The reference-system equipment used with both amplifiers included the Rowland Consonance preamp and the Apogee Stage loudspeakers. Program sources were the Oracle Delphi Mk.IV turntable and Oracle 345 tonearm with the Dynavector XX-1L cartridge and the Sony CDP-X77ES CD player. Other equipment used included the Mirage M-3 loudspeakers and (briefly) the Coda Technologies FET Preamplifier 01. The Threshold SA/12es and Muse 100 amplifiers were pressed into service where needed.

Loudspeaker cables were Symo (for the Stages) and AudioQuest Clear (for the M-3s).…

As can be seen from fig.1, the Rowland exhibits a virtually ruler-flat frequency-response curve. The 10kHz squarewave (fig.2) indicates a fast rise-time, with no significant rounding of the leading edges. Polarity of the Rowland was non-inverting, and input impedance at 1kHz was 20.8k ohms, 95k ohms, and 750 ohms at the 20k ohm, 100k ohm, and 600 ohm input settings respectively. It required 142.4mV to give an output of 1W into 8 ohms, a gain of 26dB. Unweighted noise was 75.3dB below 1W into 8 ohms. Channel separation was better than 105dB below 1.5kHz (actually…

Description: Solid-state stereo power amplifier. Power output: 60Wpc into 8 ohms (17.8dBW), 120Wpc into 4 ohms (17.8dBW), 215Wpc into 2 ohms (17.3dBW). Bridged power output: 240Wpc into 8 ohms (23.8dBW), 360Wpc into 4 ohms (22.6dBW), 500Wpc into 2 ohms (21.0dBW). Power bandwidth: 0.3Hz to 300kHz, –3dB. Slew rate: 70V/ns.

Input impedance: 100k ohms, 20k ohms, or 600 ohms (…

It's half past seven on a drizzly Friday night in New York City. I'm a little bit of a mess; soggy from the sporadic downpour, weakened by a full day's work, and still regretting the sub-par pork and chive dumplings I wolfed down earlier. All day long I've been fighting off the urge to inject myself with cold beers (preferably Guinness) and binge watch Wong Kar Wai films. It's one of those days.

I'm with my friend Brian Li and we're walking in the East Village. Our destination: Other Music.

Pause. Allow me to back track and offer you, reader, some…

SCENE ONE

The stage is completely darkened, save for a small pool of light L. and another R. At L. we see randy in his office, sitting with his feet up on his desk. Other than a computer and a telephone, his desk is…

It may have started back in 2011, when the crowd at the Grammy Awards let out a collective "Who?" as Esperanza Spalding was named Best New Artist, an award almost everyone had thought would go straight to Justin Bieber. Spalding was the…

“Now you can go out to eat and that's for sure/ But it's nothin' a homegrown tomato won't cure/ Put 'em in a salad, put 'em in a stew/ You make your very own tomato juice.

"You can eat 'em with eggs, eat 'em with gravy/ Eat 'em with beans, pinto or navy/ Put 'em on the side, put 'em in the middle/ Put a homegrown tomato on a hotcake griddle

"Homegrown tomatoes, homegrown tomatoes/ What'd life be without homegrown tomatoes/ Only two things that money can't buy/ And that's true love and homegrown tomatoes.”…
