers for power supply, filtering, coupling and output.
