User reviews and community discussions on the Puritan Audio Labs PSM156 AC Distribution reveal a polarized reputation: audiophiles praise its noise reduction and sound improvements, while objective measurements highlight filtering limitations and no audible audio benefits.
### Sound Quality
- Many reviewers report enhanced clarity, focus, authority, and soundstaging, with reduced noise floor creating a "deeper black background" and better detail retrieval across frequencies.
- It eliminates buzz, hiss, and transformer hum in some systems, making music "flow" with retained dynamics and vigor.
- Drawbacks include potential loss of dynamics, slam, liveliness, fullness, and excitement when powering amps, sounding more "delicate and lean" at low volumes.
- Objective tests show no improvement in THD+N or distortion (identical to direct mains), with effective filtering only above ~500 Hz and resonances adding noise.
### Build Quality
- Consistently praised as sturdy, compact, and well-engineered with a "stout and serious" black chassis, massive outlets with auto-closing lids, super thick yet flexible 20A cord, and individual filtering per six outputs.
- Minor issues: floating grounding lug with sheared screw in one unit.
### Reliability
- Handles common-mode/differential-mode noise and DC offset effectively for its price, with no widespread failure reports; users describe it as "solid" and a "complete package".
- Measurements note vulnerabilities: DC increases distortion, high-frequency noise leaks between outlets (contradicting individual filtering claims), and added bumps (40-50 kHz) at amp outputs.
### Strengths
- Excellent high-frequency filtering (up to 57 dB at 20 kHz, better than competitors like AudioQuest Niagara).
- Noise reduction for digital components and systems with interference; "worth its weight in gold" for clean power delivery without "stifling".
- Value at ~€1740: pragmatic, no "fluff," stays in systems long-term.
### Weaknesses
- Ineffective below 500 Hz, no overall audio fidelity gains in blind tests; may add noise or fail to block contamination.
- Can reduce dynamics with power amps; inconsistent hum reduction in tubes.
### Overall Reputation
- Highly recommended by enthusiasts and reviewers for practical mains cleaning ("exciting discovery," "NEVER sell," "powers everything dead quiet/neutral").
- Skeptical in measurement-focused communities: good general filter but not for audio improvement; "can't recommend" as fidelity enhancer.
- Strong consensus on build/value, divided on sonic benefits depending on system and expectations.

The fair market price for a Puritan Audio Labs PSM156 AC Distribution (standard model) in AUD is approximately $3,800–$4,800, based on recent USD listings converted at a conservative 1.50 AUD/USD exchange rate (reflecting 2025–2026 market conditions).
### Price Range Breakdown
| Condition | Typical AUD Range | Key Listings (Converted from USD) |
|-----------|------------------|-----------------------------------|
| New | $3,800–$4,800 | $2,495 , $2,500 , $2,700 , $3,300 |
| Used | $3,200–$3,600 | $2,400 sale price |
Prices vary significantly by condition, with new units commanding a 20–30% premium over used due to warranty (typically 5 years) and original packaging. Special editions (e.g., PSM156 SE or PSM156+) list higher at ~£2,100–£2,150 (~$4,000–$4,300 AUD) or up to $3,500 USD (~$5,250 AUD), but these are distinct variants with upgraded sockets.
### Key Factors Affecting Value
- Region/Market: Higher in Australia/North America ($2,500–$3,700 USD) vs. UK origin (£1,450–£1,550 or ~$3,400–$3,600 AUD).
- Accessories: Bundled 2m power cord adds ~$150–$200 AUD value; upgrades (e.g., rack mount, custom cables) increase by $150–$500.
- Variants: Standard PSM156 (52 filter stages, 6x15A outlets) vs. SE/+ models with premium components.
- Demand: Hi-fi audio niche drives premiums for low-noise power purification; open-box deals dip 15–20%.
Estimates are conservative, prioritizing recent retailer listings over older reviews (e.g., 2023). Actual sales may fluctuate with AUD/USD rates, shipping (~$100–$200 AUD), and local taxes.
