According to Audio Research:
"The LS27 not only offers remarkable resolution, musicality and dynamic impact, it is our most flexible line-stage and able to adapt to most any situation. In terms of control options, the LS27 has selectable High / Medium / Low gain settings for each input, BAL / SE input selection, Left-Right Balance control, Invert (phase), and Stereo / Mono selection. Tube hours can be monitored, there is a Processor pass-through for home theater applications, and the display is dimmable with the option of being turned off. All of the inputs and outputs have balanced XLR and single-ended RCA connectors, including six pairs of discrete inputs, a processor (unity gain) input, a monitor loop, and two sets of main outputs. A new microprocessor controls all functions. The rear panel also includes a 12V trigger and a 15A IEC connector.
The LS27 is a pure Class-A design with zero feedback, and the massive power supply is fully regulated. Gain is provided by twin 6H30 triodes. Multiple circuit changes and refinements account for greatly improved performance, including bulk power-supply storage that has been substantially increased, a new power transformer, and costly new output and bypass coupling capacitors that bring new dynamic life and even more refinement to the presentation."

According to Absolute Sound:
"It’s a truly great piece of equipment. It has an ability to disappear in the way all good preamps are supposed to do, and does so with outstanding image size and width. That means it’s resolving enough to highlight details in changes elsewhere up-stream, yet does not lay the sound so analytically bare as to devastate the chances of it ever sounding good. It’s been some time since I reviewed an ARC preamp and it’s clear the performance has moved ahead several notches since last I set my system’s watch to Minnesota time. ...we are living in a golden age of audio. We need to stop living in the past; this current crop of products sound better in some very fundamental ways to any of the sacred cows of the past. In valve world, it gets no better than this."

According to SoundStage! Hi-Fi:
"...the Audio Research LS27 is one of the very best preamps I have had in my system. The LS27 will thrill most audiophiles. It raises the bar for what should be expected from a preamp in its price class.
