RMAA: GloveAudio A1 24-bit

August 30, 2017 ohm

RMAA data preceding articles which rely on them is logical. Except as regards preparing articles for Headfonia, which always catch me up. Apologies. Please read this article in conjunction with and foundation today's Wayback Wednesday on Glove Audio's A1.

RMAA: HiFiman Megamini 24-bit

July 31, 2017 ohm

RMAA: Fiio M3 24-bit
RMAA: iPhone 5 SE 24-bit
RMAA: iPhone 6 24-bit
RMAA: Fiio X3ii 24-bit

I love how Megamini sounds. I love its warm, bursting midrange. I love its texture and stereo detail. Its instrument positioning is excellent. At the best of times, it harks back to Fiio’s original X3- a player whose hellish UI left dents in my walls, but whose pleasing sound was then and still is a bookmark in what I consider perfect warmth. Unfortunately, Megamini hisses way more than the X3 ever did, and more in fact, than any player I’ve tested in about two years. In fact, its hiss is on par with an iPod video from 2005.

This thing sounds good. Real good. It really fits in a front pocket. I has a real hold switch. And a damn fine balanced output. That it costs just ~350$ in Japan and another Benjamin abroad is shocking.

RMAA: nextDrive Spectra 24-bit

May 3, 2017 ohm

129$. 32-bit 384kHz. DSD up to 11,2MHz. All thanks to a plug and play ESS 9018Q2C DAC, or what a smarter man than me hooted and hollered as high quality audio for the masses.

RMAA: Astell & Kern AK70 Kai (Ryuzoh mod) 24-bit

April 29, 2017 ohm

I consider myself something of a skeptic. Not a real skeptic. I let narratives carry me away far too often, and question things I’m down with far too seldom. But I try to make it a point to distain the belief in listening and believing. For audio stuff: that test has to be hardware, standardised, volume-matched, and snarky.

RMAA: iPhone SE 24-bit

January 13, 2017 ohm

So, the iPhone SE keeps test results within a decibel of both the iPhone 6 and the Apple Lightning to 3,5mm headphone adapter. It has a wonderfully low noise floor, shows reasonable stability under load, and at high volumes, presses into mid-tier audiophile DAP performance.

RMAA: Vorzüge DUO II 24-bit

January 12, 2017 ohm

Until this moment, until 2017 January 12 around 9PM, want to know what my most recommended portable battery-powered headphone amplifier was? I’ll tell you. It was Vorzüge’s PURE II (both versions). I can get it to eat up an overdriven Chord Mojo signal of 122dB and spit back around 120dB. At stable volumes, it measures between 118-119dB. It is an amazing amp whose load stability, signal to noise ratio, THD, IMD, and dynamic range are matched by almost no one.

RMAA: Cozoy TAKT 24-bit

January 6, 2017 ohm

Preamble: Cozoy have grown up. Neither TAKT nor REI spit mad Astrapi-like hiss from the headphone output. They are stable, solidly made, and, if you like well-machined metal, beautiful. Both also play to the low volume requirements of sensitive-eared listeners, yours truly included.

RMAA: nuforce uDAC5 24-bit

November 23, 2016 ohm

The uDAC5 goes for peanuts. It is well built, nicely branded, and compact. It converts USB signals to RCA stereo and coaxial SPDIF for outboard DACs and amps. It gets plenty loud, too: posting absolute volume levels roughly in the neighbourhood of an AK380. At those levels, however, IMD, THD, and stereo crosstalk numbers ramp up beyond reason. Its loudest stable volume is about a half decibel louder than an iPhone 6’s maximum, which is enough for me. If your iPhone is behind a EU volume cap, the uDAC5's power will surprise you.

RMAA: Linear Tube Audio MZ2-S 24-bit

November 18, 2016 ohm

The Linear Tube Audio MZ2-S, which I originally mistook for the microZOTL2,0, is a brilliant in/out valve amp whose design/performance niggles are minimal. According to Linear Tube Audio, its biggest design niggles: depressed power button, and attenuator noise, have been fixed. I can neither confirm nor deny this.
