Signature 30.2 Stereo Amplifier

Signaturesm Buy302ampOffered as both an integrated stereo amplifier and two-channel power amplifier, Red Wine Audio’s Signature 30.2 was created for music connoisseurs seeking a sublime listening experience, dependability and value.

Carefully designed to deliver a well-balanced musical presentation and long-term listening pleasure, the Signature 30.2 amplifier combines the finest sonic attributes of classic tube amplification (midrange warmth, rich tonal character, and smooth high-frequency resolution) and solid-state amplification (rock-solid bass response, realistic dynamic range and clarity) to enhance the listener’s emotional involvement with the music.

As with all Red Wine Audio products, the Signature 30.2 stereo amplifier is powered by clean, high-current sealed lead-acid (SLA) batteries that allow all the nuances of the music to emerge with remarkable coherence and integrity. By running on internal SLA battery power and isolating itself from the AC power grid, the Signature 30.2 stereo amplifier is free from the entire AC to DC conversion process and the associated electrical noise problems that hinder the performance of conventional AC-powered amplifiers.

On the inside of the Signature 30.2 stereo amplifier is a unique circuit design that demonstrates our beliefs in using premium parts, shorter signal paths, and SLA battery power. On the outside you will enjoy elegant aesthetics and superb build quality. Every Signature 30.2 stereo amplifier is proudly hand-made in the USA and carefully tested, inspected, and packaged before making its journey to our highly-valued and satisfied customers.

The Signature 30.2 stereo amplifier features a Red Wine Audio innovation… the SMART module (SLA battery Monitoring and Auto Recharge circuiT). This is a custom-designed circuit board that continuously monitors the voltage of the internal SLA batteries. If the voltage drops too low, the SMART module automatically turns off the Signature 30.2 and begins the battery recharge process for you.

Reviews

“Minimalist to the core, with top-notch parts and a deeply tweaked circuit, this amplifier has already sidelined $45,000/pr battery-powered monos, given $10,000/pr muscle amps the fly-bye finger and butted heads with first-rate tube amps. I’ll tip my hand and reveal prior to the full review conclusion that the 30.2 will walk away with a Lunar Eclipse Award in the new year, only the fourth one to be given out in our 5 years of operation.”

Lunar Eclipse Sig 30.2

“Red Wine Audio’s Signature 30.2 is one of my three favorite amps regardless of class or output devices… it sonically goes well beyond its own first incarnation to have turned into a bona fide ultrafi amp that’ll upset equilibrium in the upper ranks of overpriced eye candy for those who pay attention and evaluate with their ears.”

Srajan Ebaen, 6moons.com

“Truly a sonic tour-de-force and NOT just at the price. This may be the finest all-around integrated I”ve heard.”

David Abramson, Stereo Times

“The 30.2 offers one of the most musical presentations at this price point… the 30.2 delivers the goods!”

Jeff Dorgay, TONEAudio [1.3mb PDF]

“Of all the amplifiers that I’ve tested in recent years, the Signature 30.2 is one of the best. Period.”

Gary Krakow, TheStreet.com

“Elegantly simple, functionally flawless and sonically whole, I couldn’t pass this one by. At the price, it strikes me as an utter sonic triumph and serves to remind me daily that different isn’t always better, though sometimes it very definitely is!”

David Abramson, Stereo Times
