Burl Audio B2 Bomber DAC – mastering-grade two-channel digital-to-analog converter, with a discrete Class-A output stage and an optional output transformer.
Conversion runs at 24-bit resolution across sample rates from 44.1 kHz to 192 kHz, with an output built around fully discrete BOPA11 chips and passive filtering rather than the active digital filters typical of converters designed purely for neutrality. Digital inputs - AES/EBU, S/PDIF, and Toslink - are selected directly from the front panel, and the clock can be synced internally or externally through a BNC word clock connector with switchable 75 ohm termination. A six-position audiophile stepped attenuator and a switchable output level (+14 dBu or +28 dBu) let the DAC match any monitoring chain without losing metering precision.
Passive filtering and zero capacitors in the output path
Replacing active digital filters with a passive design, and eliminating capacitors entirely from the output path, limits the number of components that could add their own sterile coloration typical of converters engineered purely for linearity. In practice that means a more three-dimensional stereo image and a clearer low-end foundation during reference listening, which matters when making mix and mastering decisions based on what's actually heard on the monitors.A switchable output transformer for extra saturation
The optional BX2 output transformer adds an alternate tonal character at the flip of a switch, introducing the harmonic saturation typical of classic analog paths without routing the signal through a separate external device. That setup lets you quickly compare a transparent, transformerless path against a warmer, more colored tone within a single unit, depending on the material and the stage of the work.KEY FEATURES
