Red Wine Audio announces Signature 57 integrated amplifier


What I dig most about Red Wine Audio’s battery powered approach is that the end-user doesn’t need to spring big for deluxe power chords, power filters/regenerators and the like; this is one of the many reasons why the Signature 15 integrated netted a DAR-KO award last year.

Chief sommelier Vinnie Rossi has been touting his high-end Signature 57 integrated at shows for most of 2013 and now he’s finally ready to formally announce its availability.

At its core sits Red Wine Audio’s LifePO4 battery technology that brings 12-18 hours of off-grid listening from a single charge. Under the hood, “a discrete Class AB MOSFET” design that pushes (you guessed it) 57 wpc into 8 ohms and 115 wpc into 4 ohms (hello Magnepan MMG); the Signature 57 will cope with 2 ohm loads/dips meaning those with more challenging speakers aren’t left out in the cold. Imagine a pair of Red Wine Audio’s Liliana mono blocks locked under one roof.


The Signature 57 is an integrated amplifier with integration on its mind. Users can opt for the Isabellina Pro DAC and/or Analogica phono boards as internal add-ins. The Cassabria’s single-ended headphone output is also an option.

“Combining these products into one enclosure not only saves the customer a lot of money compared to buying them separately, it also eliminates the added expense of interconnects and chargers associated with separate components — making for a true all-in-one high-end listening experience.”, says Rossi.

The Signature 57 base unit has four analogue inputs and is available in cherry, maple and walnut finishes. It will sell for US$3995.


Additional module pricing is as follows:

Isabellina Pro DAC – add $1500
Analogica phono stage – add $1000
Headphone amplifier stage, single ended – add $500

This could be just the ticket now that Peachtree Audio have decided to discontinue their Grand Integrated amplifier.  I’ve got a Signature 57 coming this way for review so stay tuned.

  1. Dear John,

    I’m a big fan of Digital Audio Review. Thank you for all your hard work and passion for hi-fi. I feel fortunate to be on the receiving end of all that you do. I have learned so much from your website and always look forward to your posts.

  2. I’m also looking forward to your review on the Red Wine Audio Signature 57. I own a pair of Magnepan SMGA’S and I’m currently searching for an integrated amplifier that will be a synergistic match for these classic speakers.

  3. Red Wine Audio products are very nice looking and well sounding although they are very overpriced. I used to have Isabellina Pro DAC ($1500) and it was very nice, but neither me or my audiophile friend couldn’t see any improvement in sound quality in comparison to even $300 DACs. They same I’ve heard from people on the audio forums who discussed RWA Pre-amp. The price/quality ratio is unfortunately very poor.
