We offer both single-ended and balanced headphone stages

The single-ended output brings your music to life with fine resolution, lifelike soundstage, and natural timbre & tone. And for your hard-to-drive headphones, the balanced headphone stage offers all the sonic goodness of our single-ended stage — plus it delivers more power and stunning dynamics.

Single-ended headphone stage…

  • Delivers a highly-resolved and seductive headphone listening experience
  • Couples warmth and tone, while uncovering subtle details and delicate spatial cues
  • Uses a 6.35mm (1/4") stereo headphone jack on front panel
  • Is powered by the LFP battery pack inside your unit, delivering an ultra-quiet background

The single-ended headphone stage comes standard on our Cassabria headphone amplifier, and is offered as a factory installed option on select Red Wine Audio components.

Balanced headphone stage…

  • Drives a wide range of headphones with ease
  • Brings music to life with stunning dynamics, fine resolution, lifelike soundstage, and natural timbre & tone
  • Features a high-current, discrete FET design that delivers a clean 5 watts RMS into 32-ohms
  • Uses a Neutrik 4-pin XLR output jack on front panel
  • Is powered by the LFP battery pack inside your unit, delivering an ultra-quiet background

The balanced headphone stage comes standard on our Cassabria headphone amplifier, and is offered as a factory installed option on select Red Wine Audio components.

We offer two levels of DAC support...

Red Book conversion via our tried-and-true 16-bit, NOS Bellina design. Or opt for Bellina Pro and you can choose between our traditional 16-bit DAC and high-resolution 24/192k playback, by simply flipping a switch. And if you're a computer-based audiophile, be sure to check out our advanced USB techologies.

Features
  • 3 inputs: Coaxial, Optical and USB
  • Red Book (NOS 16-bit) playback ships as base-level Bellina DAC
  • Class-A FET I/V conversion stage (no opamps used)
  • USB input eliminates need for S/PDIF conversion, a sound-degrading step found in many USB DACs

  • USB input isolates your computer’s power bus from the internal DAC chip — an innovation called “galvanic isolation” — preventing computer noise from degrading the sound



The 16-bit Bellina DAC comes standard on Bellina and Bellina HPA, and is offered as a factory installed option on select Red Wine Audio components. Bellina Pro is an upgrade option to our 16-bit Bellina DAC, and is offered as a factory installed option for all products supporting our Bellina DAC.

Optional Bellina Pro

Two digital-to-analog chips on a single board. One optimized for high-resolution playback. One optimized for Red Book playback.

  • Red Book conversion via our tried-and-true 16-bit, NOS Bellina design
  • High-resolution conversion via premium 24/192k Wolfson DAC chip
  • Toggle between the two d/a converters by simply flipping a switch
  • High-res converter also plays 16-bit, so you can choose between two sonic "flavors” when listening to Red Book
  • Supports 44.1, 48, 88.2, 96, 176.4, and 192k via coax and optical inputs (more on USB below)

Bellina Pro Advanced USB Support

For computer-based audiophiles, Bellina Pro features advanced technologies bringing sonic improvements to both Red Book and high-resolution playback via USB...

  • Asynchronous mode USB-to-I2S conversion (USB 2.0 compliant)
  • Integer-mode compatible
  • Supports 44.1, 48, 88.2, 96, 176.4, and 192k files (no driver required for Mac OS X)

State-of-the-art technology. Delivers improved sound & added convenience compared to alternative battery types.

LiFePO4 (LFP) battery packs have much lower internal resistance (compared to SLA), which translates directly into better sound. And only Red Wine Audio offers premium LFP battery packs for an entire line of hi-fi components, resulting in:

  • Great dynamics
  • Tight, resolved bass
  • An open and extended treble response
  • The most environmentally friendly battery technology available
  • 5 times the cycle life compared to sealed lead-acid (SLA) batteries
  • No loss in cycle life when batteries run to complete discharge
  • Built-in, custom-designed cell management, optimizing battery performance and reliability
  • Ease of replacement, with no special skills or soldering required

Adds richness and warmth. Standard on most components.

We’re the first company to combine tube richness and warmth, with a level of purity only LiFePO4 battery power can deliver, and make it available across an extensive line of audio components, delivering:

  • A large 3-dimensional soundstage
  • Lifelike harmonics and tone
  • Outstanding retrieval of subtle detail
  • The blackest background achievable using tubes
  • An emotionally involving, “toe-tapping” listening experience
  • Ability to fine tune the sound, via tube rolling, to match your system needs and musical taste

Features

  • New on-board switch allows choice of 6922 or 12AX7 families of tubes, for added flexibility in tube rolling
  • New addition of polystyrene bypass capacitors provides more open and nuanced top-end response
  • Operates in Class-A mode, delivering the highest level of sonic purity
  • Delayed turn-on sequencing mutes audio signal while tubes warm up,  avoiding turn on / off “pops”
  • Maximizes tube life by heating them prior to applying plate voltage
  • “Buffered-design” via high input impedance and low output impedance, breaths additional life into your music
  • Auto-biasing for tubes – so just plug ‘n play!

Accepted Tubes

6922 / E88CC, 6DJ8 / ECC88, 7308 / E188CC, 7DJ8 / PCC88, 6N23, 6H23, 6N11, and 6GM8

Fully automates all aspects of battery management. AC power can be totally absent from signal path, for better sound.

Our innovative SMART board (Seamless battery Monitoring and Auto Recharge circuiT) continuously monitors battery pack voltage. When voltage drops to predetermined level, SMART turns your unit OFF and begins charging. When charging is complete, the external charger can remain connected indefinitely. It’s that simple!

  • New 3-position front-panel rotary switch provides added convenience when selecting one of three operating modes:

    1. OFF and charging
    2. ON while charging at the same time, for unlimited play time
    3. ON in “Pure Battery Mode,” where both positive and negative leads of battery charger internally disconnect from battery (so there’s zero chance of sound degradation)

  • In-rush current limiting provides your unit with soft starting, maximizing component lifespan
  • External battery charger to completely eliminate internal AC noise

Our new Renaissance Edition enclosures fuse traditional with new design elements, resulting in a timeless, organic look.

Choose between natural maple, rich walnut or warm cherry solid-wood front & side panels — each crafted & finished by hand, and protected by multiple coats of polyurethane. We also hand-sand between coats to produce a smooth and enduring finish.

  • 1/2" thick, solid-wood front and side panels*
  • Laser engraved front panels
  • Chrome plated, solid aluminum knobs
  • Red LED "power-ON" indicator above the mode select knob
  • Black, powder-coated top plate with Red Wine Audio logo ventiation holes - provides easy access to inside of unit by simply removing a few thumb screws

    * Wood side panels only available for units that do not have side heatsinks  

Personal pride is evident in every component we build. Our products:

  • Are designed and built by hand in the USA
  • Incorporate premium parts throughout like discrete FETs vs. lesser sounding (and less expensive) op amps
  • Feature purist circuit designs, including short and direct signal paths
  • Run 'off-the-grid' on pure LiFePO4 (LFP) battery power, eliminating the AC-to-DC conversion process when listening
  • Are built to last, and backed by a comprehensive 10-year warranty and highly personalized service

Referencing Red Wine Audio’s Isabellina HPA DAC/headphone amp, this is the question Steve Guttenberg poses in CNET News. But, Isabellina HPA LFP-V Edition owners already know the answer.

“I’ve reviewed and auditioned a lot of headphone amplifiers over the years, but Red Wine Audio’s Isabellina HPA LFP-V Edition stood out from the pack… It sounds remarkably pure, detailed, and clean, but without any false clarity.”
“…acoustic music sounded a giant step closer to the way it does in real life…”
“… Isabellina sounded more like live music.”
