Speaker Amps
Speaker Amplifiers: real current for real loads. This archive focuses on integrated amps and power amplifiers built to control passive speakers—whether you’re running a nearfield desk setup or a compact room system. Most listings are pre-owned / open-box, documented with clear unit-specific notes on terminals, controls, idle noise behavior, heat, and cosmetic wear where it actually shows.

Desktop vs room: what do you actually need?
The right amp depends less on headline wattage and more on listening distance, speaker sensitivity, and how tough the load gets in real music.
- Nearfield (desk): short distance listening reveals noise floor quickly. Prioritize low-noise idle behavior and a usable volume range.
- Room listening: longer distance and bigger dynamics favor cleaner headroom and stable load control.
- Harder loads: 4Ω dips or low sensitivity speakers benefit from stronger current delivery and power supply stability—not just “big numbers.”
Tell us your speaker model, room size, and listening distance—we’ll sanity-check compatibility before you commit.
Loop Certified checks (speaker-amp focused)
Used amplifiers have specific risks. We focus on practical safety and “daily ownership” checks before shipping.
- Output Safety Verification: we check for abnormal output behavior (like DC offset) that would indicate a potential risk to speakers.
- Hum & idle behavior: checked for abnormal mechanical hum and obvious noise in normal operation.
- Low-volume balance: volume control behavior spot-checked for severe imbalance or obvious scratchiness.
- Terminals & grip: binding posts inspected for damage/looseness and usable cable/plug retention.
- Switching: input selector and buttons checked for consistent actuation.
Need a specific verification (inputs, remote, protection behavior, voltage, or speaker connector type)? Message us and we’ll confirm before checkout.
Refine by architecture (quick guide)
- Integrated amplifiers: simplest system wiring (preamp + power in one chassis).
- Power amplifiers: maximum flexibility when you already have a preamp/DAC with volume control.
- Modern Class D: compact, efficient, often desk-friendly—pairing and gain behavior still matter.
- Class A / Class AB: traditional “heavy iron” approaches, typically larger and warmer-running.
If you tell us your speakers and goals (quiet nearfield vs room impact), we’ll point you to the right architecture first.
Shipping, voltage & heat
- Heavy shipping: amps are packed with reinforced protection for corners and transformer-heavy chassis.
- Voltage: 110V vs 220V matters—verify before checkout (we can confirm for you).
- Heat management: some amps run warm; ensure basic ventilation space.
- DOA window: 14 days (arrival functionality issues).
