Red Wine Audio Upgrades to New Battery Technology

Red Wine Audio have just introduced a major upgrade for all their components.

The upgrades are twofold:

    Replacement of SLA batteries with new LiFePO4 Battery technology
    Addition of Tube buffer stages

The advantages of the new LiFePO4 Battery technology are as follows:
The new “Lithium Iron Phosphate” (LFP) battery technology provides greater performance, safety, reliability and environmental friendliness than any other rechargeable battery technology.

New LFP battery technology pack

These LFP battery packs are manufactured exclusively for Red Wine Audio.

    Improved sonic performance and extended “off-the-grid” listening sessions.They are designed to be cycled (discharged and recharged) over 5x more than their SLA counterparts, resulting in significantly improved battery life.

    Complete discharging does not reduce their overall life as it did with SLA batteries.

    Ability to enjoy continuous play time, even while the battery pack is charging (simply by flipping a switch)

    They are 1/2 the size and 1/3 the weight of SLA batteries.

    They are user-replaceable: (no soldering required)

Changing to this advanced battery technology has enabled Red Wine Audio to add a Tube buffer stage to all of their products. Based on the same 6922 (or equivalent) tube as used in their award winning Isabella pre-amplifier.

The LFP battery technology is the cleanest and purist way to power a tube buffer stage. Now the Signature 30 and 70 series of volume controlled or fixed gain power amps are all improved by the sonic benefits of this tube power stage.

Obviously the Isabella already employs the 6922, so upgrades to the Isabella only involve the change over to LFP battery technology and the smart charging board.

Upgrade prices differ by component, though are approximately $1000 (€790) per component.

All Red Wine products will incorporate these improvements going forward.

We will arrange upgrades for existing Red Wine Audio products. The demand for these is high and currently backdated to November, so the sooner you arrange the upgrade through us the earlier it will be completed.
