Parasound Halo P6 Preamplifier

Drop the Halo P6 into your rack and everything snaps into focus. Voices feel present, bass blends cleanly with your sub, and streaming loses the edge that keeps you from turning it up. Vinyl clicks. Long sessions get easier, and every source just sounds more like music.

Designed as a true 2.1‑channel control center, the P6 adds the pieces most systems are missing: an ESS Sabre32 Reference DAC (ES9018K2M) with USB up to 384 kHz/32‑bit and native DSD64/128/256, coax/optical 192/24, fully analog bass management with independent high‑pass/low‑pass crossovers and front‑panel sub level, MM/MC/MI phono (100 Ω or 47 kΩ), balanced XLR input, balanced & RCA pre‑outs, plus XLR + dual RCA sub outs. It also uses a resistor‑ladder volume control for fine, low‑noise steps, includes a high‑current TI TPA6120 headphone amp, and offers Home Theater Bypass for seamless 2‑channel + surround integration. 

Praised by audiophiles and reviewers alike:

• “The P 6 is a wonderful listen.” — Positive Feedback.
• “The Halo P 6 preamplifier can do it all when it comes to a preamp.” — Future Audiophile.
• “…the P 6 is a no‑brainer for anyone shopping for a digitally enabled preamplifier close to its asking price.” — Home Theater Review.
