Audeze MM-500 Headphone


While I was supremely enjoying the Audeze LCD-5 Headphones on my E.A.R. HP4 Tube Headphone Amplifier and the Manley Absolute Tube Headphone Amplifier, Audeze came up with the new Audeze MM-500 Headphones to review.

Zesto Audio Bia 200 Select Stereo Amplifier:  World Premier Review


The brilliant late audiophile, J. Gordon Holt, once wrote that if the purchaser of a fine system was torn between buying a great pair of speakers or a great amp, one should choose a great amp and a good pair of speakers that fit your basic needs. He commented that he had heard numerous systems... Read More »


Audeze LCD-5 Flagship Planar Headphones


Cutting right to the chase! I hypothesize that the excellent performance of the LCD-4 was criticized by many for its excess weight, and that the design required a makeover. At the same time, the CRBN Electrostat was bubbling up in R&D and would set a new musical standard for any headphones at half the weight. Most... Read More »

RSX Beyond Phono Cable with DIN Review: Part Two


I rarely revisit my complete reviews, but the RSX top-of-the-line Beyond phono cable with DIN connector has revealed state-of-the-art attributes that are stunning to this reviewer.

Aidas Audio Gala Gold LE MC Phono Cartridge


When it comes to turntables, I have to admit that my top MC reference remains the Aidas Mammoth Gold. It is the benchmark by which I compare all comparable MC cartridges.

The Zesto Audio Leto Ultra Preamplifier: Premiere!


I am an imaging junkie. Musical images, properly recorded, must have realistic tonality, unwavering stability, a rounded aspect, and—whether vocal or instrumental—must be room-present.

Grado Labs Lineage Series: The Flagship Grado Epoch3 Phono Cartridge


We live in exciting times for phono reproduction, a new golden age for LPs from manufacture to playback. The key lesson learned since the production of full-range stereo LP recordings in 1958, some taped in stereo as early as 1954 and released in 1958, is this:  the weakest part of the chain is playback in...
