The Red Wine Audio Signature 30.2 stereo amplifier 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 stereo 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.

With the SMART module, any user concern of accidentally damaging the internal SLA batteries by forgetting to turn off the Signature 30.2 is eliminated!

“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.”

“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.”

Like a Finely-Tuned Instrument...

The Signature 30.2 stereo amplifier is a highly refined and improved version of our award winning Signature 30.
Listed below are the major refinements in its musical presentation: :

• a) A warmer, and more seductive sound signature

• b) Greater dimensionality

• c) Added bass weight

• d) Sweeter top end

• e) Richer tone, without sacrificing any pace, rhythm and timing

The amplifier board in the Signature 30.2 has been heavily modified in order to achieve the sonic enhancements listed above. Below are examples of such refinements:

1. A new output filter stage design that features all new, higher-quality components as well as all new filtering characteristics.

2. The new output filter components are now hard-wired together (point-to-point) and have the speaker output wiring directly connected to them to offer an even shorter, cleaner signal path.

3. A higher grade of PIO (paper-in-oil) input capacitor

4. Modified input stage design, which also features higher quality parts such as resistors, dc offset pots, etc.

Also featuring:

* Custom “touch-sensing” power on/off switch with built-in LED that emits a soft, red glow. This switch is mounted flush with the black-anodized aluminum front panel for a clean appearance and is also made of smooth, black-anodized aluminum.

* Black, powder-coated aluminum enclosure with a smooth, 0.5” thick black-anodized faceplate that is laser-etched. Silver-painted, machined aluminum knob (available with Signature 30.2 stereo amplifier with integrated precision stepped attenuator volume control with remote)

* Premium input and output jacks by Vampire

* Rapid-speed SLA battery charger with universal input voltage (100 – 240Vac, 50/60Hz) and IEC power input jack, and output cable featuring a heavy-duty XLR plug

Warranty

5-years for any manufacturing related defects (parts and labor included)

The SLA batteries are not covered under the warranty because we have no way of knowing how they were taken care of. Opening the enclosure for any reason other than replacing the batteries (as outlined in the included owner's manual) will VOID your warranty
