I am new here but am also on USAM, Audiogon, Ebay etc. I have perfect ratings on all of them. Ask if you would like to see my history there
If you are near Sacramento, I am happy to audition before purchase. I am also willing to drive an hour or two to meet somewhere.
Very conservatively rating this as an 8/10 only because I am the second owner. No nicks, scrapes or scratches and works perfect.
There are plenty of videos on youtube talking about this amplifier.
The Parasound Halo A21+ delivers commanding power with effortless musicality. At 300 W per channel into 8 Ω (500 W into 4 Ω), and up to 1,000 W bridged, it drives any loudspeaker with authority while keeping the sound spacious, controlled, and fatigue-free.
Based on legendary John Curl’s circuit design, the A21+ refines Parasound’s most celebrated power amp for today’s systems—blending raw performance with elegant simplicity. Balanced XLR and RCA inputs, 2 Ω stability, and flexible bridging make it an ideal match for both stereo and home theater setups.
Praised by audiophiles and reviewers alike:
“The soundstage just bloomed. Bass is crisp… mids and highs are singing.”
“Ridiculously high damping… bass is tight and controlled at all volumes.”
“Delightful and satisfying from the first note… impossible to fault.”
