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.

Editorial: The Industry Learns a Lesson: The Death of 3D vs. Industry Predictions. Will this Change their Plans for Introducing 4K to the Public?

John E. Johnson, Jr.

The recent announcement that ESPN is eliminating its 3D channel on cable and satellite tells a sad story of overestimating the impact of 3D on selling more HDTVs. Although 3D movies continue to be released - for the time being - it appears that consumers are not interested in watching 3D at home. The "glasses" are claimed to be the scapegoat, but I think there is more to it than that.

How is bass divided among speakers?

John Johnson

How is the bass divided among speakers if there is no sub in the home theater system? If a 5.1 system has identical speakers all around with 15 inch woofers and all of the speakers are set to "large" on the processor, does the serious bass get evenly distributed to all speakers? Say, like an explosion or a dinosaur stomping? Is there much serious bass info sent to the surround speakers if they are set to "large"?

Bryston Mini-T Monitor Speakers

Jared Rachwalski

Bryston has a long history of manufacturing high quality amplifiers and digital components. Their products come with an industry leading warranty, reference-level sound quality, and above average build quality. For years their electronics have been paired with high end speakers at various shows, Thiel, Magnepan, PMC and other serious loudspeaker manufactures have chosen Bryston electronics to showcase their sound so I was very interested to hear that they were producing their own speakers.

Parasound Halo CD 1 Player

Rick Schmidt

The Halo CD 1 is a flagship CD Player from the well regarded, San Francisco based, Parasound. CD Player? Surely I mean 'DAC with Transport'. Nope. CD player, put your CD in, music comes out. No, you mean it's part of a server system, the data is stored for later retrieval by a computer system. Well, only if you count the internal buffering and Intel ITX computer running Linux inside the CD 1. In implementation then the CD 1 is quite modern, it's a computer, dedicated to CD playback only. In practice, it's an old fashioned (and in this case, that's good) CD player.

Pass Labs INT-150 Integrated Stereo Amplifier

John E. Johnson, Jr.

Pass Labs is renown for their high end preamplifiers and power amplifiers, but they also have integrated amplifiers as well, which include the INT-30A and the INT-150. Here, we review the INT-150, which, as you can imagine from the model number, outputs 150 watts x 2 (into 8 ohms). It has the same massive build quality as the other Pass components I have reviewed, and also, its own distinctive sound, as I have found with the others.
