– Exceptional. Running a Fender Precision Bass with flats through the -HBAD-150- into a Neve preamp, the attack of the fingerstyle was preserved without the “splat” that cheaper active DIs add. The high-end extension is remarkable: an acoustic guitar’s pick noise and string harmonics felt present but never harsh. Piano and synth lines (tested via a Nord Stage 3) retained their stereo image when using two units—though the -HBAD-150- is mono, so buy a pair.

For re-amping, the -HBAD-150- is a godsend. The thru jack can send a clean signal to your DAW while the XLR feeds an amp. The ultra-low distortion means you can capture a pristine DI track for later processing. Compared to a Universal Audio Apollo’s built-in DI, the -HBAD-150- had slightly better transient detail and a blacker noise floor (-129dBu EIN).

– Unlike the vintage “color” of a Jensen or Cinemag transformer in passive DIs, the -HBAD-150- uses a custom-wound, wide-bandwidth transformer with active drive. The result is nearly invisible. No low-end roll-off, no midrange smear. If you want character, add it later with a preamp or pedal. If you want a wire-with-gain, this is it. However, some engineers might find it too clean for electric guitar, preferring the passive JDI’s slight low-end thickening. – Exceptional

The Neutrik-compatible jacks are recessed slightly to prevent accidental pull-out, and the XLR output is a locking type with gold-plated pins. The switches—Ground Lift, Pad (-15dB / -30dB), and Polarity Reverse—are heavy-duty, toggle-style with a satisfying, tactile click. No cheap plastic rockers here. The LED indicator for phantom power presence is a subdued white (not the usual blinding blue), a thoughtful touch for dark stages. Piano and synth lines (tested via a Nord

The -HBAD-150- wins on headroom and transparency but loses on price if you don’t need the extra headroom. For most guitar/bass players, the JDI’s color is more flattering. For keyboardists, synth nerds, and studio engineers, the -HBAD-150- is superior. No unit is perfect. After two weeks, I noticed a faint ticking noise (around -90dBu) when using a dying 9V battery (below 7V). This is common in active DIs, but the spec sheet claimed it would shut down cleanly below 6V—it didn’t. Workaround: change batteries often or use phantom power.
