Sound Reproduction: Psychoacoustics of Loudspeakers and Rooms

By | December 11th, 2017|Categories: Audioholics|Tags: |

People unversed in technical terminology will talk about an audio system’s ‘sound quality,’ and what they mean is how good does the system sound to them and how ‘accurate’ is it. But what constitutes ‘sound quality’ exactly, in a more precise and scientific sense? Many people have spent a great deal of time and money chasing the better end of ‘sound quality,’ but without an understanding of what ‘sound quality’ is, they are stuck in a blind search for something that simply sounds good to them that they happen to chance upon.

Understanding the Speaker Impedance Specification

By | December 7th, 2017|Categories: Audioholics|Tags: |

Audio specifications fall into two broad categories: Those that are nice to know, from an enthusiast or intellectual standpoint and those that are genuinely helpful in assisting you to use, install or set up your equipment. Some specifications have a foot in each camp, so to speak, and serve both a practical and theoretical purpose.

Amplifier Power Output

Usually expressed in watts, this specification is probably the most often sought-out and compared number for amplifiers. Assuming the manufacturer has rated their equipment accurately and honestly, the wattage spec is useful in determining whether that particular piece of equipment is a good match for your speakers in terms of having sufficient power to drive it to SPL levels you find satisfactory in your listening room and also to decide whether your speakers and this amplifier are a proper match from a power output/power-handling perspective.

By | December 5th, 2017|Categories: Audioholics|Tags: |

UDP-203 & UDP-205 Introduction

Oppo UDP-205 HeroIt’s getting pretty boring reviewing Oppo Blu-ray players. Make no mistake, I mean this as a compliment, of course. This is the 4th-generation universal Blu-ray and 1st-generation Ultra HD Blu-ray player platform for Oppo coming in two flavors: the UDP-203 and souped-up UDP-205.

Both players are virtually identical in audio and video capabilities in that they play 4K Ultra HD Blu-ray with HDCP 2.2 and BT2020 compatibility, regular and 3D Blu-ray, DVD-Video, DVD-Audio, SACD, Audio CD; High Dynamic Range (HDR10), support for Dolby Vision (recent firmware update); dual HDMI outputs – HDMI 2.0 for UHD and HDMI 1.4 for audio; and an HDMI 2.0 input port for external streaming devices or set-top boxes and last, but not least, networking capability to stream from your NAS or external HDD loaded up with music and video files.Read the full article

Title II is Not the Net Neutrality You’re Looking For

By | December 2nd, 2017|Categories: Audioholics|Tags: |

The end is nigh for net neutrality as it exists today. Trump-appointed FCC chief Ajit Pai put forth a plan last week that promises to roll back Obama’s 2015 net neutrality policies. All that’s left is for the five FCC commissioners (three of whom are Republican) to vote in December. They will of course vote along party lines making the end of Obama’s version of net neutrality a virtual certainty.

The Obama net neutrality policy is usually seen in one of two ways, depending on which side of the political divide you stand:

Star Wars Battlefront II: EA Embraces the Dark Side of Gaming

By | November 20th, 2017|Categories: Audioholics|Tags: |

The economics of videogames is serious business. Budgets for high-profile games routinely outclass those of blockbuster movies, not to mention the GDP of small independent nations. But, with great budgets come great expectations for profit, which is why publishers are always looking for ways to wring even more from the games they release.

One of the latest methods for squeezing more profit from games involves complex in-game economies designed to gently nudge players into spending real-world money on “microtransactions”. The ill-will generated by the growing prominence of microtransactions in videogames reached crisis proportions last Friday with the release of Star Wars Battlefront II by EA.

By | November 15th, 2017|Categories: Audioholics|Tags: |

Subwoofer manRythmik Audio FV18-1c.jpgufacturer Rythmik Audio has recently released three powerful new subwoofers that takes their vaunted Direct Servo technology to new extremes of power. Their former flagship subwoofer, the FV15HP which we found to be a very high performer in our FV15HP review, was a formidable unit that used a beefy long-throw 15” driver powered by a 600 watt amplifier in a large, ported cabinet. Rythmik’s three latest subwoofers, the F18, the FV18, and the FV25HP, go well beyond that.
