Grado Labs GH4 Limited Edition Headphones: A Must Own!

Grado Labs GH4 Limited Edition Headphones

The Grado Labs GH4 in place at Chez Levi (photograph by Bob Levi)

The GH4 is Grado’s second foray into creating headphones using Norwegian pine, upping the ante and overall headphone performance quite nicely along the way. By my count, Grado has used two types of mahogany, maple, oak wood treated by a whiskey barrel company, cocobolo, and painted maple in their lineup. Plus, at my request, Grado discovered a unique striped oak from California utilized in the Los Angeles and Orange County Limited Edition 25th Anniversary Headphones.… Read the full article

The Zenith of Headphone Planar Technology and Headamp Design from Audeze: World Premiere Reviews of LCD24 Headphones and King 2 Amplifier

By | August 2nd, 2019|Categories: Positive Feedback|Tags: , |

audeze lcd24 headphones

As an audiophile and headphone aficionado for over half a century, I was only aware of two ways headphones could be operated until 2008:dynamic headphones and electrostatic headphones. Grado, Beyer, Sennheiser, and Sony owned most of the market share of dynamic cans, while Stax and Koss produced electrostatic models. Headamps dedicated to either format was up to the provider of the cans, or merely a convenient quarter-inch phone jack in your preamp, tuner, or tape player. You would be shocked by the poor quality of the cans in use in recording studios in the last century.… Read the full article

PrimaLuna EVO 100 Tube DAC – Premier Review

By | April 18th, 2019|Categories: Positive Feedback|Tags: , |

PrimaLuna EVO 100 Tube DAC

Digital Audio Converters (DAC), which take the carefully crafted digital signal and convert it to analog, mostly matured between five and ten years ago. Companies like DCS, Playback Designs, Theta, and more, pushed the chip manufacturers to develop extraordinarily complex and powerful designs, and finally have nearly eliminated jitter and other innate problems. Musicality improved with every generation, as did computing power, topping out about a decade ago with chips used quite often today for stereo PCM 24/192 and up to 2X DSD.… Read the full article
