Outwardly, the 80S shares the same dimensions as the 160M. A single shallow whisper fan is built into the bottom plate. Flexibility is built-in, too, with XLR and SE inputs, 4-8-16 ohm output taps, 12V input and output triggers, RS232 input, tube hour meter, switchable fan speeds, and defeatable auto-off function. The feature set is the same as the 160S, including a proprietary auto-bias ci...[more]

Reference 160M Vacuum tube Monaural power amplifier After two years in development, the new Reference 160M (REF160M) Monoblock Power Amplifier is built like no other, looks like no other, and sounds like no other amplifier that you have ever heard, but it is unmistakably Audio Research. It features a refined audio topology with fewer and better components in the signal-path than in pr...[more]

Relentless Monoblock Amplifier Dan D’Agostino has always had a relentless desire to better his own creations, no matter how flawless they may seem. The Relentless Monoblock amplifier is the latest manifestation of that passion, the result of Dan’s desire for an amplifier that maintains its harmonic integrity and expansive soundstage from 0 watts to 1,500 watts. An amplifier so pow...[more]

Every major section of the Relentless Epic Mono Amplifiers- power supply, input, driver, and output stages - have all been enhanced in this advancement.  A new power management topology further isolates the power supply from the entirety of the audio circuitry providing extra protection from the noise the massive power transformers can generate. The Relentless Epic and Epic 800 employ ...[more]

Perfect Balance and Absolute Fidelity Crucial to the new circuit are the bipolar transistors powering the front end of the amplifier.  Activating the driver stage is a new bias stability circuit providing a nearly 50% increase in operating bias. Increasing Class A operation directly correlates to better sound quality. With this new circuit topology and the unique Copper/Aluminum heatsi...[more]

With its 5.5-kilowatt power supply feeding nearly 100 output devices, the Relentless Mono  Amplifier easily delivers 1,500 watts into 8 ohms—and when connected to a 220-volt or greater AC mains outlet, it doubles its output to 3,000 watts into 4 ohms and 6,000 watts into 2 ohms.  This power output is maintained with the same musical composure at full power as it is at 1 watt. ...[more]
