Here’s an overview of the Best Power Conditioners that we’ll explore today:
Power conditioners and surge protectors are more than cable organizers; they shield sensitive audio-video and computer gear from the vagaries of the electrical grid, RF/EMI noise, and dangerous voltage events. In this review, I test and compare five widely available models across a price spectrum from budget to premium to illustrate how features like SMP technology, LiFT filtering, auto-reset voltage protection, and rear-panel outlet layouts translate into real-world value. My methodology combines objective spec analysis, build quality assessment, and practical testing in a controlled environment: load tests with typical home theater and studio gear, EMI/RFI behavior observation, and life-cycle considerations like ease of use and maintenance. The lineup covers Furman options that emphasize premium protection and filtration, plus a Pyle model that expands the budget category.
1. Furman Power Conditioner (SS6B) black
- Brand: Furman
- Manufacturer: Furman
Overview: The SS6B is Furman’s compact, budget-friendly power conditioner with a 6-outlet block, 15-foot power cord, a circuit breaker, and EMI/RFI noise attenuation wrapped in a heavy-duty metal chassis. It is a straightforward, no-frills protector designed to clean up common household noise without elaborate diagnostics. At $34.80, it sits squarely in the value tier and inherits Furman’s lineage of reliable surge suppression and basic power conditioning. Prospective buyers get a durable, simple unit that improves basic hum and buzz from consumer electronics while offering visible, illuminated ON/OFF feedback for quick status checks. Consistency of build is solid for the class, but it lacks advanced protections or filtering sophistication found in higher-end Furman models.
Performance-wise, the SS6B delivers standard EMI/RFI attenuation and 125V operation with six outlets, which is sufficient for a typical home entertainment setup or a small recording rig. It uses Furman’s reputation for rugged construction, and the 15-foot cord adds flexibility for room layout. However, there are no auto-reset protections or voltage monitoring features, making it less ideal for devices that require proactive protection in fluctuating environments. The unit excels as a starter-level conditioner that provides basic surge protection and clean power, while remaining a sensible budget purchase.
Pros
- Very affordable entry point with Furman heritage

2. Furman AC-215A Compact Power Conditioner with Auto-Resetting Voltage Protection – Black
- Brand: Furman
- Manufacturer: Furman
Overview: The AC-215A represents Furman’s compact, feature-rich option with Auto-Reset EVS (voltage protection) and LiFT (linear AC power filtering), designed for home theater, studios, and pro audio setups where voltage irregularities and power quality are critical. At $149.00, it targets users who want higher protection density in a compact footprint, making it a strong choice for plasma/LCD TVs, projectors, and home recording gear. Prospective buyers gain Furman’s premier protection ecosystem in a small chassis with an integrated auto-reset mechanism to shut down safely during dangerous conditions, preserving equipment without manual intervention.
In practice, the AC-215A’s LiFT filtering provides cleaner AC delivery by reducing noise across relevant frequencies, which translates to crisper audio and more stable video. The auto-reset EVS circuitry detects dangerous voltage irregularities and powers down connected equipment if conditions become unsafe, then resets automatically when normal conditions resume. This minimizes long-term wear and lowers risk of surge-induced damage. The 10-amp rating and compact form factor suit mounted setups behind TVs or in AV racks where space is at a premium. Potential downsides include plastic housing and a higher price point relative to basic models, which may be overkill for non-audio-visual users.
