Introduction to the D-Sonic M3-5400-7

D-Sonic is a company that I had been tangentially aware of for many years due to their direct marketing efforts on websites like Audiogon. The brainchild of Dennis Deacon, D-Sonic was founded in 2006 to make high quality Class D based amplifiers marketed directly to consumers. I had the pleasure of having D‐Sonic's new top of the line 7-channel multi-channel amp in house for a few weeks and am excited to pass on my thoughts.

The M3 series represents D-Sonic's third generation amp. D-Sonic amps were originally designed around B&O ICEpower modules, but with the M3 series, Dennis has opted to move away from B&O parts. The specific unit I was sent, the M3‐5400-7 is a beast. Weighing in at 58 lbs, the amps front sound stage boasts a whopping 1500 watts into the front L/R channels (that's 1500 watts each!) and 800 watts into the center channel. The remaining four channels boast 400 watts each. This is massive amount of power and I was curious to see how it would perform in my theater, especially with some demanding and highly dynamic movie soundtracks.
