Gryphon's long-awaited pure class-A Antileon Revelation amplifier, the successor to the Antileon EVO, will hit dealer shelves late August in both stereo ($39,800) and mono ($45,500/each) versions. We used to say, “It will arrive late August if the creek don’t rise;” these days, we replace creek with tariffs.

The stereo model delivers 160Wpc into 8 ohms and 320Wpc into 4 ohms; the mono version increases that to 180W into 8 and 360W into 4 ohms. Output impedance is rated at 0.04 ohms for stereo and 0.02 ohms for mono. Power supply capacitance is 2×335,000µF for the stereo amp and…

The MXA-800 in stereo
I am always seeking out new and interesting music, by any means necessary. I stumbled on a fascinating new recording just as I was preparing to sit back to try to get a handle on how my system sounded with the MXA-8400. Live in Berlin, performed by Kinan Azmeh and CityBand (16/44.1 download, Dreyer Gaido 21163), is a live and lively recording of some fascinating music. In the years following the Syrian uprising in 2011, Azmeh created this music "inspired by anger, sadness, frustration, and above all the need to hold on to one's optimism, hope and creative tools…

I used my Audio Precision SYS2722 system to measure the Lyngdorf Audio MXA-8400. Although the MXA-8400 is an eight-channel amplifier, I performed a complete set of tests with one channel driven in 2-Channel mode (footnote 1), repeated some of the tests with two channels driven in this mode, then performed more tests with two channels operated in Bridge mono mode.

Because class-D amplifiers emit relatively high levels of ultrasonic noise, I inserted an Audio Precision AUX-0025 passive low-pass filter between the test load and the analyzer. This filter…

Instead of bluster, I sat through blessedly short, level-headed…

Not content to rest on its laurels, Accustic Arts has since replaced AMP V with (what else) AMP VI. The new product has a redesigned power supply that includes a new transformer and larger capacitors. US distributor Philip…

Digital's rapidly evolving technology made the next wave of DACs sound strikingly clear and quiet, with some touchy-feely hints of wetness to suggest a more natural transparency. Unfortunately, most of these…

That was through the super-transparent Voxativs. Now seemed like a good time to try the Fezz through my forever reference Falcon Gold Badges. Every time I go back to these speakers, it feels more like a marriage, with decades of memories to use as comparison fodder.

I turned twenty-one in prison doing life without parole
You can blame it on the sound quality of the Fezz Equinox or the persuasiveness of Alex Halberstadt—take your pick—but during this review period I climbed off my high horse and accepted Merle Haggard as my three-in-the-morning savior. Alex helped me recognize…
