Compact Tube Preamp with MM Phono

The LORDWORLD H5 is a new stereo preamplifier that adds tube warmth and MM phono capability to a compact HiFi system. It suits listeners who want vinyl playback, tone control, and subwoofer integration without a full-size component rack. It is not for buyers who need balanced XLR connections, moving-coil phono support, or multi-channel home-theatre processing.

MM Phono Input with 20 Hz High-Pass Filter

The single specification that decides fit is the MM phono stage paired with a 20 Hz high-pass filter. This combination accepts moving-magnet turntables directly while suppressing low-frequency rumble that can muddy playback. Systems relying on moving-coil cartridges or line-level sources alone will not use the phono stage.

Dual RCA and SUB Outputs with 180/250 Hz LPF

Under sustained use the dual RCA outputs drive two amplifiers or powered speakers simultaneously, while the SUB output applies a selectable 180 Hz or 250 Hz low-pass filter to blend a subwoofer cleanly. Shielded tube power, a fourth-generation relay, and a socketed 5532 op-amp keep noise low during long listening sessions.

Questions about this item

How does the 20 Hz high-pass filter affect vinyl playback?

The 20 Hz high-pass filter removes subsonic rumble from warped records or turntable motors, keeping playback steadier and protecting downstream speakers from excessive cone movement.

What does the SUB Out low-pass filter do at 180 Hz and 250 Hz?

The selectable 180 Hz or 250 Hz low-pass filter on the SUB Out limits bass sent to a subwoofer, reducing overlap with main speakers for tighter, better-integrated low frequencies.

What tube type and drive voltage define the preamp's core sound?

The unit is tuned around GE-4BZ6 tubes running at 180 V plate voltage, delivering smooth warmth, rich midrange body and natural analog depth for vocals, jazz and vinyl.
