USED - Parasound Halo P6 2.1 Channel Preamplifier & DAC - Silver

The 2.1-Channel Command Center

Most stereo preamps ignore the subwoofer, leaving bass management to chance. The Parasound Halo P6 makes it a headline feature: a true 2.1-channel preamplifier with analog high-pass and low-pass crossovers, three subwoofer outputs, and a front-panel sub level knob. Add a reference DAC, a real MM/MC phono stage, and a proper headphone amplifier, and the P6 becomes the connection hub an entire system is built around.

The converter is an ESS Sabre32 Reference DAC (ES9018K2M) fed by asynchronous USB, playing PCM up to 32-bit/384kHz and native DSD256, with coaxial and optical inputs handling sources up to 24-bit/192kHz. The phono stage accepts moving-magnet, moving-coil, and moving-iron cartridges with 38dB or 52dB of gain and selectable 47k-ohm or 100-ohm loading. Volume runs through a resistor-ladder control for precise, channel-matched tracking.

Line sources get five RCA inputs plus a balanced XLR pair, and a front-panel aux input welcomes whatever visits.

Bass Management Done the Analog Way

The P6's crossovers work in the analog domain at 12dB per octave: the high-pass filter relieves your main speakers of deep bass, while the low-pass sends it to your sub through balanced XLR or twin RCA outputs. Speakers play cleaner, the subwoofer does what it's built for, and the whole system gains headroom.

A home theater bypass input lets the P6 share front speakers with a surround processor, and bass and treble controls with true relay bypass stay out of the signal path when unused. The headphone output runs a high-current Texas Instruments TPA6120A amplifier. Everything answers to a backlit remote, 12-volt trigger, and IR jacks for custom installs, and Parasound backs it with a 5-year parts and labor warranty.

What Reviewers Are Saying

Michael Zisserson of Future Audiophile, in a January 4, 2023 review, wrote: "The Halo P 6 preamplifier can do it all when it comes to a preamp... the Halo P 6 is truly a hard-to-beat value," adding that "the DAC in the Halo P 6 alone is worth the... selling price." His one gripe: "The remote feels a little chintzy."

The Audio Tailor, in a July 16, 2025 review, praised the "industry-leading ESS Sabre32 DAC" for delivering "breathtaking detail and dynamics," noting the P6's "dynamic range soars well beyond 120 dB."

Who Is This Preamplifier Best For?

• You run a subwoofer, or two — real analog bass management is the P6's signature advantage.
• You have sources of every kind — vinyl, digital, computer, and line-level all get first-class inputs.
• Your system doubles for movies — home theater bypass integrates a surround processor cleanly.
• You want balanced connections — XLR input and outputs feed power amps the quiet way.
• If you want streaming built in, the P6 has no network input — a HiFi Rose RS451 combines streamer, DAC, and preamp in one.

How Does It Connect to Your System?

Connect the balanced XLR or RCA outputs to your power amplifier and your subwoofer to the dedicated sub outputs, then set the crossover and level from the front panel. Your turntable joins the phono input with the loading switch matched to your cartridge, your computer connects by USB, and disc players use coax or optical. A surround processor plugs into the bypass input for movie nights.

One box, every source, and bass finally managed instead of merely present.

Frequently Asked Questions

What does "2.1 channel" mean?

Stereo plus subwoofer, managed properly: analog crossovers split bass to the sub outputs while your main speakers play the rest.

What DAC is inside?

An ESS Sabre32 Reference ES9018K2M, playing PCM to 32-bit/384kHz and native DSD256 over USB.

Can I connect a turntable?

Yes. The phono stage handles MM, MC, and MI cartridges with 38dB or 52dB gain and selectable loading.

Does it work with a home theater?

Yes. The bypass input lets a surround processor share your front speakers and subwoofer.

Does it have a headphone output?

Yes, driven by a high-current Texas Instruments TPA6120A headphone amplifier.

What warranty does it carry?

Parasound covers the P6 with a 5-year parts and labor warranty.
