D-Sonic M3-5400-7 Class D Seven-Channel Power Amplifier

Mark Vignola

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.

Sony BDP-S5100 Blu-ray Player

Chris Heinonen

Last year, Sony's Blu-ray players did a great job of hitting these goals. Their initial firmware had an issue decoding Blu-ray discs to RGB that we discovered, but that was quickly remedied and after that the players performed very well. Sony elected to keep the BDP-S790 at the top of their lineup this year, and it remains one of my favorite Blu-ray players, but the other models have been replaced. One new model is the BDP-S5100, which replaces the BDP-S590 model that I looked at in 2012. Has Sony kept with their winning model from last year, or have updates brought us changes?
